overheating m20

[heineck]

so when i first got my 325i i was told it had overheating problems froma bad waterpump. so i replaced the waterpump, thermostat, coolant temp sensor, fan clutch, and hoses. and my car is still overheating. and yes i bled the sytem with the valve on the t-sat housing. i can think of anything else that could cause my car to overheat, any ideas appreciated. :D

how long does it take to overheat/how hot does it get? does it matter if youre on the highway or not? you didnt mention the radiator so assuming all of the other parts are good/replaced, maybe look there.

yea new radiator too, and maybe 10 mins from cold start. its fine on the highway but when at idle or regular street driving its overheats to redline

i had the same problem with my 88 325is, and it was the sensor located on the radiator on the right side, i just put some electrical tape in it for now an rewire it. car is not overheating now, also u can check ur fanclutch.. good luck
