Hey im kinda a noob with this motor so bare with me (coming from vw) i just picked up a e30 swapped with a m52 and i was driving it tonight and the temps just kept climbing and stopped before hitting red. i turned it off and it kept climbing up.. What should i tackle to make sure the temps stay in the middle and cool. fan clutch,Waterpump,thermostat?

Do you have a fan clutch? Most 24v e30's dont because of clearance with the radiator and opt for an electric fan instead. Maybe a dumb question, but worth asking.
How long were you driving before it got hot?
Did you heat up more sitting and cool down when driving?
Did you check your coolant level? -
Do you know what radiator and fan setup you have? Bleeding the system again is free so I'd start there. How about a pic of the engine bay that shows the radiator and the fan setup?For all things 24v, check out Markert Motorworks!Originally posted by mbonanniComment

First things first is there fluid in the coolant system?
If not raise front end ie on a small hill. Fill coolant system up with proper mix to proper level. Allow car to get warm ie need the thermostat to open to fill the system completely. Put cap back on check for leaks and so forth.
Do a drive check and see if it climbs again.
I see a fan so If you can put the shroud back on the radiator for proper air flow through it.Comment

Either that or swap to a large electric fan.Comment
