Re: 350 Heating Up at Stops
A completely different possibility - I had an exhaust manifold leak apparently for some time - I didn’t notice it until the bottom of the gasket at the #3 and #4 exhaust ports had blown away/disintegrated/whatever and a quite audible knock developed when I would first crank the truck. During the time I had the manifold leak, the temp idiot light would come on sometimes when I stopped after the engine was at operating temperature...that hasn’t happened even once this summer since I replaced the manifold gasket.
