Q: I can't disconnect my oil coolant lines from under my truck

asked by on

It won't come disconnected

My car has 214000 miles.
My car has an automatic transmission.

Hey there. There are a variety of reasons this may happen. Sometimes when the lines are corroded or rusty, the fittings on the end are very difficult to break loose. Try spraying some WD40 on the ends of the fittings and letting it sit for a few minutes to try and break them loose.
