87 Samurai. Stock with a weber
I have been having this overheating problem. I changed the thermostat and fluid + have a new radiator. I can't find a leak and see no white smoke of water vapor coming out the tail pipe.
i keep adding coolant and it keeps disappearing. the vehicle warms up and then goes into the high, and then back down(usually). When it cools off, I add more fluid and drive again. Pretty much the same thing.
I'm thinking that I have a headgasket going. As well, I think the water pump may only be working when it damn well feels like. Maybe the thermostat opens so late that it vaporizes the coolant? Do I try running without a thermostat? Should the water pump be noticibly cycling even when you just start up cold?
Anybody else go thru this.
What in the world is going on?
