Question about 1995 Honda Accord

1 Answer

I have a 95 accord LX. I've had some overheating problems and neither engine fan comes on. I tested the A/C fan by unplugging it and testing the power to the harness. It had power to the connection. Would like some advice and or wiring diagram to test the cooling system fan before buying 2 new fans. Thanks, Earl on Maui

The AC cooling fan (in some cars) is tied to the operation of the AC only. Others are used as auxiliaries even when the AC isn't in use. Your normal fan is likely controlled by a thermal switch located in the bottom tank of the radiator and these are not uncommon failures, not terribly expensive or difficult to replace. It may be sloppy, but it is safe to leave the battery connected but the key removed when doing this; there won't be power to the connector if the engine is cool.
Check the lower radiator tank for a largish hex-headed sensor with one or two wires coming from it. It (or they) will be plugged into a mating connector. With a container to trap lost coolant (it can poison animals) and a tight cooling system, these switches can be removed and quickly replaced with little coolant escaping. Use Teflon tape on the threads of the new switch and do not over-tighten the switch when installing.

95 firebird the cooling fan wont come on unless I unplug the fan sensor then it comes and cools the car right down

The fan relay is grounded by the computer (ECM) so you need to test that pin on the ECM connector. When you unplug the ECT sensor you send it into default that is why it runs. Please keep in mind that the fan is not activated until the engine reaches 220F-225F that is well passed the middle of the temperature gage scale . Make sure you really have a problem.

1997 accord lx. Overheating at idle but not when moving. I hear cooling fan come on after I turn off ignition, What can it be?Should fan come on when I turn on AC?

fan not running full speed

dirt and junk packed in the radiator. up front, both if A/C

sure the fan must come on overheated. at all times.

the FSM covers the tests for that, ever seen any FSM>????

read the book or look on

if the fan works, and the rad fins are not packed full of junk, then the RAD tubes in side are clogged, (ask for simple $20 tool that tests this)

all cars overheat , if the fan fails.

no moving means there is no air, no air and the RAD is just a useless brick. the air must flow.

it is really just a heat exhanger, coolant > air.

is the AF at 50% , usning the $2 Prestone test tool?

AF= antifreeze coolant.

97 accord lx overheats unless ac is on

If the cooling fans are not coming on when the vehicle is overheating try this.

Look for the coolant temp switch B. it will be located near the thermostat housing on the back side of the passenger side of the engine (follow the lower hose to the engine). It will have a white with green wire and a black wire. Unplug it, turn the key to the run position, the engine does not need to be running. ground the white with green wire. if the fans come on replace the coolant temp switch B sensor.

the timeing, Mazda will run hot if the timeing is rong.

I have a 92 accord LX. I have replaced the Radiator and the hoses, thermostat and fan switch. Car is still reading hot in a matter of 5 to 10 mins of running. Fluids are topped off. I am not sure why it is...

If you have no air in the system, cooling fans & water pump are working properly, and you didn't install the thermostat backwards, you could have a head gasket problem. Also, make sure the gauge is reading correctly, and the engine is actually hot & the gauge is not giving you a false reading.
If you installed the thermostat upside down, it will not open to allow coolant to circulate. This 5-10 minute time frame you give points to a water pump or thermostat.
I hope this helps.

2003 Honda Civic LX 90k miles replaced parts: thermostat, radiator cap, radiator. major timing belt job including water pump. Car is overheating: When i am idle coming off the highway the gauge...

it is possible that when the water pressure rises in your radiator, and the radiator shoots the water into the reserve tank, that hose is not properly put on(happens alot when changing radiator) and the coolant leaks rapidly through there. another thing i suggest is observe your fan behavior. fans usually are only supposed to turn on for a couple of seconds, around 10 or 15. park your car, and let the car reach normal operating temperature. when the car starts to over heat, check to see if your fans turn off at all. if they do, then it is most likely the tw swith,or the water temperature switch. if you notice the fans stay running, then i suggest obesrving your hoses and replaing any that spill coolant because even a pressure test on your cooling system can miss a small pucture in a hose, which after a while will cause your coolant to leak, and your car to overheat. hope this helps. if still nothing, drop a comment and ill help you out somemore, but for now, this is the practical thing to do. hope this helps, goodluck.

Replaced fan twice and it still wont run

check the temp sensor on the lower radiator hose. Have it tested by pulling the plug on the sensor. It is located at the end of the hose towards the engine. If you pull out the plug the fan should go on. If the fan turns on you may need to replace the temp sensor. If it does not turn on check the relay usually found in the small plastic boxes under the hood. The cover of the boxes usually has a diagram to tell what the components are.
