Eltel54 Posted September 3, 2019 Share Posted September 3, 2019 I have audi a4 sport tdi 2002 I'm not a mechanic. I bought car 2 months ago guy told me there was a coolant leak at bottom of tank it's overflowing cut a long story short there's to much pressure in cooling system I've changed thermostat also put kseal in collant shortly after putting kseal in loads of foam in expansion tank. Could radiator be blocked car is now overheating but goes back to normal temp heater blowing hot and cold and losing coolant anyone have any ideas I'm puzzled Quote Link to comment Share on other sites More sharing options...
Magnet Posted September 3, 2019 Share Posted September 3, 2019 Hello, You will first need to get the cooling system pressure tested- and report back on the findings. One can easily jump to conclusions, but let’s wait for the result of that test first. K Seal? Not a good move, although I have seen some good results once, and with a low compression tractor! Kind regards, Gareth. Quote Link to comment Share on other sites More sharing options...
