Hi. Recently changed some pipes that should not have been on my van, someone had completely set the coolant system up wrong. Anyway it had been like this for the 2 years ive had it with no problems until i noticed how different my set up was. I managed to get the propper bottles and hoses as it had a vauxhall bottle and some unknown hoses. Whilst this set up was on my temp gauge never moved from the middle, but now after changing the set up the faster i go with more wind hitting my rad my temp gauge goes to quarter way up and when slowing or off the m way it goes to half way, if im strugling up hill it goes a little past half way. I just want to know if this is normal as i have never had a T25 or vw camper before. its a 1.6 d 84 panel van
Cheers steve
