Coolent overflow... Need Help...

[headlightwashers]

ok... i have an 87mk3 with a JDM Engine and 3inch turbo back exhaust. and the coolent overflows when i park. Its not a BHG. cause there is a new one on there. the head is shaved and i have a higher compression so i have to run 93 plus a bottle of octane booster.. Its not a thermostat, cause i was just replaced, and its not the radiator cause it was just replaced. my electric fans are wired to a switch cause i didnt have enough money to get the temp sensor or whatever its called. so when the temp gauge (aftermarket) says 160, i flip the switch for the electric fans. and after i park the car some coolent still bubbles out when i have the fans on. i could only think of 3 things, 1. radiator cap is rated for 13lbs. 2. i need a fan shroud for radiator. or 3. i forgot what 3 was but ill remember if anyone has any suggestions... thanks

Are you runing 50% h2o / 50% ethelene glycol?

Are you runing 50% h2o / 50% ethelene glycol?

Also, are you allowing your engine to idle 30-60 seconds before you kill the engine after you've run it for a while?

i am interested in the answer to your question, my 88 turbo did it before the rebuild. good luck

Burp your system. Search around, there's writeups on how to do it.

For the love of god, man, buy a fan thermostat...
I have a Flex-A-Lite one that I'll sell you...

my bros car has the same problem and hes on the stock clutch fan. BHG job done not too long ago and burped it. it might still be a pesky air pocket and it has a new rad cap.... keep me posted guys

ok, for 1, how would i buy your thermostat, and 2 what would happen if i got rid of the engine fan and put some electric flex-a-lite ones behind the radiator? would that be expensive? and one more thing would the fan shroud that currently is missing have anything to do with the overheating at low speeds? but for now ill try to burp it. but i am interested in your thermostat.

That's what I got. It's used, however slightly...
PM for the rest.

you should definately get the fan shroud, i ran the stock clutch and fan with no shroud for a while and on the highway it's fine but any kind of stop and go and she would overheat at a light until i got back up to 45 or so, but once i put the shroud back in no problems since.

hope this give a little info for you

i was pushing coolant when i reversed my overflow bottles lid. Not pushing anymore coolant after fixing it.

Also make sure the hose that goes from the overflow out make sure its doesnt go below the bottom of the overflow tank or it could cause a siphon effect when fluid is pushed into the overflow bottle.
