Put in a new thermostat, new water pump, and bled the coolant lines. The radiator fan only turns on when the a/c is on, otherwise, when the a/c is off the engines normal cooling fan never turns on, even when it is quite obvious that it should be turning on as it begins to overheat.

Swapped the cooling fan relay for the power window relay and this has not helped. (Power windows work fine still)

If it were to be a bad head gasket, wouldn't I see a leak of some sort, or perhaps coolant in my oil? If so, I do not see any of these symptoms.

Any suggestions?

is your reservour tank full? your oil look chocolate milky? white smoke coming from your exhaust pipe? get the snap on test for blown head gasket.

i think it is a blown head gasket, but i could be wrong.

No smoke from the exhaust pipe, res. is full (to spec according to the markings on it), oil looks norm. Where can I get this test?

 

I had an overheating problem with my 95 accord too. I changed the water pump, thermostat, timing belt, and finally the radiator (it was so corroded that during a radiator flush it cracked!!!). It had a slight leak, and it turned out that one of the clamps on the lower radiator hose was old and loose. Changed that along with that lower radiator hose, and hasnt overheated since.

If your headgasket was bad it would run like absolute ****.

Replace your radiator.

 

your fan should be switching on without your a/c check t he plugs or fuses

 

Thermoswitch A should cycle the radiator fan ON when coolant temp reaches 199F (93C). It's located on the thermostat housing behind the distributor. Remove connector from thermoswitch and short the connectors. Radiator Fan (pax side fan) should come on and run constantly while short is in place. A new thermoswitch should cure your problem.

good luck

Will try this tomorrow!!

 

fyi - that part was faulty for me when i had this problem, it's a 2 minute fix and costs about $35 from a honda dealer.

 

I shorted the Thermostat A located on the thermostat housing and it makes the radiator fan kick on like it should. I reconnected it to the sensor and of course the fan didn't turn on even though the temperature gauge read above half way. When turning off the car, and only when the car is not getting any power (meaning not turing the key to click 1 or 2) will the fan turn on.

Still the Temp. A gauge?
Will swap tomorrow to see.

 

that's exactly what mine did...what this means is....

since the jump/short worked -- the problem isn't in the wiring -- it's on the actual switch -- the part that screws into the t-stat housing that you connect the green connector to. you need to swap that part out -- go to a honda dealer - they'll set you up.
