Let's say I go to a car show. If it's 50 degrees in the AM, the temps stay too cool on the freeway. Then when I go home when it's 70 degrees and sunny and it's fine.
Chas, If I remove and cap the cooler...I have the opposite problem...not good for Summer.
I have a tacky self stick clear blue vinyl that's used for covering metal. I can apply it over the
oil cooler hole and it helps a little, then pull it off when the day warms up (one time use of course but I have a big roll).
It's no big deal but I was wondering if anyone made a plug of some type. The problem is that the fins do get pretty hot to the touch, so I've been weary of putting something directly on them.
I can't say the motor is necessarily hotter but the Paxtons are a heat source themselves.
And you were right: roll on, roll off.
