Just started off with a Golf after having ford focus for for a couple of years. Yay
My golf car temperature has an issue which is that on a town run (keeping speed low ~30 mph). The temperature needle is set to 90 degree and its all fine.
When I take it on a highway or a motorway, the temperature sets back to about 60 - 70 degrees, that's doing almost 80 mph for about 20 odd minutes.
I have replaced the thermostat sensor but that did not seem to do much help.
I have had a look online and tried to check on how to replace the thermostat (having done it on my focus in the past), it can not be that hard.
When I looked into it to remove the alternator in order to access the thermostat, there is a pipe which I cannot seem to remove and it is made of plastic (I was scared to put any force on it as it might break).
Does anyone know what that pipe is (sits on top of the alternator) and how to remove it. I have added the picture, it is in the red square, the yellow ones are the screws which I already removed but there is still something holding the pipe. Please see the image
Thank you for reading, even the pipe name can be useful as there are not much tutorials for a BKC engine.
