edc Posted November 12, 2023 Report Share Posted November 12, 2023 You probably just need to bleed properly and refill whilst doing so. Quote Link to comment Share on other sites More sharing options...

Run up to high temp, indicated by the cooling fans kicking in which takes some time, with the car horizontal or slightly nose down and the bleed valve open, which is located under the panel that has the oil and water fillers.

Daboy3000 Posted November 13, 2023 Report Share Posted November 13, 2023 I thought I had leaks after a coolant change. Twice it did leak from the header area. Kept refilling it until it stopped. Hasn't lost a drop in months now. They are really bad for air locks. Quote Link to comment Share on other sites More sharing options...
Fat Rat Posted November 13, 2023 Report Share Posted November 13, 2023 Mine had just had a coolant change before I bought it. Kept burping for a couple of months before it stopped. Just topped it up every now and then. It is a bit concerning as the bottle was nearly empty the first time. No leaks or piddling on the floor after runs and no overheating. Just an awkward system.

charlieboy2608 Posted November 13, 2023 Report Share Posted November 13, 2023 It also helps when filling the system to have the header tank up high so either jack up or drive the rear wheels onto ramps. Quote Link to comment Share on other sites More sharing options...
