My oil temps are about the same in S+ mode but I have a Mosselman Oil Thermostat and a CSF oil cooler. If you have neither of those I'd check the oil thermostat.

Could you please advise on how to replace the thermostat ? I think that my coolant thermostat is failing and I would like to replace the waterpump and the thermostat together. Do you know if the fan should be removed first ? I had to remove it once, and it was quite a mess... Thus, I would like to know if there is enough room to remove the water pump + thermostat keeping the fan in place. Thanks for your help ! |

Do not have the remove the fan. Thermostat can be access from the bottom. 3 bolts and will require an extension to reach.

I will take some pictures of the process and post them for reference. Hopefully, I will manage to swap the thermostat and the water pump without major issues. Regards |

However, the coolant/oil temperature behavior did not change after doing a road test. Coolant rises temp until ~220F, time at which the fan starts working and it goes down to 180F. On road driving, the coolant stays between 170-185F on "Confort driving". The oil temp oscillates around 200-210F, when before, it was around 220-230F. I would say that my car is around 20F lower than it should be... Could it be that the coolant temperature sensor is failing? |
