My 2001 Monty Ltd overheats predictably. If I start it first thing in the AM, it is fine. When I stop for an errand, and re-start, it will spike into the hot zone and stay there for 3-5 minutes before dropping back to normal. Also, when running hot, if I accelerate or climb a hill, the temp seems to drop.

Any ideas?

Thanks,Mike.motor has about 90K on it. Everything has been replaces except the radiator..new fan,Mitsu brand thermostat....I'm thinking blockage in the radiator...
