Been there, fixed that! Drill a 0.25" hole in the thermostat plate and all is good for using the upper hose as a suitable place for coolant temp sensing. I've used this scheme for 25K+ miles. YMMV as I do not know if this would significantly increase warmup time in a cold climate. Coldest temps ...

There's lots of ways to go about this and even some of the ones that you'd think would be less accurate (temp sensor in the radiator) can still work.

I was thinking of putting my Coolant Temp Sensor in the bottom radiator hose - so I guess that will work too.

But being in the radiator circuit ...

Thank you Matt, I'll go with a seperate sensor .

The attached diag shows the temperature sensor wiring on my Jag. Basically the +12v is regulated down to +10v then fed through the water temperature sensor and onto the temperature gauge. The sensor is the 1-wire type but I can swap that to a modern 2-wire sensor for better grounding.

Can I splice ...

I note from the manual that GM sensors are preferred but that it is possible to "map" your own sensors characteristics into the MS software. However I'd prefer to avoid doing this if at all possible.

Has anyone used any sensors off British sourced vehicles for IAT, CLT, TPS and Narrow Band 02 ?

We ...
