hi, on the cvh engine, whats the sensor on the thermostat housing? water temp or fan switch?


also if anyone has the plug that fits this sensor (also for the the fan itself) id love t buy them, need 2 or 3 of them)






cheers Jon

pretty sure that's the fan switch the temp sensor is the push on type fitting round the front of the bay can't help u with the parts tho

i think the water temp is the one on the head sticking out near the exhaust manifold, this also is missing a connector!

dont know what to do about this

[crazycage]

the one on the front is only for the gauge on the dash. the engine water tem sensor is on the rear of the inlet manifold

[mikeymikeyp]

just use a spade for the guage one

[jonyb4]

ooooh ah i see, cant remember if i connected up the inlet one...

s where is the fan switch?

and what is the sensor on the head near the exhaust?
its a small cylindrical 10mm sized jobbie with a push on connnector

The orange bit sticking out of the thermostat housing is your fan switch motorsport developments sell uprated meaning they bring the fan in earlier and off at a lower tempthan standard 20 pound delivered mine was for the rs the thin temp gauge wire that goes by the exhaust manifold can be bought off eBay also I think its about 6 pounds delivered

[jonyb4]

so can i just run a wire from that sensor to the dial and also to my ECU pin (as the XRTwo.com guide states)??

[rsturbonutter]

The temp wire goes to the dash mate. The one for ecu is white sensor I think? on the inlet manifold don't know if you can use that for ecu though

[Rhinopower]

They have to be seperate or they won't read correctly.

[rsturbonutter]

That's what I thought the one on inlet reads the inlet temp and the one for dash reads water temp in the engine itself is this correct

[AW0L]

That's what I thought the one on inlet reads the inlet temp and the one for dash reads water temp in the engine itself is this correct

from memory, there are 2 sensors on the inlet, the inlet air temp (side of inlet), and engine coolant temp (back of inlet by fixing bolts) (both go to ecu)

temp gauge sensor is on the front of the head as mentioned and either has a flat spade terminal, a round flat circle that a female spade will fit on or a round threaded pin type thing like the oil pressure switch has

[jonyb4]

AWOL i do love you

so if thats correct, the orange thermostat housing sensor is for the fan switch

great, just need some plugs/connectors for them now

FYI the water temp on the front for mine is a threaded type (like oil pressure)


daft that these CVH's use 2 different sensors though

[mikeymikeyp]

use a female bullet connector for that one then but a red one cos they are smaller and fit a bit better

[jonyb4]

to be fair, the colour (red yellow and blue) indicates the size of the wire end

[rsturbonutter]

And your point is? This is the size that's best fit to the size of sender thread

[AW0L]

of use an oil pressure one from a scrapper

[jonyb4]

Relax, just saying the colour changes the wire size not connecter end

[AW0L]

Jon if i have no luck with these plugs i found this, to help identify

page 7 top row connector 1,4 & 5

[jonyb4]

thats them, althouigh 5 differs to 1 &4 , the pins are on the opposite side inside

[AW0L]

ok, i will have a look, do you need pig tails or just the connectors?

[jonyb4]

pig tail?

[AW0L]

pig tail means connectors with length of wires

[mikeymikeyp]

to be fair, the colour (red yellow and blue) indicates the size of the wire end

I know that kid but for some reason they do fit a bit better

[jonyb4]

ah with wires deffo

if possible

[AW0L]

ok i will see what i can do
