What does it sound like? Does it run ok before it warms up? Did you run out of oil or coolant before it started making that noise? How does it run under 35mph? Is it automatic or stick? If automatic, does it shift properly?

Thanks for replying. It sounds like grinding /growling, like something is blocking the gas to flow beyond 45mph. It's wicked loud. I think it did run out of oil when I got home. The car is still running ok under 35mph. I checked the coolant tank. It sort of full but the white tank has about 1/4 on it and it doesn't change. It's automatic and it does shift properly. I'm draining the coolant tank tomorrow and changing all the spark plugs. I have only used the car for about 50/100 miles since we changed the oil and today it's empty. This car has about 139,000 miles and it was running fine until I travelled for about 400 miles. How can you tell if the timing belt is still ok?

I don't think there is a good way to tell if the timing belt is ok. If it is in one piece with no frayed edges it is doing the job for the moment. It should be replaced every 60000 miles, regardless how it looks. More important is the timing itself. Have someone check the timing with proper equipment. But check the following items first.
 
How low does the oil get? In 100 miles, does it burn 1 quart or more? If so, you should also see black smoke coming out of the tailpipe. If this is the case it is likely that something happened to the piston rings. Have a mechanic check the compresstion in each cylinder. I don't know how much a ring job should cost. But whatever it is, it will not be worthwhile unless you are absolutely sure that low oil level did not cause other internal damages.
 
OR the car is leaking oil in the driveway...Easy to check.
 
OR the oil is leaking into the cooling system. Take the radiator cap off (when cold) and see if the coolant comes up all the way to the cap. When you drain the coolant make sure it is nice and green with no oil mixed in it. If you find oil in coolant...head gasket is blown and you probably don't want to spend the money to repair that.
 
Don't change anything expensive...just yet. Spark plugs did not cause this problem, but they might be dirty if the engine is burning oil.
 
I am sorry to have to suggest this but I suspect that the oil level was allowed to go too low, and bearings and piston rings got burnt up, hence the awful noise. You may have timing belt issues as well, but that cannot cause the engine to burn oil. Noticeable change in oil level in 100 miles is not good. Are you sure?

The radiator cap has Brownish color. If the head gasket is blown. I really don't want to spend to much money on this car.
Thanks so much...

How much to fix? by fred3

I've got a 1995 Geo Prizm LSi, with only 40,000 miles on it. Runs great, and have had minimal issues. Recently, my wife had a minor parking-lot fender bender, where the car was hit in the front, on the right hand side. There's some damage to the front bumper, the front headlight was pushed a little out of place, and the hood is a bit out of shape. We were quoted $2,000 to fix, about half of which is for the hood.
 
I would assume that the bumper and headlight must be fixed, as potential safety issues on the car, but what abut the hood? Is there a safety issue with the hood, or is it purely aesthetic?

I'd say it's cosmetic if these conditions are met:
 
1. The hood does not block driver's view.
2. The hood is not damaged in such a way that it catches a lot of wind at high speed. If it does, the hood release latch is the only thing that's keeping it from flying off the car. The latch itself may have been damaged by the impact, so you should inspect it very carefully.
 
A used hood from a junkyard should be available at a fraction of the quoted cost ($1000). You might want to look into that option.

1999 Chevrolet Prism Cigarette Lighter issues by oolieiv

I was using an inverter in the cigarette lighter of my 99 prism . Suddenly, it stopped powering the inverter. Then when I tried a cell phone charger in it, that didn't get any power either. I checked the fuse and it looks to be fine. I was just wondering what else I might be able to do in order to fix the problem.
