Question about 1993 Oldsmobile Cutlass Supreme

1 Answer

My 93 olds cutls suprm is overheating. Over a course of events I have replaced a radiator hose, thermostat and replaced the radiator. The service engine light comes on. My drive belt is ripped to shreds and I get that replaced. Two days later I get the air conditioner fixed in my car and when I leave the shop it over heats and now the car won't start. Are the heads cracked? If so how can I tell.

Pull the spark plugs, they should all be the samo color, if any are light tan you have coolant in the cyl, you can also pressurize the rad and check for leakage into the cyls, you will require a probe, or the rad professionally checked for exhaust in the system, other symptoms are rough starting and smoke out of the exhaust

I have a 1988 chevy s10 4 cylinder. Its over heating off and on for the last week or 2. I just replaced the thermostat and flushed my radiator but its still overheating


Drive the vehicle until operating temp. Turn vehicle off and CAREFULLY put hand between engine and radiator. If you feel any cool spots on your hand on the radiator side, you have blockage and are only using a fraction of the radiator to cool with. This is most likely the issue. But here is a list of what I would do first. Drain fluid. Remove thermostat. Install thermostat housing without thermostat. Run a flush through engine following instructions for deep cleaning. Drain . remove hoses. Run water through block. Make sure water can pass through. Replace thermostat. Run hose through radiator. Replace all hoses fill it back up and check again. Also replace hoses if they are old or weak. If the problem occurs going up hills but seems OK on flat ground I would blame the radiator.

Did you check if the fan starts up when the car has warmed up? The switch may have stopped working. Otherwise clean out the radiator and the outside. Make sure the thermostat is opening, even though it is new doesn't mean that it works. Start from cold and hold the top hose, it will get hot suddenly if it opens. Make sure all the hoses are clear and not collapsed inside.

My 2000 dodge caravan is overheating and my overflow tank is literally overflowing. I have no leaks in radiator or hoses. Could it be my waterpump or thermostat or just a clogged hose.


Yes, it could be a few issues, I always believe to go the cheapest route first, so you are not just replacing parts to be replacing, Based on your description, Normally it would not be overflowing if your pump is not working, It could be a clogged hose, you would have to flush system to see if that was the case, but based on my feeling, i believe it is a stuck thermostat, If your tank is overflowing, it would have to be a main hose block, but i don't believe that is the case, i would have thermostat replaced, to confirm that, for a around 50 bucks (if you stay away from dealer) you can have the radiator flushed, which is a good idea anyway, then you will know for sure it is the thermostat, and they can put that in after they flush it, or you can put thermostat in, pick there brain, when they flush it, and they can point where it is, it is just a couple of bolts to take off, clean gasket area, replace with new gasket, after of course taking old thermostat out and replacing with new one.

I hope this helps you, (again, i think it is thermostat that is stuck) thanks Mike from fixya

The car keep overheating, there is water in the radiator and the resevior tank 2000 jeep grand cherokee i check the oil their is no water found in the oil the water from both unit stays full


Sounds like your thermostat is stuck closed. Shouldn't be more than a $20 part from autozone and is simple to replace. Follow your top radiator hose to the motor and it will connect to your thermostat housing. Disconnect the hose (antifreeze will run out) unbolt the housing, and replace the old thermostat. Refill radiator and bleed the system.

1990 SUBARU OVERHEATS WHILE DRIVING


1990 Subaru overheating condition.

The entire cooling system needs to be checked.

1. If the coolant level is fine - and low coolant level in your cooling system is not the problem - you need to investigate further.(see 2 below)

If the coolant level is low it needs to be topped up with the correct spec coolant and then the cooling system checked for leaks which could be faulty/worn hoses and/or a leaking radiator. If the car continues to overheat after running with the correct coolant level refer to 2 below.

2. If your coolant level is fine the entire cooling system needs to be flushed out and replaced with new coolant of the correct spec. ( If this has not been done for a couple of years it should be routinely carried out in any event every 2 years regardless of any problems).

Whilst this is being carried out the thermostat needs to be removed and checked. If it has not been recently replaced, a new one of the correct spec should be fitted. It is possible that the overheating is being caused by a sticking thermostat which is impeding coolant flow between the engine and the radiator once the engine warms up.

At the same time the water pump should be removed and inspected. If the pump has never been replaced or has not been replaced for many years it is on it's last legs. A faulty/corroded water pump will be unable to flow sufficient coolant through the engines cooling system from/to the radiator and the engine will overheat.

Any old or tired looking rubber hoses (radiator and heater hoses) should be replaced while this work is being carried out.

When the servicing is completed and the new coolant added, the system will need to be bled of air. If this is not done air in the system will impede coolant flow and the engine will overheat. The entire system should then be checked for leaks.

Do not operate your vehicle whilst you have this overheating problem except to get it to the nearest reputable auto service center. You can do very expensive damage to the engine if running it overheated .

Its overheating should I start with the thermostat if so where is it located 93 pathfinder


Yes, start with the thermostat.
Follow the top radiator hose, it will be connected to the thermostat housing. The thermostat is behind that. Drain the coolant out of the radiator before removing it.

Buick is overheating


Follow the radiator hoses from the radiator to the block. Check the upper radiator hose first. At the end of one of these hoses will be a housing to which the hose is connected. The housing is bolted to the block. The thermostat is in that housing.


Remove termostat housing bolts. Note orientation of old thermostat. Clean gasket material off housing and block. Put on new gasket, install thermostat. Replace housing, etc.

You may have to disconnect/remove other parts to get to the housing botls, maybe not.
