I have a feeling my radiator fans aren't going up to max like they used to when things get very hot.
The coolant temp sensor seems to be working normally and I had a new one put in when the radiator had to be replaced.
With the fans no ramping up as they should (I think), it results in the oil getting terribly hot and thin, and today I noticed quite loud tappet noise with engine hot. Oil pressure drops to 1.25 bar.
How is fan speed controlled? Is there any way to check if the fans are working properly?
