first try your thermo switch...maybe your fan comes on too late?

does it only happen at idle?

ATS*Mark

it only happens when its in traffic , then it kinda stays at the same temp when im driving the town....but goes down the faster i go......ya it looked lke it was comming on too late

i think your thermostat is workin....tryt wiring your fan to a switch so that its on all the time...if that doesnt work...my guess..its prolly a leaky headgasket

same problem here...i just ordered sum arp headstuds and an oem headgasket

im not leaking coolant thats the thing

Racerage1

when your gasket is leaking, it leaks exhaust gases into your coolant which makes it boil...and what happens next is similar to what u been noticing, get it?

i popped open my radiator cap and i had no coolant in there , i know for a fact i havent been leaking any cause i park in a garage , which leads me to believe maybe i have developed a crack in my radiator over the weekend(parked outside in the rain and cant see any leaks)

Thermo switch / fan switch or stop doing boostin burnouts in traffic !

Yup, I have a similar problem. Before my car is even warmed up (about 2 minutes after I start it up) my temp needle shoots the the very top H. Then it falls back down when I'm stopped, then shoots way up when I go again. hmm.

aahah when did i do that!!!!!

joecivic93

i blew my head gasket and coolant was not leaking on the ground.its goin in the motor and cooking off from the exhaust temps,replace head gasket and check head for warpage

I had a similar problem with mine too--after checking/changing all the obvious things--i swapped in a new radiator and its been fine ever since--older honda rads are prone to calcium deposits

joecivic93

i forgot to add in my first post that i also put in a new double core radiator it is not much thicker than a stock single core but has better cooling capacity which means the cooling fan does not have to run as much,at least thats what i was told!

the headgasket is brand new , only 4 months old.....and im getting no white smoke or anything , for some reason the coolant is being pushed into the resivior tank making it overflow!!!!!

my upper hose is hot hot , like too hot to grab and hold .
and my lower is just warm , i can hold it , does that mean my thermostat is gone??

CHECK UR COMPRESSION...MIGHT BE A SLIGHT BLOWN HEAD GASKET.....OR BLEED UR RADIATOR....TAKE OUT THE THRMOSTAT...=p TRY THOSE ...CAUSE IT HAPPENED TO ME...=T

mine did it too. i say head gasket. if its not ur thermostat.

ATS*Mark

i changed my thermostat to a modified one i had laying around , ill let you guys know if it does the trick

you might have air pockets trapped in the coolant system. check your fan to see if it come on after it warmed up.
