If your cooling system is building up pressure it may be an indication of a leaking head gasket.A leaking head gasket will act up by building up pressure in the cooling system, overheating, and eventually, will crack the head and or block. Have a cooling system pressure tested on this car.Not what you wanted to hear, but I hope this helps you. Mark
Waterpump, thermostat, radiator, radiator hoses.
the thermostat will be under the THERMOSTAT HOUSING, which is where the TOP radiator hose fits on ie(radiator to thermostat housing) this keeps the engine at an OPTIMUM temperature BUT can be A cause of OVERHEATING IF malfunctioning
A Nissan Frontier may be overheating because the radiator is cracked. A thermostat failure can also cause it to overheat.
Is your fan coming on?
Check the fan clutch, it may not be working properly.
Probably the thermostat stuck shut.
low radiator fluid or a possible bad thermostat.
Cooling fan not working? Thermostat not opening? Plugged radiator? Water pump not working? Defective radiator cap? you have to bleed the thermostat
Blown head gastet, radiator leaking, thermostat needs to be replaced Blown head gastet, radiator leaking, thermostat needs to be replaced
If the engine is not overheating and the temp gauge reads normal, the thermostat is doing its job. If the engine is overheating, the thermostat may be stuck and in need of replacement.
There are a few reasons a vehicle is overheating. The common causes are the thermostat, water pump, radiator, or the fan stopped working.
It could be your thermostat how is the fluid in your radiator?
The top radiator hose is above the thermostat. If the top radiator hose is hot, the thermostat is opening. The thermostat is not the problem. Perhaps the radiator is clogged up or the water pump is bad. Look elsewhere.
If your truck is overheating!!! Then check the upper radiator and lower radiator hose's , if the lower is cooler the the upper the either the thermostat is not opening or the radiator is clogged
Could be from a variety of things. Commonly overheating occurs when the car is low on coolant, broke thermostat or the radiator needs repairs.
Low on coolant, radiator fan inoperative, thermostat failed, water pump failed, radiator plugged
Low coolant, failed water pump, restricted radiator, inoperative radiator fan, thermostat,
bad radiator cap leaky radiator leaky hose(s) bad water pump blown head gasket clogged cats stuck thermostat
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.
check thermostat, first, then look for radiator leaks, hoses that might be leaking.
Thermostat, water pump, radiator cap, headgasket, low coolant.
water pump. thermostat.
a 2002 Alero could have several problems causing the overheating. Thermostat, water pump, or clogged radiator issues are the most common causes of overheating.
The radiator may be plugged. Take it to a radiator shop.
Either the radiator is blocked, or the thermostat is stuck closed, or the water pump has failed.or it just needs water.
