i had exactly the same problem with my 328 mate. the rad kept cool at normal driving but as soon as i put her to work she cooked within minutes. i would suggest changing rad and a decent bleed through as bmw's are prone to be a fucker to bleed through and i think you will be fine. i removed viscous and replaced an 12'' electric fan and keep it on constant and replaced thermostat and housing. since i did all that the car has been superb mate
had cooling problems on a 328 too, mine was a broken fan blade on the water pump (plastic ey) replaced for a metal one... replaced the termostat and added special higher grade coolant, bleed the system.. never had a problem again.... not the most expensive job.. water pump is arround 40quid and termostat arround 15 (make sure you have the metal housing for it too, some came with plastic)
big crash on NYE drifters still being fixed was loving it and got a little carried away, head on into a wall but got a new daily, got it standard and iv been playing... seems to have more lock as standard than the other one, oh well keep it fun day to day anyway the drift car is on the mend, got a new ac rad all in got a clutch, strut top mount and an engine mount on the way ready to get it sorted
It's a standard 323 so no racer but still nippy enough Got the drifter driveable ish it's struggling to idle at times sounds really rough, any ideas?
long time without updates, soldthe 323 got a 46 then went back to another e36 a 325 tds had lots of hastle with the drift car,after replacing thefull clutchsystem,master slave and clutch it finally works, and i started a pickup conversion here is where im up to... has to be ready late august for skids at teesside so should have some good updates soon planning banded steels, re paint and back to camo all over need to wind theback down alittlereplace the gearbox mounts then finish the bodywork, have a black cover for the back will be on soon and planning a vw caddy rear sliding window once funds allow
As well as the car drove on Monday I'm still having cooling issues, it got red hot after two laps and just never cooled down. It's got a brand new radiator from the ac version ( dlightly bigger) big aftermarket leccy fan and new coolant with the thermostat removed what else can I do?
