Hi,

I'm concerned that my large Setrab 172 center-mounted cooler is keeping my oil temps too low. This is driving around in 60-70°F ambient temperatures in city or spirited canyon driving.

I studied how the auxiliary t-stat works and replaced my internals of the t-stat as well. I was concerned it was forced open. Now I'm concluding that the cooler is too efficient and I need to block off portions of it.

Another thing to note: I do not have an engine oil cooler; I have replaced it with an oil filter console.

Im getting about 155 F max at the lines to the entrance of the external t-stat now. I'm worried about continuing running the engine hard at these temps and I cannot get them any higher.

What is an elegant and reversible way to to block off the cooler to see if I can get my temps up?
