Hello again lads I've had my engine upgrade done for about 6 months now , my problem is the coolant hose to the Garrett 2871r turbo has split twice in the last week at the turbo end , firstly a hole which was fixed then today the pipe has split at the turbo lengthways as if there's a build up of pressure, engine seems to be running hotter than normal, heat through vents into cabin very warm. I was wondering if there might be an airlock any help much appreciated .
