Cooling help (moved from Bigger Radiator thread in Racing Subforum)

vendredi 30 mai 2014

hey guys I've never posted for help before on a forum but here it goes....



so i have a 2004 6spd, with 207,xxxkm original motor :O,



surprise, surprise it started to overheat, this lasted 2 days (about a month ago) I topped up the coolent and I was fine for about a month.



recently I overheated almost to "redline" on the dash gauge...



so I parked the car and went ham, I first found the nipple at the top of the rad to the coolent res had been previouly broken and epoxied on,,,, (previous owner) it was leaking so I installed a new rad, 2 (800cfm each) slim rad fans, moved the battery to the trunk (2.ga welding wire with 60amp fuse), put on a cold air intake, and a 78*c mishimoto thermostat. bled out all the air and fired it up...



at first the car refused to hold at idle and I had to keep my foot on the gas (1000rpm) it stayed running and the temp never reached "mid" on the temp gauge.



now driving on the highway she runs nice and cold and I did a dead stop launch from the shoulder on the highway and she took around 6-7 seconds



but... now at idle (rough 500-600rpm) the car starts to overheat like crazy (temp gauge climes rapidly)

(fans blaring) radiator is cool to the touch,



also just for Sh*ts i twisted the over flow hose up so I can see (from drivers seat) and found if I hold the car at 3000rpm its fine the second I let off the gas and allow the car to creep down to idle coolent starts jetting up through the overflow like a "geyser".





left over possibilities to me seam like,



1 water pump,

2 rad cap,

3 clogged cat, (defiantly clogged)



I run 93/94oct with about 8oz of 2 stroke at full fill.



I apologize for trying to hijack this thread but i couldn't start one of my own and im at my wits end trying to keep it together,,
