    I have a problem with our 1999 STS. There is a coolant leak at the crossover where it connects with the front bank. I was wondering if anyone has any hints on best method to proceed? I have the time, and the patience, just want to make sure that I have my ducks in a row. I used dye treated...
  4. What is this part? picture included!

    Cadillac CTS First Generation Forum - 2003 - 2007
    So i discovered where I was leaking coolant, it was from the part pictured below. It would leak onto a hot metal pipe below and evaporate before it could hit the ground( which explains why i didnt have a puddle of coolant under my car). I want to replace this part but i dont know what the name...
  5. Bottomed Out - Advice Needed

    Cadillac Seville / Cadillac Eldorado Forum
    Took a trip today to an unfamilar area in the Cadillac. Google maps directed us to an unpaved road which I decided to take since we had already driven for an hour. Before long the unpaved road turned into more of a trail/path, with grass in between the light treads left by the few other cars...
  6. Feels like a slight mis in '03 STS

    Cadillac Seville / Cadillac Eldorado Forum
    Start the car up and it feels like my '02 Z28. You can barely feel or hear it but I take notice of these things. These things idle like sewing machines so hence my concern. I think there is a drop in midrange performance. Gas mileage is slightly suffering. Was going to check the plugs till...
  7. Coolant Smell?

    2004-2007 Cadillac CTS-V General Discussion
    I have an "05" and when i get into the garage i can smell coolant. I have checked that motor over and can't find any signs of a leek. I have only had the car for a few months so i dont know if this is normal for the LS6 or if I'm just lucky. Has anyone else had this problem?

    Cadillac DeVille 1985 to 2005 including:1985-1992
    I am flushing the radiator on my 1993 Sedan Deville. If I understand my owners manual correctly I should not be using the Green Antifreeze, but should be using DEX COOL b/c it protects Aluminum engines...can anybody tell me if that is correct? Also, I may have a blown head gasket and I ordered a...

    Hello, so 2 days ago My low coolant light came on, I topped it off, later that night the light was on and I had to add about 1-2 inches of fluid every time to the overflow container. So I looked under the car and can see a leak dripping off the transmission, I look under the hood and might...
  12. Coolant/Radiator Question -- 236 F Coolant Temp -- Taking to Dealer for Service

    Cadillac Seville / Cadillac Eldorado Forum
    After running my car hard (high RPMs) for about 10 minutes, the coolant temperature reached 236 degrees F. The photo below shows the temp. gauge over the half mark. Is this normal? Doesn't seem normal to me. Anyway, I'm getting the coolant changed tomorrow. I'm taking it to the dealer since...

  14. Need info/ideas - 98 deville losing coolant, not overheating

    Cadillac DeVille 1985 to 2005 including:1985-1992
    Been reading here for a few months, enough to know that the probability of my 98 Deville with 160,000 miles on it heading toward head gasket failure is pretty good. History: The engine has never overheated, but I wasn't sure of that until reading this forum. The highest temp was 230 something...

  17. Recommended Coolant Temp

    Cadillac Seville / Cadillac Eldorado Forum
    I have a '95 SLS, which does NOT have an analog gauge for coolant temp, just the info found on the DIC. This is the first vehicle I've owned without a dedicated gauge (I've added one to my '62), so when I read threads on what position the gauge is indicating (for example, anything past the 12...

    Ok so Ive posted on here before about my 1992 Cadillac Sts with a 4.9 overheating but recently Ive noticed that my coolant will start bubbling over even before the car reaches a high temperature (at around 90 degrees it will boil over) and shortly after this the temperature will begin to rise...

    99 deville , brought around 6 months back with 110000 miles, started having high temps in engine shortly after that. i noticed that coolant level comes down every alternate day, did not see any external leaks with engine running or puddles under the car. 2 mechanics have tried and spent around...

    Hello my fellow Caddy owners. I haven't been here in awhile since I guess I haven't had any problems. Well recently I discovered I had transmission fluid in my radiator and I did have this verified after I found what I thought I found. Heres the deal. I have replaced the radiator and have my...
