V6 thermostat running temperature
Has anyone replaced the thermostat on their V6 with the latest batch of 'genuine' housings at all please?
I thought that the running temperature was 90 degrees C +/- 3 degress? The first one I fitted was running around 83. I've fitted another one and it's running around 81? I let the temperature build to 93 at idle, but it still fell to 81 when I drove round? |

Hello Ben,
Your running temperature should be in the low nineties when the car is moving. When stationary it may slowly rise to a maximum of 100 degrees. The specification of the thermostat is that it begins opening at 88 degrees +/- 2 degrees and is fully open at 96 degrees. Temperatures in the low eighties suggest that the thermostat is stuck open. I'd suggest that you change your supplier to a recognised X-Part dealer. Simon

Hi Simon.
Pretty sure I had. First kit purchased from E-Car parts, and second from DMGR's. Both marked up MG Rover. |

OK. I have no experience of DMGRS but I know that E Car Parts of Sandy, Bedfordshire is an X-Part dealer because I bought my last thermostat from them.
What method are you using to measure coolant temperature; the built-in IPK diagnostics or a third party device? Following your work on the cooling system, are you refilling and bleeding according to the official MGR procedure? Simon

Thanks for the replies.
I've had to bypass the oil cooler for the moment, as it's leaking oil into the coolant, but the thermostat would still control the engine temperature I would have thought? I'm using the OBD through the odometer, so the only other thing would be the temperature sensor, but it's not erratic. My blue ZT-T190 behaves perfectly. Stays pretty much spot on 90 degrees once up to temperature. |
