I have a series 1 rs turbo, the temperature gauge does not get hot it just stays on the cold all the time, the coolant is getting hot though,
could anyone tell me what colour the wire is to the temp sensor? I’m also going to change the thermostat, where is this located?

I'd change the sensor aswell thermostat housing is the right hand side of the head thermostat in thier it's easy to spot follow your hose to it

Roddaz

great thank you, would you know what colour the wire is that goes to the sensor?

Sorry mate long time ago I had mine cant say I needed to know I'm sure somebody will know and answer that one

There is only 1 wire to the temp gauge sensor on the front of the head next to the exhaust manifold.

If you earth that wire with the key on pos 2 your gauge should max out, don't keep it grounded too long though.

It might be a yellow wire, as smiley said been a while lol!

Just removed the thermostat housing, am I correct that the think rubber seal goes in, then the thermostat then the clip that holds it in?

GVK.

yep, is the seal ok? they usually go all goooey.

Roddaz

I’ve fitted a new seal

I had the same issue, changed the thermostat, despite several references to the pink/maroon colour the one that worked for me was yellow. But they do differ between cars.I tried different ones you can change the sensor without dropping the coolant , just need to be quick! Ensure to bleed the system properly, run the engine up to running temperature until the fan kicks in with the coolant cap off. Good luck
