Opinions On Best Place To Get Water Temp From

[Shaun]

Hi,

Im installing a water temp gauge on my rb26, and im after peoples opinions on where the best place to put the temp sensor would be. Its a Greddy gauge, but im not interested in using the fitting that goes in the radiator hoses; ive made up a weld on using a BSP (pipe) thread. So my choices are:

- The aftermarket alloy radiator itself (on one of the tanks)

- The engine side of the top radiator hose (the aluminium engine outlet)

- The thermostat housing

Im almost certain that hot water exits the engine via the top radiator hose, so im assuming this is the best place for a water temp reading. Im just interested to hear other peoples opinions.

PS Where is the standard water temp sensor located???

Jeeesus, this is a hot topic! Dont flood me with answers.

Nah, seriously, i suppose it was a stupid question anyway. Ill just put it before the top radiator hose.

^^ lol, you scared them off with that intimidating avatar picture

Stockers are both in the top hose housing. I assume the single pin one's for the dash gauge, and the twin pin ones for the ECU.

I think its a case where Nissan got it correct from factory; IE, i cant imagine how doubling the motors output with all the good bits would warrant a sensor location change (electric water pump setups aside)

Silly Q: but why cant you use the stock locations? If you'd welded it up, I'd tap some holes in the same location, save you from using one of those gaudy top hose thingo's

thats all the jibber jabber i got

what about the standard aircon spot at the bottom of the radiator. thats what i was about to use

Yeah, i agree that i should put it in a relatively standard location, i just wasnt sure where the standard gauge temp was taken from. I assumed it was one of the top sensors on the engine side of the radiator hose, i just wasnt sure.

I dont want to use one of those adaptors shown in the picture, as i think they look shitty. Thats why im making up a weld on, and ill put it on the 'goose neck' thingy before the top radiator hose.

I feel like even more of an idiot after Duncan mentioned that the sensor at the bottom of the radiator was for the air conditioning! I had the sealing surface of that port machined and used a dowty seal because it looked dodgy on my china brand radiator. I could have just welded the thing up because i dont even have air conditioning!

Ill go now.
