Clutch Repair and Replacement

Repairing the On-Again-Off-Again Engagement -
Think of the clutch as a switch between your engine and the transmission. Every time you press on the clutch pedal, you turn the switch off, and no engine power gets to the transmission. Light goes off. When you let the pedal back out, the switch turns back on and away you go. Light goes on. If you let the clutch pedal halfway out, the clutch transmits roughly half the engine power to the transmission and acts more like a dimmer switch.
Repairing or Replacing a Clutch in a Transmission
The clutch is able to perform this on-and-off delivery act by way of four major component parts – the flywheel, the clutch disc, the pressure plate, and the throw-out or release bearing. Since the average clutch is engaged and disengaged thousands of times over its service life all these parts will eventually wear out. Oddly enough that's what they are designed to do.
Caught in BetweenThe clutch disc takes most of the abuse over the service life of a clutch assembly. The clutch disc is one of those parts designed from the start to wear out as it does its job. Like a brake pad, the clutch disc wears out a tiny bit each time it is engaged. The clutch disc lies in wait and endures extreme pressure as it is sandwiched between the two steel surfaces of the flywheel and pressure plates. The material of the clutch disc absorbs friction and allows for the smooth transition of engine power to the transmission from the flywheel through the pressure plate. Dampening springs in the center hub of the disc absorb vibration from engagement to prevent damage to the drivetrain and transmission. Eventually the clutch disc material will wear too thin and the clutch assembly will no longer be able to hold the torque, or twist, created by the engine and will slip. The heat created by this extra slipping will quickly make things worse, and soon the switch will be off for good. Light goes off. Vehicle goes nowhere.
How to Steps
Unit, Not Parts
While the clutch disc is usually the part that wears out first, all components should be inspected or replaced when servicing the clutch. The flywheel should always be resurfaced for chatter and vibration-free engagement. Pressure plates should be replaced if worn. The throw-out or release bearing can also raise a ruckus and start howling as it wears out. Since this bearing handles the load of disengaging the clutch and allowing the assembly to spin freely while disengaged, replacement is usually a safe bet. The pilot bearing should also be inspected as it centers the transmission input shaft in the flywheel and allows it to spin. For these reasons, it is a smart strategy to replace the entire clutch assembly as a unit. Readily available kits, complete with alignment tool, are a great way to get everything required for the job in one box.
Opening the Can
The clutch is one of those parts, like a cylinder head gasket, or a timing belt, that while not prohibitively expensive by itself, can be a real chore to access. On a rear-drive vehicle, getting down to the clutch requires removal of the drive shaft and transmission. On a front-wheel-drive vehicle, the task becomes more complex. And on an all-wheel-drive vehicle, a true maze of components must be removed to get down to the clutch assembly. While replacing the clutch assembly itself usually takes a matter of minutes, getting the transmission and everything else out of the way, and then put back in again can take many hours.
There is no possible way in this short space to outline removal and replacement of all the different configurations of transmissions and drivetrains. Consulting a service manual for procedures, torque specifications, and final adjustment is the only way to go before tackling a clutch job.
How to Steps
Disconnect the negative battery cable. Secure the vehicle on jack stands. Drain the transmission oil. Remove the clutch and shifter linkage. Remove the driveshaft and the transmission.Remove the Clutch and Shifter Linkage
Remove the pressure-plate bolts a little at a time in a circle in order to slowly release the pressure plate from the flywheel.Remove the Pressure-Plate Bolts Slowly and in a Circle
Remove the clutch assembly as a unit. Do not breathe the clutch dust or use compressed air to clean.Remove the Clutch Assembly as a Unit
This clutch disc was slipping. The now glazed, thin surface was worn down to the rivets and about to give up completely.This Clutch Disc Was Slipping with a Surface Worn Down to the Rivets
Remove the flywheel bolts with an impact wrench. Remove the flywheel. Be careful, it's heavy! Always resurface, or replace the flywheel when installing a clutch.Use an Impact Wrench to Remove the Flywheel Bolts
Clean the bell housing and input shaft of dust and grease. Install and lube the clutch fork and throw-out bearing. Test for proper operation. Test for pilot bearing fit on the transmission output shaft.Test for Pilot Bearing Fit on the Transmission Output Shaft
Install the new pilot bearing flush with the transmission side of the flywheel. Drive it in with a drift or a socket that lines up with the outside of the bearing. Install dowel pins if required.Install the New Pilot Bearing Flush with the Transmission Side of the Flywheel
Use a torque wrench to install the new flywheel on the crankshaft. The cheater bar prevents the flywheel from spinning.Use a Torque Wrench to Install a New Flywheel on the Crankshaft
Alignment of the clutch assembly is key. Use the alignment tool to first center the new clutch disc onto the flywheel. Keep the disc centered as the assembly proceeds.Aligning the Clutch Assembly is Crucial
Install the pressure plate evenly. Tighten the bolts a little at a time in a circle, first one, then the furthest from that, and so on. Use the alignment tool to keep the clutch disc centered as you go. Torque the bolts to specification.Tighten and Align the Bolts on the Pressure Plate
Remove the alignment tool. Measure to see if the clutch disc is centered in the assembly. If not, start over!Measure and Make Sure the Clutch Disc is Centered in the Assembly
Reinstall the transmission. The transmission should mate up correctly with little effort. Do not force the transmission into place in an attempt to overcome misalignment. Do not allow the transmission to hang from the input shaft.

