overheating woes

Well first, let me say that I feel pretty stupid! I should have listened to.........Get this.....My wife! She has been saying this all along through my mis-adventures, that I need to replace my thermostat! I kept telling her that it was brand new and didn't need to be replaced. So I changed the pulley on the crank, I put a spacer on my fan to get it closer to my radiator, and I got myself a new 6 blade fan. Well all of those things that I did were probably a help, but today I actually removed said thermostat and put it in a pan of boiling water just to prove her wrong. Well, guess what? Yup, it did not work! So I took my red face out to my truck and went to the parts store and bought a new stat. Came home and installed it in the car and proceeded to drive the thing around for about an hour. And you know what, it did not even get to the first tick mark on the gauge! so I let it idle in the driveway for another 40 minutes and it finally got some heat out of the heater! So the next time my wife says that I should try something, guess what.........I probably still wont listen! Hahahahahahahaha PROBLEM SOLVED!!!!!
