i,ve nearly finished my specialist components injection engine and come across a small problem. they've used the thermostat housing for the ecu water temp sender so i'm left with nowhere to fit a sender for a temp gauge. i'm not going to drill a tap a £1000 cylinder head so i wondered if a sender would work fitted to the top or bottom hose and would it be accurate?

In the top hose would be OK.

 

If you are thinking of using an adaptor like that ebay one, I'm not sure you'd have the space to fit it and you'll want a 25 mm one.

 

You could also have a fitting soldered in to the top tank of the radiator.

The thread for the sensor is likely to be wrong too .. metric usually in those adaptors .. and the one that comes with it will not work with the Mini gauge I bet.

In case this hadn't occurred to you: If you have your temperature gauge plumbed into the top hose, it's not going to give you an accurate temperature indication until the thermostat has opened and not going to give you the warning you need, if the thermostat doesn't open.

Just sayin'.

Only yesterday I made a spacer block for the thermostat cover and incorporated a separate sender in that. If I remember today, I'll snap off a couple of photos.

Same issue no. No flow until thermostat opens and then it is measuring the cooled water.

I am using one of these:

I had a shop put a port & polished aftermarket head on that had no port for the sensor.

This makes the sensor read a little cool, but still works to monitor overheating. Will only work if you don’t have a heater.

i used an mpi thermostat sandwich plate which has the hole and thread that matches the sc supplied sensor.

Good luck with the sc kit.
