The blue thing in the side of the block, next to the socket. The engine was rebuilt and full flowed before my ownership so I presume its a temp sensor fitted at the same time. I have a remote oil filter head that can also accept an oil temp sensor, so also interested in any views on which position is more useful/accurate.
Brilliant, thanks for that. I don't have a wiring loom so I hadn't got as far as thinking about wiring to the oil light etc.
You can put the oil temperature sensor in the filter head . Will that engine have a doghouse cooler fitted ? Even if it has an off board cooler too , the doghouse cooler is useful as it can cope with 100% of the cooling at idle, then the offboard cooler can be smaller. In any case if you have an offboard cooler planned its worth fitting that with a thermostatic bypass valve so the engine warms up on cold days, and boils out the water in the oil.
Yes, based on your posts actually Mike. It has a remote oil filter with mocal thermostatic sandwich plate to a 12 row cooler. Will retain the doghouse cooler as seems to be advisable. Oil filter head already tapped for a temp sensor.
