New thermo put in, still not convinced its 100%
With my old thermostat installed, the temperture hand used to sit below the "L". The heater never worked either. Me and my dad flushed out the system, and put a new thermostat in, we put a 91* thermo. Now, the heater works perfect, warm and i was happy. But, when i start the car, i let it warm up for 10 mins, drive it, the temp hand goes right up aobe the N, then drops down below the L. Then driveing continously it goes up to the O, then to the L, and back and forth etc etc. As i keep driving it gets less and less bouncy. I did around 2 hours drving on the weekend and it bounces between l and M after the first hour of running. We put the thermo in correct, sealed everything properly, and we used the correct thermo to. Any ideas on what else i should try out?
