    Yeah, id be stunned if the thermostat fell apart, but FYI to anyone reading this, 160o is too cold of a T-Stat lol.

    I was unsure what temp to get and just took the one that they recommended at the store (160), needless to say I was back in their a few weeks later after my MPG plummeted since a 160 Tstat kept it from ever hitting operating temp, also froze due to really poor heater lol.

    Got me a 195 or so and its tons better

    When i did the flush i checked the T and it had no signs or cracks or weakness, the other night it fell apart in my hands.

    I have had the T go in both my 93 devilles, both times i wasnt at home either lol.

    Now that I've read that, I feel better about mine going (t-valve) in the middle of the day in 80 degree temps. LOL.

    Yeah, reading someone elses posts here can make you feel good. If you go to Northstared Caddies forums you will feel even better....

    Glad I could make someone feel good

    Now who wants to help me fix my breaks tomorrow?

    High will be 34 with a chance of freezing rain, oh and I dont have a garage lol


    Needless to say they wont get done, I will just use that car to jumpstart my other deville and drive it instead. The one with bad brakes is getting a whopping 12 MPG since the breaks are sticking real bad.

    Re: For those of you with coolant loss issues.

    I think karma made me pay for that LOL commit I made. My fuel gauge no longer flashes E (you know when you have one gallon left.) So I'm driving along thinking when it starts flashing E I'll fill'er up. (like I always do). Not this time I sputtered to a stop a mile from any gas station. I was able to use what little was there was to make it within 100 feet of the pump. So I'm pushing my car to the pump and some teenage blonde b*tch pulls into the pump in front of me. It was a fun day. Would anyone know what would cause your data center not to flash E anymore?
