R35 GTR: Time for a new thermostat

I know, I know, it’s not an exciting update, but it is a neccessary one! For the first time since I bought this car new in 2017, it’s needed something replacing rather than upgrading. The thermostat.

After a drive out with the better half in November, I noticed on the return journey that the car temperature was sitting at 56 degrees. I thought was unusual. The following day, I went out again and it sat at 60 degrees. It was a warmer ambient. I came home and scanned the car for codes, nothing, and the only thing I could think of is that it was the thermostat. So on the Monday I phoned Litchfield and was invited to bring the car down for inspection. They didn’t have a Saturday appointment till Jan 25th, which wasn’t the end of the world. I rarely use the GTR around December/January due to the attrocious weather we get here on the Mersey coast.

Fast forward, and I’m off to Litchfield in -2 degrees temperatures, doing 70ish on the motorway, temperatures steady at 58. I slow down and pull in behind a HGV. Temperatures increase 64 with the lack of airflow directly at the car. Better. I get some warm air through the vents.

Around 2 hours after arriving at Litchfield, I’m on my way. It was the thermostat, I’m a mechanical genius. And on the way home, I treated myself to some boost, some dump valve chirps, warm air and a few overtakes.

It’s still mega.

Back down in March for service and an MOT. Then it may be time to think about a new car?