Wish you successful and have a nice day
Reinstall the Transmission

Hydrogen fuel cells are an important component to GM's advanced propulsion portfolio

There are many roads on the journey to a sustainable transportation future.
Hybrid vehicles, EVs, biofuels – all of these vehicles factor into the equation. But many consider fuel cell vehicles the road less traveled.
Not the drivers of the Fuel Cell Equinox, however.
The specially equipped 2007 Chevrolet Equinox was part of our 119-vehicle Project Driveway program, launched in 2007. The fleet has accumulated more than 3 million miles, more than any other automaker. By using renewable hydrogen, these vehicles use no gas and their only emissions are water vapor.
The test fleet wasn't just driven by engineers in a controlled laboratory on our proving grounds. Real consumers logged the miles in real-world driving conditions. More than 5,000 drivers have provided feedback on their experience driving the Fuel Cell Equinox.
Like other alternative energy solutions, though, the fueling infrastructure must grow before fuel cell vehicles can go mainstream.
But in the meantime, we're collaborating to refine this technology. Last July, we announced an agreement to co-develop a next-generation fuel cell system and hydrogen storage technologies with Honda. We also expanded our partnership with the U.S. Army Tank Automotive Research, Development & Engineering Center to co-develop hydrogen fuel cell technology.
Hydrogen fuel cells are an important component to our advanced propulsion portfolio. The proof is in the patents: the Clean Energy Patent Growth Index , a third-party monitor of intellectual property involving clean technologies, recently ranked us No. 1 in fuel cell patents filed in the last 11 years. Moreover, according to the latest index we now lead all companies in total U.S. clean energy patents, which includes patents for solar, wind, hybrid/electric vehicles, fuel cells, hydroelectric, tidal/wave, geothermal, biomass/biofuels and clean, renewable energy.
By investing in these technologies, we can ensure that innovation in the lab leads to transformation on the road.

Ford Maker vehicle-to-vehicle communication

Ford V2V
Ford has demoed their experimental vehicle-to-vehicle (V2V) communications technology for the first time in the Asia Pacific region at the Computex 2014 in Taipei. This WiFi-based technology enables cars to transmit data to other similarly equipped cars, including vehicle speed, location and predicted path to warn drivers of potential collision risks and other dangerous situations they may not be able to see yet. We got to check out the feature in a Ford Ford Kuga car at the Computex. Check it out below.

Ford V2V Infographic
As you can see from the infographic, the V2V technology by Ford enables cars to detect fast-moving vehicles before they enter into the blind spot and can also alert drivers about vehicles approaching at a high-speed in advance. This would enable drivers receive alerts of vehicles that are obscured when it is hidden by an oversized vehicle or during sharp turns.
Ford V2V
Ford is looking to enhance the V2V technology with vehicle-to-infrastructure (V2I) communication that may enable vehicles to interact with infrastructure to offer notifications such as traffic jams, accidents etc.

How To 15.6 Gallons into Eco MT Tank

Here's the definitive way to properly increase your tank capacity from 12.x gallons to 15.x gallons.

First, get the fuel pump module from any 1.4L Cruze as long as it's NOT the ECO M6.

Next step is to release pressure in your fuel lines. I just pushed in the schrader valve that's on the fuel rail and had a rag handy to catch the fuel. After that remove the fuel tank. To do this you have to remove all the ECO specific underbody cladding. There's 3 pieces. 2 that run the length of the car and 1 smaller one that runs side to side by the fuel tank. They're easy to remove, just a bunch of 10mm plastic nuts and 2 10mm bolts.

After those are out of the way I lowered the rear section of exhaust by unbolting it right behind the catalytic converter. Just 2 13mm nuts and it'll lower enough for the tank to clear.

Disconnect the fuel filler hose at the tank, vent tube that's right next to it, main fuel line and vent line next to that.

There are 4 electrical connectors to unplug. 1 is on the vapor canister and this one is the hardest one due to lack of space. 1 is on the fuel line, 2 are on top of the fuel pump module. The only way to get to them is to lower the tank. To lower the tank you just unbolt the 2 straps that hold the tank in. 13mm bolts. I bent them down and out of the way. They're easy to bend and bend back without any damage. The only other way to do this without bending them is to remove the rear axle decide.

Replacing Problematic Relays

Coursing through the copper, inside a myriad maze of wires stuffed into the nooks and crannies of the modern automobile is the electricity required to run primary systems such as the starter motor, and secondary gadgets, like heated rear view mirrors. Since different levels of electrical power are required for running some devices over others, the automobile incorporates a relatively old-school electromechanical device to activate more modern innovations.Isolating and Replacing Problematic Relays
Passing on the Power
This device, known as a relay, is essentially an electromagnetic switch that acts the same as one runner passing a torch on to the next in a "relay" race. When activated, the relay passes the signal on to send electricity flowing either this way or that—and the race begins. Insofar as automotive applications go, the relay usually passes the torch onto a bigger, faster, more powerful runner.

The good majority of relays in automobiles are used to channel a small amount of power in one circuit in order to trigger another, requiring a large amount of power, such as the tiny little electronic switch on a cabin climate control computer that activates the big old electromagnetic clutch on an air conditioning compressor. That being said, even fancy computers in modern cars still rely on the old-school electromechanical relay in order to make things work.

Recalcitrant Relays
For various reasons, not the least of which includes turning on and off thousands of times, and spending life in an environment that is alternately baking hot and freezing cold, relays may eventually stop working. When this happens, the switch to activate the heated seat may work fine, but the switch signal will stop at the relay and the big electrical power needed to heat up the coils under your hiney to keep your keister cozy will never be reached.

How to Painlessly Repair Your Vehicle's Broken Pane

So, you've noticed your window isn't there anymore, and Mother Nature is being more intimate with you. Maybe your stereo is missing, or pieces of trash are floating in during your commute. You probably need to check out the cost of window glass replacement. I called one auto glass repair business, but didn't like the amount they would charge to fix the problem. A bit more research via the net and I not only got a market price for a replacement window (one-third what the "professional" wanted), but also found a nearby auto-recycling center with one in stock.
