    When fan cycles, tempurature is at normal. No leaks. 50/50 coolant mixture. Heater works. What do you mean, does the heat work with fan?

Be sure the radiator is full of coolant, Start the engine when cold, while engine is running feel the top radiator hose. As the engine warms up the upper radiator hose will suddenly get hot when the thermostat opens. If the upper hose stays cool, the thermostat may be stuck closed. If thermostat is stuck closed It must be replaced.

Without knowing more about your car, this is all I can recommend.

Overheating in 91 honda accord

Remove the thermostat and run the engine at idle until it starts to overheat. If it does then the radiator may have clogged veins and needs replacing.

Can a broken radiator cap cause a 2005 honda to overheat

well... your radiator cap should fit properly so start there. If that doesn't work the next step would be to change the radiator valve which should have been done when you changed the radiator... but if they gave you a cap that doesn't fit, why should they do anything else right. You can also change the tempeture valve going into the engine... it may be recording wrong. good luck

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.

1994 Honda Civic LX\overheating within 2 mile drive

Remove and raise upper hose at thermostat end and remove lower rad hose.
Fill rad with a hose and watch for flow from bottom rad hose and/ or bottom rad hose connecton.......water should fall though rad easily.
Honda rads are cheap.....any restriction....replace rad.

Remove thermostat....fill thermostat housing with hose and watch for water flow at bottom rad hose.
Flush good.

Remove heater hoses.......flush back and forth until a good flow is present "With heater control set to hot" if no or poor flow....replace heater core.

Stop leak can plug everything.

Also.......not likely causing over heating....but your mileage,if you do not know if the timing belt has been changed.....CHANGE IT NOW!
Water pump is optional at this mileage.
