Ever since I bought this 89RX-T 4WD (ea82t) the temp. gauge stays in the middle during normal driving then when I get stuck in traffic it goes up to the red line but, nver over heats.
So, I replaced the thermostat and radiator....it still does it:banghead:
I figured since it didn't over heat it was the temp sensor. It's driven fine until ten minutes ago the temp gauge went all the way up and it over heated.
My radiator cap isn't even HOT!!!
I know there's penty of fluid in there cause the overflow bottle was at the full line.

What do you think it could be?
I'm guessing waterpump???
PLEASE HELP???

Have you considered changing the coolant temp sensor
(it's on the upper rad goose neck)
or maybe adding an aftermarket gauge to check the factory gauge

my car has a digidash, but when i have the headlights on, it is more likely to read high. I think i have a bad ground somewhere.
Maybe you have a similar problem.. do you drive with the lights on in the day?

Your digi-dash is notorious for faulty temp readings---both too high and too low. Best bet is to get an after market temp guage and install that.

If the cap wasn't hot, either the coolant wasn't circulating or there isn't enough. Don't trust the overflow bottle, the tube can get clogged.

what he said... when the car gets hot... it usually doesnt have ccoolant (or needs a radiator or thermostat) my guess is there is bad hose and the coolant has all drained out. Therefore the cap is cool because there is no liquid to heat it up. Replace ALL your coolant hoses. At this point in their life it is best to change em all. I have on EVERY SINGLE one of my EA82's and have not regretted it. They have run so much better since. :D

Ok I'll replace all the hoses.
After it cooled for a while, I put some water in, it took a good amount so I'm guessing I have a leak.

BUT, When I emptied the coolant out of the overflow tank(the tube wasn't clogged) The coolant was BROWN:confused: .(maybe oil?)

So, I started it back up and it idles low and rough.
Do I have a cracked block??

I now believe it wasn't the sensor, cause when it went into the red then past it, it DID overheat. :boohoo:

Ummmm my estimate is 12.... there are ALOT of hoses there... 2 heater hoses, the one that goes from the thermostat housing to the block (likes the blow), the one tha goes from the heater hose to NEAR the throttle body (likes to blow too), both radiator hoses, and MANY MANY MORE!

Oh, and dont trust your refill/resovoir bottle TOO much..... on my car it often was full and the system was empty... it depends on pressures and stuff.... I ALWAYS fill the radiator first from the raditor cap, bleed the system (start the car with teh WARM defroster on) then fill the reservoir after.

well when i bought my acura i had the same problem... it ran fine when movin, but when ya stopped it overheated... and the radiator was cold.. the electric fans never came on, even after replacing the thermo sensor...


i ended up having to change the thermostat, wire teh fans direct, and change a headgasket to fix it.. been good ever since..
