Alright, so I've looked around and have done everything I can think of but to no avail...

Just a few weeks ago, I picked up a 95 Si, and everything has been fine.

The radiator was replaced a week after I bought it, and the only aftermarket part is a SRI.

When I'm at idle, after driving for a while, and sit for roughly 5 minutes or so, my fans kick on, and my gauge will start climbing. One bar every few minutes. I have checked out everything I can think of but no luck. The T-stat is new from Honda, and I'm sure it is working fine as both of my tubes are hot, meaning circulation. The fans both kick in, so I don't see a problem there, and like I said, the radiator was recently replaced and I've cleared it for air in the system.

Can anyone give me a last resort as I don't want this motor to cause me any problems till I get some money for a swap.

Motor is an h23a1 with 232km!

Thanks again

 

The gauge starts climbing after your fans kick on? Makes me wonder if the fans were put in backwards...

 

the way stock fans are mounted on 4th gens....it takes some fabrication to get the fans to sit backwards.

Are you sure ur fan is coming on?
when u bled the air from the coolant, did u have ur heater on?


My 94 does the same thing, and I just rigged the fan to turn on by a switch i mounted in the car. It hardly ever does it anymore, unless I really beat on it for an extended time, and then just come to an idle. On the highway tho...it'll drop to 1 bar on the dash, this highway cooling happened in July in FL wit the fan turned off. I figured the ram air effect would move more air than the fan

 

No, the fans come on like they should I believe, but just don't seem to keep the heat down. Both fans come on, as I've been popped the hood and waited, then they kick on, and a few seconds later I gain a bar on the heat gauge..

I didn't have my heater on when I bled the air...

 

I would try bleeding the system again. Have you tested the
actual radiator cap itself?

 

It could also be the temp sensor, I have a autometer gauge that tells me the temp and I have the one on the dash. Sometimes the one on the dash will say that the motor is hot when the autometer one says that its not... then when I take a laser temperature gauge and aim it on my block in different locations, the autometer one is dead on! I need to change the temp sensor but am waiting till I get a new radiator before the summer and just do everything all at once!

 

Also, check out all your grounds. A bad ground can lead to a faulty temp reading.
