Trying to get my 6 back in shape, along with dealing with power steering noise, had the coolant warning light come on. Went to top off the coolant but the coolant cap is stuck. I can turn it the quarter turn to release the tabs, but it won't come off. Searched but didn't find any threads for an e24. I'm hesitant to force or pry it off, I don't want to damage the reservoir. Has anyone run into this issue that can offfer some advice on what to do, or what not to do? I didn't want to force the cap, unplugged the coolant level sensor and unscrewed the plastic nut it's in and filled the coolant through that hole. Coolant light on the control panel went off but came back on a few minutes later, maybe the level sensor is no good, maybe the connector.
The car is a '89 635, 33,xxx miles, has been sitting for most of its life for years at a time. Honestly the last time the cap was opened was likely over a decade ago, maybe even 15 years. I got it from the previous owner about 8 years or so ago, it's mostly sat under my ownership as well. Very likely with the exception of the oil filter everything under the hood is factory original.
Appreciate any tips or experience anyone can throw my way.
Well, I'd spray some WD-40 or similar under it.
Good luck,
Ray
Delicately, with a rubber mallet.
Push down on cap while twisting. I've had my 6 for 30 years and the cap has always been a tough one,
even with a new overflow and new cap.
Glad i was able to solve this so easily.
