Yes mine is a tb42. Don't have any heating issues, I only want extra power and improved fuel economy.
Anyway, I like the idea of using the existing ac fan wiring for the thermos, but mine doesn't work. If I bridge the wires where the sensor on the radiator is, it works though. But at operating temp, the thermo sensors resistance is open. Is this right? Or does it need to reach it's set temp to close the circuit?
The actual sensor thread is 16mm in dia and I've seen different temp sensors on eBay, which sensor should I pick? I've measured the temps on both sides of the radiator and the outlet side is about 20degrees C cooler. The lowest temp sensor I've seen is 75-80c, I may try this first and if I find the fans are constantly running, can try the next step up. I just hope it does run due to the outlet side on the radiator being a lot cooler.
I hope this makes sense.
