Engine Temperature Sensor Location and Change

Crook90 · 2025-09-11 00:21:13

Hey all, so my engine temperature gauge on the head unit seems to be faulty. It doesn’t pick up the temp and then whilst driving after a while it will shoot up and bounce around after I’ve done a big drive. So I know it’s picking up some heat but it’s not consistent. I’m trying to locate it but not sure where I’m looking and second guessing myself when I think I find it. Also, looking for part numbers to replace the sensors. Any help would be greatly appreciated. TIA

On the 1.9s it's on the thermostat housing, just down from the fuel filter, the green and blue plugs below

As I remember it was one for the dash, and one for the radiator fans

Great thank you!!! Do you have the part number to hand at all, found one that looks right but always end up second guessing myself on this

Will this work for my van? It’s a 1.9 DW8 2000 plate

The part number appears to be

1338 A7
WATER TEMPERATURE SENSOR,
M12X150 2 VOIES,
GREEN

I can't see the part number on that page, but the thread size matches

That said, it says max temp 80? Seems low

Maybe check if the plug is the same as the one on your engine
