Question about 1993 Honda Civic 4 Door

1 Answer

I have a 1993 Honda Civic EX (2dr) which continues 2 overheat! The radiator has been replaced 3 times. The 1st time it had a hole, 2nd time it was determined that it leaked @ the seams when a pressure test was done & this last time it was leaking from somewhere. The water pump was checked as well as all other hose's. The thermostat(s) were replaced, the system flushed & replaced with new fluids. Also the radiator's fan motor was replaced, the fan works, but doesn't prevent the overheating the other fan (engine fan) is not on when the radiator fan is on. So only one fan seems 2 be working at any given time. The mechanic I took it 2 said that was fine?! But still it is overheating! No matter if you drive on the streets or highway, 4 long or short distances, all of this is DEFFINITELY while the a/c is on, but also occurs while it is off! The temp guage will slowly go 2 the middle then rise up above the sqiggly line in the middle towards the H (hot) then back down to the middle. You can hear the fan turn on the radiator, but not the other fan. What is causing this overheating & how can I fix it??? Any information or help will be greatly appreciated....Thanks! :)

    Have you had a combustion leak test done to check for a leak in the head gasket, block or cracked head? The test involves using a tester that has a blue fluid in it that will turn yellow if there is a combustion leak into the cooling system.

Any motor swap? have a block test done to check for the headgasket... it's possible you have warped the head with the list of cooling issues you have had.

You will need to replace your heaters resister switch, which will make your heater work from 1 through 4 but is not your overheating problem. I would make sure your fan is working when when your engine gets hot.

Do I need to change brake fluid, clutch fluid and power steering fluid in my 2000 Honda ex 2Dr. coupe? It has 97,000 miles on it.


Unless you have a record of these fluids being changed in the past 18 months you should definitely change them. These fluids will degrade over time and need to be changed at appropriate intervals.
You should also flush the engine radiator and cooling system and replace with new coolant to the manufacturer's specs unless this has been done in the past 18 months.
Also ensure you change the engine oil and filter frequently (certainly more frequently than the manufacturer maximum interval specs which is based on optimum driving conditions which does not reflect reality.)

Frequent fluid changes = cheap preventative maintenance.

Brake fluid - every 2 years minimum
Clutch fluid - every 2 1/2 years minimum
PS fluid - every 3 years
Coolant flush and change - every 2 years
Engine oil - every 3500-4000 miles or 5 months minimum whichever is sooner
Oil filter - every second oil change.

2002 civic ex overheating


with your description it sounds like your fans are not coming on, also sounds like the problem was never solved, sounds like you threw a lot of money at your problem also... check to see if the fans are coming on at the right times, seems like a n air movement over the radiator since you say it only gets hot in stop and go traffic... well when your driving at a constant highway speed guess what you have air movement through the radiator... check also a clogged ac condensor with bugs, pressure wash it out so the air can pass through it easily... please rate my help thanks
