My HQ 308 is overheaing?. Basically my guage will go up to 105 after 10 mins driving at around 2o degrees weather wise. Its all a bit strange. It will get hot then if I pull over urn engine off and restart temp will drop fairly quickly at times. It's like it's got an air pocket or something. Also when I turn engine off after a run guage will just rise going up to 110C. Got new radiator and Thermos anf 82 deg therostat. Put a thermo gun on it and temp on radiator hose, raditaor and water pump appears good. Highest yemp is eiher side and under the carby top of block, dont know wa hat means. Timing appears ok
Any clues.
