Re: Thermostat
besides the t stat what have you changed lately?
I installed an egr delete, 3 bar map, fuel pressure regulator, fuel gauge and a tweak chip. I have driven it multiple times when i get home from work on a few runs to get datamaster logs for eric at turbo tweak. I did all this about a month ago and never had any issues. Drove on parkway for 30 minutes to go see my brother and back home with out any problem. I did not beat on it the runs were more for idle and normal driving. If i got into 10 pounds of boost that was a lot.
I noticed the temp hit high on saturday when i was driving home from a meet. I was cruising about 75 mph on the parkway with A/C OFF. I had to pass someone and pushed it a little bit and got up to about 85mph. When i looked down at speedo was when i saw the temp gauge a little bit higher then half. My temp gauge since i have owned the truck has never left the line before half. I actually posted a thread showing how my truck runs cool a few months back. Last year i installed a heavy duty fan clutch, radiator flush, new hoses, new vac lines. . I really take care of my truck. Sometimes i think i go overboard.
Now yes the outside temp that day of the meet was hot almost 100 degrees but at that time driving home it was in the 90's. When i was driving to the meet i had A/C on just about the whole three hour drive and the temp gauge was fine just a little bit higher then normal but nothing to worry about and the a/c was cold.
First, how do you know it's at 200*? I wouldn't trust the stock gauge. I have a 160* in my truck and the stock gauge never gets close to that number.
With all due respect, you did put the t-stat in correct side up right? After that look for plugged radiator core. clogged AC condenser cutting air flow. Incorrect water pump, RH instead of LH rotation. collapsed lower rad hose. Only sure test is to remove and inspect.
What are your temps while just cruising at, say, 55 mph? AC on or off? Will it stay cool idling with the hood open and AC off? Some times these issues are related to hot air recirculating back to the front of the rad.
HTH a bit.
Don yes i did install the thermo correctly. The way the old one came off was the way the new one went in. How i knew about the actual temp was from datamaster. I had the laptop on my passenger seat. The temp went down to 190 when i was driving so thats why im thinking it might be the fan clutch. When i start the truck and its cold that fan clutch is loud and you can see it moving fast. About 5 minutes later it slows down that i can stop it by using a newspaper. After 20-30 minutes at idle and the temps are getting up there the fan will not stop it shreads the newspaper but its not moving fast like when i first start the truck when its cold. Weird...The truck can stay there idleing with a/c on or off and not over heat but get past half in the 205 degree temp which like i said my truck never ran that hot.
Put it this way there has never been a time that i have driven the truck and wasnt able to pop the hood and check the oil as soon as i get back from the drive. I came back from the drive this time and i went to check the oil and i burnt my hand. I dropped the dipstick. Thats hot.
I appreciate all t he help!!!:roll:
