K Series Low Temperature PRT Thermostat (Grey, 78 degrees) PEL500110
If your temperature doesn't quite reach half-way or have overheating problems you can't pinpoint, you probably have a stuck thermostat.
This is a quality replacement for the PRT thermostat, and will restore normal functionality. This is a 78 degree thermostat, ideal for those concerned about their K Series running hot.
This is the 'grey' specification (78 degrees, soft spring) although the housings are Dark Grey in colour.
Please note due to variation in the production process, some will be almost black in appearance - but they are the correct 78 degree item.
The PRT thermostat was added to later cars as a measure to combat HGF - make sure you have one fitted to your car before ordering. You'll see it located within the rubber cooling pipes in your engine bay.
If you have the earlier system without this thermostat fitted, you need PEL10016 - click here.
