Car Leaking coolant

[MfrMadcat]

i fully built car, drove to flitari, got engine parts checked and tuned and such, put in racing rad, made sure all bolts are tight removed water pump and head gasket replaced them, and the satsuma still leaks coolant(only wen vehicle is running if you fill and not run it doesnt leak) iv resorted to msc editor and cant see anything wrong all wear items up to 90% ish nothing says damage true. out of ideas need help, i do have donner ecu mod installed

if you got the aftermarket radiator and everything is bolted on properly, it should work. I would suggest deactivating the mod and test if that's the culprit.

i have tryed that aswell and didnt fix the issue

I think it just drinks a little even at 100% mine always does anyway

[MfrMadcat]

mine will go from 100% to 30% in about a minute then stay there for around 15 mins then start lowering

tighten the hoses

Even after tightening the hoses and having the Racing Radiator, you will lose coolant. It goes along with losing oil and brake/clutch fluid. It's a feature, not a bug, meant for you to be constantly maintaining your vehicle.
