Paul.
thanks for your input, I don't have a engine check light on it, though I will have soon, it runs around 80deg's c that the moment ( all though I can change the temperture up-or down if I have to via a valve on the water flow) I'm running the factory computer, which is out of a manual supra.
Grant,
