I bought a radiator cap from the dealer with the correct spec ( 30psi), coolant level went all the way down on the reservoir tank. - So it doesn't look like a bad cap issue
Next in the list- Radiator pressure test:
Went to autozone . None of the radiator pressure tester kits have a matching cap for BMW
I saw one kit at harbor freight for $80 . Anybody tried if this works on a BMW? - review of this product doesn't look good either. |
