ohhhhh GOT IT! =)

 

if nothin's workin man, i dunno what will. I really dunno whatz wrong.

 

sometimes when i look at my overflow tank its dry, so i fill it with water. then i look at it again a few days later and its dry again, so i fill it up to the max line again. i did this about 4-5 times. then today i looked at it right after i drove the car and it was completely full. is this normal? do you guys think two overflow tanks would help with the bigger radiator?

 

today i went to get a new thermostat. the guy at the shop said my radiator MIGHT need special coolent. currently, im only using the normal green stuff...he said i might need the pink stuff ( for my koyo alluminum radiator). do you guys know anything about this? do i need this "different" coolent?

 

Ok, here is a question. Did you install the new radiator because your old one was busted and you overheated or did you just replace it for the hell of it? [/B][/QUOTE]

i was just curious because you never responded to this question.

if you replaced your old radiator because you thought it was toast, and your car was overheating, maybe you have a differant problem. and having to add coolant constantly to your overfill jug doesnt sound right. that jug just lets the expanding water/coolant mixture overflow into it as the engine gets hot. my prelude has overheating issues too, but im 99% sure its something electrical. good luck though.

 

my old radiator started leaking. the overheating problem never happened with the old radiator. the weird thing about this is, it only does it when im driving around on the streets ..even at low rpms. when i took my car to an autocross a few weeks ago i was afraid it was going to overheat like crazy because i'd be driving it so hard, but it didnt.

 

Here is what I would try and why.

Because you're not overheating during auto-x driving, but you are overheating during in-town day to day driving. I would also asume you're not overheating during freeway driving?

If this is the case, my best guess would be that your fan sucks. Either its old and slow, or it's dead, or something. So here's how to check if it's working at all. Drive till you start to get too hot, and then pull over, leave the engine running and pop the hood, see if the fan is running. If it's not, then it's dead and you FOR SURE need a new one. Even if it is running, it may be running really slow and you might think about replacing it.

The reason I think it's the fan, is...that when you're driving, the wind from you driving your car is creating enough moving air to cool the water in the radiator, and therefore cool down the engine. But when you are driving in town, you stop at red-lights ect, and when you do that, the fan has to kick in and create wind to cool the water in the radiator. If it's dead, or slow, it won't cool the water enough and then the engine gets hot. I don't know if you have a new fan, or mounted the old one to your new radiator, but if the old one is now mounted perhaps it's mounted in a funky way? and is now binding on something? Just an idea...

as for the "special fluid" I've never heard of running special fluid in aftermarket radiators...call the people you bought it from and ask them. But I would bet the guy who told you that didn't know brake fluid from transmission fluid and doesn't have a clue.

Good Luck! Be sure to post up what finally fixes it! :-)

 

thanks for yer suggestion, but my car does overheat on freeways. i have my big fan hooked up manully and i have my other ( smaller) fan hooked up to the wire that USED to run the bigger one. my fan does sound alot quieter than some other cars i hear but i think integras just have quiet fans because my friends fan is quiet too.
