Hello, car runs and drives pretty good. Can basically drive all day in traffic at slower speeds, but if I run a few miles on the highway it gets hot. I have flushed the radiator and tried two different thermostats. I now have a 160 in. It doesn’t leak fluid and the heater works. I can hear like thumping or bubbling in the dash it seems on the passenger side and the fluid boils after driving...really want to drive car to shows and stuff...could the timing have anything to do with it? Thanks
