excess engine heat
 

I have a 88 crx with a ZC swap. I am having problems when it is hot out with my car missing above 3000 it feels like it shuts off. I think i am having a dramatic amount of heat in the engine bay. is there anyway to cool this down? Would a old clogged catalitic converter do this? alos my car runs at normal operating temp the entire time. Just when i open the hood you can tell it is too hot...it is strange seems like the exhuast manifold is WAY to hot.

what does your water temp gauge say? did you bleed the cooling system? how hot is hot when you say it is hot outside?

Re:EXCESS ENGINE HEAT
 

80give or take a bit degrees outside......the engine tempture is runnign fine....about 3/8 of the way up....wamrs up and stays there never raises. If i open the hood it feels about 4 times hotter then if i open the hood on my S2K like the hottest car i have ever opened the hood on

if it's cool out, and you can easily go through the rpm's, I don't know if the cat would be the issue.. can't say much else, I have no idea..

i am thinking that the cool air keep the engine bay alot colder......thats my only thinking behind it..... :(

ordered a high flow cat today...i figured it cant hurt and it was 25 bucks!

Re:EXCESS ENGINE HEAT
 

have you checked the timing?

Re:EXCESS ENGINE HEAT
 

id say its the timing. if your timings off your egt will be so high it can clog your cat up. my freind timing was off and it melted his o2 sensor tottaly off and destroyed everything in his cat. check your 02 sensor and ---- like that. i realy doubt its your radiator.

Re:EXCESS ENGINE HEAT
 

oh and i wouldent put that new cat on until you get your timing checked and get a new o2 sensor or youl just burn your high flow one out as well

thanks for the advice the timing is right on the money, How can i tell if my 02 sensor is good? it doesnt seem to be running lean or rich. i checked radiator fluid it all came within spec (i work for a lab that analyzes stuff like that). i really think it is the exhuast manifold that is doing it. Would it be worth my time to wrap it in that thermal tape ---- people do sometime with tubos and whatnot?
