Tried changing radiator coolant yesterdy, but the stupid stuff wants to stay in! Warmed the car and took out the drain plug, just a trickle for 30 seconds and then NOTHING!!! Removed the filler cap, NOTHING! put everything back and drove the car for 10 minutes, removed drain plug..NOTHING!!! Finally unhooked the hoses and managed to get most of it off, still it took only 6 litres of new coolant, and the manual says 10.5. (yes...removed the bleeder valve) The temp gauge was right in the middle as usual. No overheating probs before or after. (just drove the car 44 k to work)
The last time I changed it, just took the drain plug out and the rad had a massive orgasm, not anymore. You think she's getting kinda old?
Me baffled....any help appreciated.
