Im sure the waterpump is faulty....Im getting that taken care of with the timing belt very soon. I have noticed that the car only overheats in idle...not on the highway. I have seen the radiatoro fan come on, however I have never see the engine fan come on.

I would like to start with changing the relay of the fan first, and then the fan if necessary.

what do I need, where is it located?

 

I just saw this post:

I left the car idling for a while with the AC on to see if the radiator fan would come on, and maybe after 8-10 minutes the temperature started to very slowly climb past 1/2...

Does the fan turn on at 3/4 right before the red (like GM designs their cars), or is it supposed to keep temperatures steadily at 1/2?


Heh! Let me tell you about Honda CiViC temp gauges...

Basically, they're glorified 'idiot lights' by design.

If you ever see your gauge go past 1/2 way, there's something seriously wrong with your car 'cause it'll take the fires of hell to make it move past that point.

The way it works is - 'C' at cold start up - 1/2 ALL the rest of the time. If it goes past 1/2 you got a cracked head, blown head gasket, exploded radiator hose, tossed belt, et cetera.

Bottom line: if you wanna see what's going on, you'll need to buy a REAL (accessory) temp gauge...

I have a 92 civic with 92k miles. All stock.(Even the timing and waterpump I believe) I have already bought the pump and the belt and all that good stuff to change... I have already gone through the process with my other 92 civic with 210k.

I dont think that I have a cracked head, or a blown head gasket and my car overheats only when it is idling. I have changed the thermo, and I am very certain that my waterpump is faulty and getting stuck which would cause it to overhear I would assume. I have also noticed that my radiator fan DOES turn on, but my engine fan DOES NOT turn on.

god I hate cars.

 

Its not that your water pump gets stuck its impeller had corroded to a point where it wont flow enother coolant standing still at idle

 

Sometimes the car will overheat when I am driving at slower speeds in traffic as well, like 10-20 mph, then when I push it up to like 50-70....or even just floor the engine for like 3 seconds it will "woosh" down real quick to where its suppost to be(or near)....Im guessing that the waterpump begins to move faster the higher the RPM's which would make sense because it has NEVER overheated at high speeds.

my car had that problem not to long ago. it was like that for acouple of days then after every 5 mins the car would start overheating. make sure there arnt any air bubbles in ur cooling system.

 

I have drained the coolant at least twice...I dont think this is an air bubble problem. It has been happening for about 8 months now. I barely drove it anywhere for the first 6 months, lately the past 2 months I have. Which is why I have bought all the items for the timing belt/waterpump change.

It sounda like a possible fan issue. At speeds over about 35mph the natural airflow throught the radiator is normally enough to keep the car cool. When going slower than that your fan is need. On a clutch type fan it will always turn but as the clutch wears out it will turn too slow to help any. On the Honda electric ones I do not know if there is a simular possibility.

Good luck

 

I think my main engine fan is not working along with the waterpump issue.

I have realized that if I keep adding coolant to the radiator, it does not overheat in idle as much as if their is none. I am guessing that the waterpump flows coolant through the radiator,and then from the radiator it goes to the engine? it would make sense if the radiator is fulland then the faulty waterpump doesnt always efficently flow coolant back into the radiator.

thoughts?
