As above would it be ok to weld the boss for my mechanical water temp gauge directly onto the side of the rad somewhere? If so does it make any difference where on the rad it goes?

Cheers

no good on the rad as it will read different temp to what the engine is.

 

Had mine welded on the thermostat housing.

... and my Defi water sensor is in the bottom of the swirl pot.

 

Mine is in the top hose, got a proper fitting kit from Burtons.

My SPA one is in the original temp sender hole in the head

I also have a back up in the top rad hose.

 

defo no good in the rad!

 

Ok cool cheers, wasn't100% sure so thought id check! Mounting at the bottom of the swirl pot sound like an idea!

Have you got a put of how its mounted at all Steve?

Cheers

you want it engine side of the thermostat ideally chris, otherwise it won't read much until the thermostat opens.

if you're only interested in the hot temperature, then after the thermostat would be ok. in the rad would be fine if you put it right near the inlet hose which will be the same temperature as the outlet of the thermostat once it's opened fully. the further away from the inlet hose that you go either down or across will see the temperature dropping quickly

 

Ok so it may be ok to put in the rad right near the top hose then?! I'm not overly overly fussed about a 100% accurate reading, I just want to get an idea as to when its about to overheat

Chris

 

that'll do fine for that. you'll get to know what normal is, and then see when it gets hotter than that - unless it verheats because the thermostat is not opening

 

Sorry i ain't got a photo

It is a very nice bit of kit with a threaded bose for your temp sender, you just cut the hose and put it in the middle (you also have to cut the length of the hose down to fit)

It is very well made and was about £25 i think.

i found best on a CVH is the lower hose on the stat housing.

Put it at least 50mm from stat, and that stops heat soak.
