I have a stock 75 TR6. I drive it for weekend fun. She has been flawless for the past 2 years that I've owned her. This Fall after a routine 2-3 hour cruise I put her in the garage and the next morning I saw a LITTLE puddle of coolant on the floor. I checked the hoses and radiator and could find no trace of a crack or leak, no coolant in any of the cross members or other pockets under the hood. Recently on a nice afternoon I thought I would go for a ride. Within about 1 mile of home I noticed the temp gauge approaching the critical level and took her home arriving with steam issuing from under the bonnet. When I lifted the bonnet there was steam leaking out from the top of the water pump where the thermostat is located. Now my thought is that the thermostat is stuck closed or the water pump is caput. I don't think the radiator is the issue as no steam was coming out from the cap. The water pump belt feels snug. I would appreciate any thoughts on how to trouble shoot this issue. Many thanks in advance. /ubbthreads/images/graemlins/cheers.gif
