89 Buick Century. My moms car starts fine, drives fine, but after a few minutes it heats up...........?

Question

turns off and does not want to start. I have changed to fuel pump, spark plugs and cables, and it still does the same thing.. Can some one help?

Answer 1

Heating up? Change the thermostat. It is probably sticking closed. A new one will probably solve the problem. Does she have plenty of anti-freeze in the radiator? Is the radiator stopped up? Does it have a belt driven cooling fan with a clutch? If so, check the fan clutch. With the engine stopped, you should feel quite a bit of resistance when you turn it by hand.

Good luck. Pops

Answer 2

So you mean it starts fine when cold, but not after it heats up? What engine do you have?
There is usually a schrader valve(like bicycle air valve) where you can check for fuel pressure on the injector rail. Don't change parts unless you know they're bad. If it starts and runs, then the pump and plugs and cables are probably not the problem. Heat related issues can be caused by ignition modules, coils or catalytic converters being plugged up. There are ways to check each of those conditions. If you are mechanically inclined you should have no problem with it, otherwise your best bet is to find a competent mechanic to perform the tests.

Answer 3

None of the things you changed would have anything to do with overheating. Solve that problem and you should be okay. If you find the thermostat is good, and the fan is running, with the car cool reach down and grab the bottom radiator hose. If you can squeeze it closed, that will be the problem. It has a spring in it that holds it open (it wants to collapse) and sometimes that spring will rust away.

Answer 4

Overheating is caused by the cooling system, and not the parts that you changed. You'll have to check your radiator and hoses for any clogs and rust build-ups. If there is any build-up, have it flushed. Also check your water pump to make sure it's running fine. Lastly, check the radiator fan switch and thermostat. You can remove the thermostat all together if you like.

Answer 5

If it heats up after a few minutes, that would imply that either there's obstruction in the cooling system, or the water pump is not running. Once the engine has cool down enough you can restart it, but then it'll just overheat again.

IMHO, of course.

Answer 6

what variety of automobile is it? If it relatively is overheating by using a foul thermostat then taking it out will restoration the subject. yet you will desire to no longer have the potential to take it out, you have gotten to interrupt it aside and placed the hoop and seal back in. would desire to or no longer it relatively is too plenty Air in the gadget would desire to or no longer it relatively is that the producer became an fool and designed a delicate part of the timing belt to coach the water pump and now it relatively is no longer turning it at finished speed because of the fact it relatively is slipping. if so then you definately choose a sparkling timing belt, or tighten up the only that's in there. in case you do take the thermostat out or destroy it aside, try the vehicle first earlier happening a protracted holiday, ascertain that became the subject. you may continuously warmth up a pan of water and placed the thermostat in it and spot if it opens, if it does not then you definately would comprehend that's a foul thermostat

Answer 7

Check the cellonoid (I believe that is how it is spelled) or O2 sensor, they could be a part of the trouble. Did you check the cooling system water pump? What about the catalytic converter? Thermostat?

Answer 8

sounds like yu blew the head gasket when the water cant go threw the motor. haveit pressure tested for leakes& check the thermostate also good luck dude
