a manual at the parts store. But they still don't show everything. If you know some one that works at a garage, and can get you copies from aldata or mitch. These are the best you can get.

You should be able to tap into either brake light as long as your turn signals are separate from your brake lights. If they are the one and same bulb, you will have to add a diode to keep that 3rd light on the camper from flashing with the turn signal. The diode is a 1 way item, meaning it can be installed backward and the 3rd light won't work. You could go to a local stereo shop to radio shack to get the diode and they can show you which way to install as well as ensure you have the correct parts to install.

Bad news you have a blown head gasket. And possibly a bad head.

Did you just bleed the one brake or all of them. You need to bleed them all. Also, be careful with bleeder screws the are quite easy to break. Check the level of you brake fluid, if the reservoir is still full bleed all four brakes again. One at a time, and use a piece of clean hose with about a 1/3 of a jar of clean brake fluid and the hose running from the end of the bleeder screw into the brake fluid in the jar (to prevent air from being pulled back into the line. 1/8th inside diameter rubber hose about a foot long should do the trick. Make sure you have a helper to push and hold the brake pedal while you loosen the bleeder and tighten it back again then tell your helper to let off the pedal. Repeat until no more air bubbles are coming out of the lines. If you don't have a helper, you can open the bleeders one at a time and let gravity bleed them (not the best way but better than nothing). Make sure you have plenty of good brake fluid. Don't use fluid over a year old either. Those are just simple basics, could be a power booster as well. Here is an excellent tutorial on troubleshooting brake problems. Hope it helps.

If you either go OnLine or Call the Service Department of a local Chevrolet, they can either fax or email one to you. Try the dealer you bought it from, give him a little sadness, tell him you can't drive without the belt otherwise you would have brought in to him for service.
I'm sure that they will be accomodating to you.

Best Regards,

Hi the bolts are located behiind the power steering pump pulley. This pulley is pressed on, and a puller is required to remove it. once the pulley is off, you will be able to remove the bolts. Good luck...coop

If the connector to the coolant temperature sensor is loose, that could be causing the problem since that controls certain functions of the computer when the vehicle is warm vs. cold.
