That is the standard answer for a KZ owner
Just to explain and maybe a different outcome
My coolant is going somewhere.
I have had it tested at a radiator place. They did a pressure test and that chemical test to see if there is any exhaust gasses in the system and both came out positive. No leaks,but someone also told me you can not trust the test 100% for a diesel.Not to sure about that.
I also opened the radiator cap(when water was at working temp) and can not see any bubbles.
I am going to replace radiator cap and see. Must say there is some pink marks around the radiator pipe so maybe get some proper clamps
Also someone told me the waterpump can leak without seeing the water dripping.Again dont know aboot that
Any other suggestion or is it
