Hello All,

I did try loosening the bolt on top of the thermosat housing this morning before my commute to work. I removed the radiator cap and started the car and had the heater set to hot max temp and coolant came out of the bleeder holes in the side of the bolt. I did tighten the bolt by hand and let the engine warm up. After it warmed up I loosen the bolt with the radiator cap off and coolant sprayed out. I hand tighten the bolt and I filled the radiator (only needed alittle to fill) and put the cap back on. I loosened the bolt again and this time only hot air and a coolant mist came out the bleeder holes. I let it go for a minute or two and than the coolant flowed out in a stream. I tightened the bolt hand tight and let the car run for a few minutes. I than loosened the bolt again and hot air and coolant mist sprayed out again at first. After out 30 seconds coolant sprayed out in a stream. This time I hand tighten the bolt and than tightened the bolt with a wrench until fully tightened. I than relieved the pressure in the radiator by removing the radiator cap. I filled the radiator to the proper level. So off to work I went and the engine did not overheat and the heater blew hot air the 30 miles to work. ( temp gauge needle on O in normal once the engine heated up). I was glad and relieved the hole day at work. I checked the coolant level a few hours later and everything was fine. I left work 6 hours later and traveled another 20 miles and everything was fine. I was there about 2 hours and started my trip back home. Now I traveled 4o miles and had to make another stop. I was about a mile or so from this stop and I had got on it alittle bit and then the heater started blowing cold air and the engine temp started to rise to about the A in normal. (I said to myself what the heck is going on and a few more words but I will leave them out of this post.) I went into the store and was in there about 45 minutes and started on the rest of the way home. (about 10 miles left) The engine warmed up to the O in normal and I turned on the heat and it was blowing hot. About 2 miles into the trip the heater started blowing cold and the engine temp started to rise. So I turned off the heat and the engine temp took a mile or two to come back down. I turned back on the heat and it blew hot air. Then it started blowing cold again and the engine temp started increasing again. I turned off the heat and watch the engine temp decrease and I was home. I checked the fluid level a couple hours later after it cooled down a bit. Overflow is 3/4 full was about 1/2 way full this morning. Radiator level was 4 inches below the radiator cap opening. Thats 4 inches below what is was this morning. Very discourage at this point please let me know your thoughts. Thanks again for you help.
