Check for bubbles in the radiator engine warm with the cap off,if you see a continuios build up of air or violant purging you probably have a blown head gasket or cracked head. Talk to me.
Blown head gasket?
My 2001 Nissan frontier 3.3 v6 engine is overheating. I changed the thermostat but it still overheats.
Sell It!!!!!
more than likely you need a new radiator for it, when you install it back flush the engine.
water pump. thermostat.
check the heater core stopped up radiator
A thermostat that is stuck in the closed position is a very common cause of overheating. A new thermostat should be installed every time the coolant is changed.
Either the water pump impeller is loose on it's shaft, or you have a leaking head gasket.
If the radiator or reservoir cap is bad it could cause overheating because the system will not build up the proper pressure. Also the fan clutch could be worn out which would keep the fan from spinning fast enough to cool the radiator.
Remove the Radiator and have it serviced if they are able to. If not you will need to replace it, would be a good time to replace the Radiator hose's as well. Hope This Helps.
If your 1995 Oldsmobile Aurora keeps overheating and the issue is not the thermostat or the water pump, it could be the cooling fan. It might also be the radiator (leaking) or the hoses between the engine and radiator, or the shroud could be clogged or damaged.
Flush out the radiator, it could be pluged to the point its not cooling and will blow another hose or worse , head gasket. A good flush would be my choice. Good luck rick
