When the engine is at normal running temp,feel the water hose on the bottom of the radiator.if it is hot then ur thermostat is fine,and its more likely to be a head gasket or airlock problem

    btw your thermostat is located where your top radiator hose meets ur engine

    i believe the stat is actually where your lower radiator hose comes up to meet your engine.. correct me if im wrong but the upper goes back under your intake manifold..

1997 Honda Passport overheating and no heat inside car

Low coolant is the usual culprit, followed by a bad thermostat. When the car is cold take the radiator cap off and check the coolant level and add as needed, then make sure overflow tank is at the correct level. If the radiator is low but the overflow has fluid, replaced the radiator cap.

How would my car run without the radiator fan

bubbling at the RAD cap to the expansion tank is.:
1: overheating, and all cars overheat, parked, running and no fan.
2: blown head gasket. or far worse....
3: bad rad cap, the gasket is bad in side it.

the FSM covers the fan test, read that.
or login to and read engine cooling. section.

Check that the fan is working. You do not give a make or model, so it could be the thermostatic switch, fuse or relay for an electric fan or the viscous clutch if it has that type of fan. If the water bubbles out or you see bubbles either in the radiator or the overflow, you might have a head gasket leaking into the coolant system.

1997 honda accord overheating

well you should first hard wire the non working fan to the battery to see if it is ok, then I would check the engine coolant temperature sensor, it is the sensor that tells the computer to turn the radiator fan on

1997 honda passport heater fan motor doesn't work

check the fuses than check for power and ground at the blower motor plug with the engine running and the switch on high. if you have power and ground replace the blower motor. somtimes the blower motor resistor fails too but than the blower usually only works on high. I replaced 1 of each this week.

Leaks and overheats really fast

hi it sounds like your headgaskets blown you need to take your rad cap off fill with water start the engine see if you see any bubbles in the water or if the water blows straight out its a good indication the headgaskets gone the thing on the right hand side is the expansion tank overflow if this blows water out even when cold the headgaskets gone if you see no bubbles in the water change your thermostat the two fans on the rad have nothing to do with your a/c if that doesn,t work may need pressurising yates210456
