Check coolant level, make sure car have half antifreeze and half water,if coolant level okay, car overheating when starting up driving is faulty thermostat and radiator cap.if car over heat while sitting in long line of traffic.your coolant temperature sensor could be faulty, or coolant fan fuse blowed or relay failed.hot wire cooling fan if it works, problem is the wiring or pcm, if every thing working okay.check engine oil if look like milk shake or you have a lot white heavy smoke coming out the exhaust, you have a blowed head gasket.

My 1999 alero is overheating and engine coolant is leaking


hi, i dont know about the dipstick, but your overheating problem is most likely to be the thermostat...sounds like its stuck in the closed position,not allowing colder water to circulate, hence the overheating.......needs changing

Black clamps for rear seat? Where do they go?


There are 2 small kinda u shaped clamps that sit on the floor. Those are used to hold the seat down to the floor of the car. You set the seat down and push it in toward the back of the car as well as down at the same time to lock it into those clamps. If you look up near the edge of the area where the seat goes you should see the holes for those brackets.
