HELLO GOLFER! is the car overheating.If so then the cylinder head has to be skimmed and checked for cracks. l am a mechanic and if you had come to me l would have told you that is standard procedure skim &check also when tightening down did you use the correct tighten down sequence and the right torque setting. if it doesn't over heat.Remove cap (when cold) let the engine get warm slack off top heater hose under bonnet and let the water bubble out without taking off hose wear a glove it gets hot. keep water standing by to top up rad.But if it does overheat then its skim & check and do it again.
