Question about Cars & Trucks

1 Answer

Have a oldsmobile alero that over heats every 5 to 10 mins, always have to pull over. Thinking there might be a pin hole in hoses that enlarge under pressure, do not see any coolant leak at all. Think

Never can find coolant leak, not present when vehicle is idileing. Temperature guage in car increase while driving. Vehicle must be pulled over every 5 to 10 min, while in use. Check resivour and there is no coolant left. Keep having to refill with water each time vehicle is pulled over every 5 to 10 min's. Thinking it is a pin hole in the hoses when they are under pressure causes a pin hole to expand and cause the leak. Radiator cap looks ok! Started to think thermostat, do i need to check the housing, is there a t-stat there?

That means evaporitive emissions control system leak that is small. Most of the time this points to a bad gas cap or loose gas cap but not always. IT could be from a valve or bad hose.

On my 1999 oldsmobile alero. the overflow hose seem like it got a pin hold in it. because when i was driveing all this stam was comeing out. where is it comeing from?

Yes it could be a leak in the hose between the radiator and the overflow tank. The tank is supposed to hold excess coolant when the engine is hot and then release it back into the radiator when the engine is cool.

Where is the thermostat on a 2000 alero 2.4 liter

The thermostat is virtually always right at the engine end of the upper radiator hose. There is virtually always a housing that the hose clamps onto, which housing is then bolted onto the engine. The thermostat is under that housing.

Can you tell me were the thermostat is located on a 2000 alero can you send me a diarpham of location

Almost always , thermostats are located under the filler neck on top of the engine. The filler neck has the upper radiator hose attched to it, so follow the upper radiator hose from the radiator.

Car is over heating. Alero 2001

If you changed the hoses and thermostat and the car is still overheating, then the next thing to look at is the water pump. See if the water pump is leaking water from a vent hole. If it is, then the water pump is defective and will need to be replaced. Sure hope this helped.

2001 Oldsmobile Alero will not start. The car turns over but just will not start. Plugs are 4 mths old, tank is full of gas battery and alternator are working. Anybody out there know of anything we could...

you can also try pulling the fuel pump relay under the hood and put it back in. works on my 2000 alero. and yes if the security light is on, you need to turn the key on and wait about 10 min. until it stops flashing, then turn off, then start car.
