Saltings Posted May 29, 2021 Report Share Posted May 29, 2021 ok this is a get around on your rad cap there is a little metal disc that seals against the rubber washer get a small piece of a match or toothpick and place underneath to keep the metal disc off the rubber this will allow any gasses to escape into the top up bottle over heating is usually caused by an air lock from gasses this should cure the problem for now if in doubt pm your number Quote Link to comment Share on other sites More sharing options...

Maybe a possible intermittent thermostat fault if it passes a sniff test Quote Link to comment Share on other sites More sharing options...
