Best bet is remove thermostat housing, drill and tap the bleed screw location to accept your temp sender and fit it there. Neat, tidy and accurate.
Bleeding the coolant on these engines is not the rocket science probematic experiance that people seem to think. If the bleed screw location is used for temp sensor then all you need to do when filling with coolant is to remove the small bore IACV coolant hose from it's outlet right next to the bleed screw. This will do exactly the same job as the bleed screw and is no more difficult to achieve.

Sorry to have to tag you again, I know you are always busy :oops: @PerformanceAutoworks But I could really use clarification on this.

What about using the place for the OEM water gauge sensor? Can I just pull out that sensor, install my own one and run it to my aftermartket water temp gauge? I assume the ECU gets all its info from the engine coolant temp sensor directly next to it, leaving the gauge sensor to only send info to the OEM gauge?

In brief.... yes you can sacrifice the OEM gauge sender and place your aftermarket temp gauge sender in that location.
It will have zero effect on how the car runs as all it does is the OEM dash temp gauge.
I don't usually suggest it as most people like to keep the OEM gauge working.
The thread is even the same as most aftermarket temp senders but obviously do make sure before simply winding it in :wink:

Awesome!!! Thanks for taking time to reply. Rep+ 8-)

I will deffo ditch the OEM temp gauge as it is pretty useless at showing temp, it only really does cold, warm, hot and I feel doesn't display the increments between them very well.

Nafe - Who knows :lol:

Newkid - It will save mucking about drilling and tapping. Plus If I don't have any confidence in my new gauges, I have bought the wrong ones. Oil pressure and oil temp are the most important two.

Co-incided with getting a hidden air-lock out of the cooling system? :?

Or in so doing you disturbed the ECT next to it and unknowingly sorted some problem with that?

That's the only thing I can think of. Must have been that... we'll say it was that ;-)

if your coolant temp gauge is playing up.. it will show on your oil temp gauge as it will be running higher than normal. so should be able to tell if theres a problem.

Hmm, I am thinking another possibility is the coolant drain bolt on the rear of the block. I have never used the drain bolt in my life so it would be a good location. I assume the sensor would get a good reading here.

Lings lists, what I think that bolt is, it to be a 28mm bolt plug (number 32)

What is the 28mm bolt plug equivalent in "M10 x 1.5" style?

I would have thought 28mm referred to the length, but the corresponding washer is also listed as 28mm. I do wish they'd use standard measurements with their bolts. If it was a standard metric bolt that would be an M28 and the thread diameter would measure 28mm, but that's a big old bolt! :?

Are you considering drilling and tapping it, or finding an adapter to screw straight in?
