The reason for this little post is the reminder to myself that I have removed the Venatherm. A ‘what’ you say? A vernatherm is a thermostatic bypass valve that controls the flow of the oil to the oil cooler.

I am going to try using a water to oil heat exchanger instead of the usual air cooled oil cooler. The oil may then run at a higher temperature that the desired 180F as it will follow the coolant temperature. The maximum for oil is more than the maximum for boiling coolant under pressure so I should be just fine. The vernatherm would cut off the oil to the heat exchanger which might then overheat the unit, it just isn’t a great idea to leave it in.

I really hope this works or I will have to go old school and reinstall the venatherm. That might mean getting the engine off the engine mount for access after everything is installed.

It lives behind that big nut. I only have easy access with the engine off so now is the time.

This is what came out, then I detatched it and put the nut back in.

This was also the time you use that blue adapter fitting and install the engine oil temperature sensor. It is all now enthusiastically lock-wired in place.
