Hi, anyone having problems with the operating temperature on 4 series Scania’s all 4 of mine are running at only 60 degrees, but when pulling up hill across Belgium/Germany/Austria they come up to normal 80 drgrees, but as soon as you are back on the flat they go back down to 60.
We have never had this problem before, I have spoken to Scania and shown them one of the thermostats and they said thats the correct part.
Anyone else having problems with low engine temps ?
I dont know if this is any help, but i have just replaced mine, as the temp gauge wasnt even moving when i was empty, but running at bang on 80, perhaps your thermostats are on there way out?
