Suzuki swift 2005 1,3 petrol overheated .coolant fluid was boiling but didn't seem to leak .started the car again drove a couple of miles and the same again.


check to see if the cooling fans at the rad are working. if so then change the thermostat and refill the system. if not then have the head gasket checked for cracking. make sure the coolant is circulating if its not it could be a plugged cooling system or even a water pump impeller problem.

Monte carlo blows cold air and overheats


It really runs hot within a minute of starting ?
An engine that runs hot in a few minutes is often having problems with the water pump or a blockage in the cooling system. The thermostat does not open until 195 degrees which takes 5 or 10 miles of driving.
During that time, the water pump should be circulating coolant in the block and the heater hoses.
A leaking head gasket should be putting extra pressure into the cooling system, and-or dumping coolant into the cylinders which would come out the exhaust pipe. But it should still take a few minutes for the engine to reach the boiling point of 240 degrees.

2001 monte carlo ls 3.4 overheats!! replaced everything


You have to bleed the air out of the system. There are 1 maybe 2 bleeders on the front of the engine on the cooling system bypass pipe one near the upper hose the the othe on the drivers side of the pipe. They are brass with a small bleeder valve in the middle. Get the car up to temperature and take your time to allow all the air out. Refill cooling system after it cools. Hope you didn't do any damage running it hot.

In my 2005 chevy equinex within 5 minutes of turning the car on the overheat light comes on and the gauge will start bouncing around.


It's possible that an air bubble may be trapped in the cooling system. Did you allow the coolant to run low at any time? If the radiator has a cap, try ramping the front wheels and running the engine with the radiator cap off. This should allow the trapped bubbles to escape. Add coolant as needed.

Dashboard overheat warning light blinks continuously after 5-mi


It is not the thermostat since it only overheat on stop n go situation. Most likely cause is a bad radiator fan. Turn on the AC and see if both the radiator, and the condenser fan works. They should both be working when the AC is turned on. Lets stick to this for now. Let me know what happened. I don't want to confuse you with too many possiblity.
