SOURCE: No heat. Fan blows cold air.

I think u may have an air temperature control blend door problem, the door is moved by a small electric motor, it is stuck in the cold position.

SOURCE: Overheats at idle only, fine at speed or higher rev

Generally the bottle will give you some idea on level but if you have a cap on the radiator, that's the best place to check or fill. (only open cold) Also make sure that if you have an electric fan, that it's coming on when hot. Your computer also aids in cooling by advancing/retarding timing. It may not be.

SOURCE: Car overheats stop and go traffic, heater works over 2 rpms

I had a similar problem with 2003 nissan sentra, no heat , and car would stall on road on and off. Became a problem more frequently stalling. Took to nissan and they said it was head gasket. Fixed it and never had problem again. But i had it fixed at a local dealership since nissan was charging 1000.00 compared to 550.00. I replaced water pump and thermostat first b4 this and no cigar.

Why does my car Overheat?

Possible thermostat faulty, Thermostat automatic, stays shut, till water reaches correct temp, if it goes faulty, (ie) does not open after reaching running temp, water will not circulate, so engine overheats

Verify fan operation(be carefull not to let the car overheat) and if they dont work try these steps. (If you have electeical know how)
check all fuses
check relays by swapping with another known good relay.
look around with a tester and see where along the circuit you are getting voltage.

97 Honda Prelude, when using the A/C the car overheats when in stop and go traffic or stopped. If I go 50 mph or more the car is fine with the A/C on. What part do you think needs to be replaced

is the cooling fan working with and without the a/c on.this could be the problem and is it spinning fast enough.if its starting to seize up it won`t be turning at a fast speed like it should.with the a/c on it puts a load on the motor that causes it to work harder thus run hotter.another thing to check is the rad flow as if its not flowing enough coolant it can cause this as well.have you changed the thermostat as if its not working properly it could be not opening as it should again causing the motor to run hotter.

My car over heafs when stuck in traffic. It's a Honda Prelude 89 model.

make sure you cooling fan is coming on (this should when the temp guage starts to climb) and also make sure the temp sensor that turns it on/off is good. You could also have low coolant or bad thermostat (the wrong mix of coolant) or oher major mechanical issues but start with the fan and coolant level/mix

I have a 1998 honda prelude h22 vetc automatic with 178K the motor runs fine but the transmisson when i put it in reverse i knocks the it will do fine threw first kinda slip in second and then not go into...

Definitely change the transmission oil - could be some rubbish in there stopping the actuators working correctly. If that doesn't work, could be time for rebuild with new friction material in the clutches.

A/c not working think fan isn't coming on.

Yes with airflow it work (on the interstate) but with no airflow to get rid of the A/C heat causes engine to overheat. Let's look at two possible things...first the A/C condenser fan by the radiator & then the A/C water temp switch.

Check the 30amp CDS FAN fuse (replace if blown) if it is OK then replace the the Fan#3 RELAY (which turns on the A/C condenser fan)...Then if needed replace Fan#2 RELAY (which can also control the A/C fan speed).

The Fan#2 relay can wear out and cause the type of problem your having

Overheating- smaller fan is fried would this cause it to overheat

Is it an hour idling? If you are overheating going down the road, this is either a thermostat, or a plugged radiator. The fan will contribute to overheating sitting still.

Car Running Hot

Hi, are you sure u need a new thermostat? Running in the mid temp range is ok. If u think u need to change it, here's the info. I believe your Prelude uses a 195 degree thermostat, but go to a good parts store and give them the year make, and model and ask them what thermo. u need. Also get a gasket. The thermostat is located at the end of the radiator hose (the top hose). Disconnect the house at the 'housing' and remove the housing (2 bolts), the thermostat is now exposed. Pop it out (u might need to persuade it w/ a screwdriver (gently pry it out) and remove the gasket, clean gasket surface. Install gasket and thermostat, being careful that they stay in position when u bolt the housing back in place. Re-attach radiator hose, top off coolant, (50/50 Mix), and last, there is a bleeder valve which I believe is on the housing that u loosen after starting the car, when air stops coming out, tighten and u r good to go. Do u have any idea when the coolant was last changed? U might want to consider it if it's been a long time, or u r not sure. Let me know how u make out, or if u have any questions. Good luck! countrycurt0
