Replacing the parts is usually not the hard part unless they are in difficult areas to access or you are not mechanically inclined. Having the right equipment to vacuum the system down and to recharge it to factory specifications and knowing how to use the equipment and knowing what pressures...

It's a good possibility that your compressor is bad. Your low side is pretty high and your high side is low for your outside ambient temperatures.

I've rarely done the gravity bleed method and in a couple of instances where I had to replace some brake lines, gravity bleed did not work at all. In those instances, the vacuum bleed method also did not work, and I had to have a partner pump the brake pedal to get it to bleed. I've have...

Nothing is going to stop the repair because those components are wear items. Earlier oil changes prolong their life. It sounds like you want to do extended oil changes so that is what you should do. Maybe you get lucky and your engine lasts a long time without a timing job repair.

We need a lot more information. What are the ambient outside temperatures? What are your vent temperatures? What are your low and high readings on a real gauge set? The only real way to know what your problem is is to charge the system with the factory weight and put some dye in the system...

Because this job is very labor intensive no one just puts in timing chains and calls it a day. The other timing components are also usually replaced because you don't want to have to pay the labor twice. At the end of the day, it's your vehicle and for you to maintain as you seem fit. Oil is...

There is no way I would go more than 5,000 miles on an oil change with that engine. They are hard on oil and the timing components don't take kindly to extended oil changes.

Installed a new coolant level sensor on the 1999 Cavalier in an attempt to get the low indicator light off on the dash. Installed the new sensor and the light kept coming on. I thought that the new sensor was bad given it's an aftermarket Duralast. I did some research since this sensor slides...

Have you looked at your fuel trims after the truck warms up? Since cyl 1 & 2 are the first two cylinders on each bank, maybe you didn't get the intake plenum gasket on the front seated correctly. The fuel injectors in these trucks also can become problematic as they age. Is the cap and...

Our 92 Chevy Cavaliers have three bolts holding the fan assembly in and one connector to take off and it lifts out the top. Probably a 10-minute job tops. I don't know what they were thinking on this 99.

Replaced the cooling fan on the 1999 Chevy Cavalier today. What a PITA. It will not come out through the top and has to be removed and installed from below but that is a major PITA because of the AC manifold line that is in the way. You have to unbolt the radiator at the top, unbolt the...

I only have one Milwaukee product and it's one of their M12 ratchets. Everything else I own is Dewalt and I've had good luck with them and the one time I did have to warranty a battery; they sent a new one out and didn't even ask for the old one back.

My fiancé's son's 99 Cavalier overheated today, and we had to go to his work to see what was going on. There was coolant underneath the car but not actively dripping when we got there. Overflow tank was empty. I checked out the hoses and underneath the water pump but nothing looked wet in...

Have you tested the wiring down to the compressor to see if you are getting power to it? Have you tried jumping the AC relay to see if your clutch engages?

My MAC master kit looks pretty much just like that Cornwell kit. I agree that there doesn't seem to be one kit that has it all and that is why I bought several different kits.

If your outside temps were 56 degrees, your static pressure should be close to that so you are probably low on refrigerant. Are you saying that the gauges read the same whether the car is running with the AC on and when it's turned off? Whether or not the AC would turn on with those pressures...

Good job. I'm not sure I would want to tackle that job.

Never.

I have two different MAC fuel injection test kits, one a basic kit and one a master kit. I also have Snap On's newest master kit but it's super expensive. I bought all of mine on Ebay in new condition for quite a bit less than list price. The Harbor Freight Icon Master fuel injection kit is...

I don't. Once I'm done vacuuming the system down, I close the valves on the manifold and then the vacuum pump. When I hook the yellow hose to the gauges from the refrigerant tank, I push the Shrader valve down on the gauges for the yellow line until a small shot of refrigerant comes out which...
