Fan switch and water pump

[jdearden]

Guys I have the part number for the fan sensor switch but what is the location of this?


Also need a part number for the water pump. For 2.5.
Cheers

If ur running MBE still and ECU isn't controlling your fans, then the switch is just before the rad on the drivers side. It looks like a sensor screwed into the metal rad pipe.

In the early days I went through loads of these so ended up putting a switch in so I could turn them on myself if switch failed. ECU controls mine now so I don't need to worry about it now.

I sent u text before seeing this post and mentioned that u need to get the metal upgraded pump. Ill check my build spread sheet to see if I logged part numbers. Did u look through wiki and Nobleparts?

Quick check on Nobleparts.

the switch fails because it end up switching too much current

a simple fix is to get it to switch a relay and let the relay switch the current

Sme1 has mentioned to me it could also be a sticking thermostat. Is there a thermostat in the mental housing just below the header tank?
Also anyone know what temp sensor I should be using for the temp gauge
