Thanks for the info. I probably will change the thermostat...I'm sure 200F is fine it'* just higher than what I am used to seeing.

Default Changing the Thermostat

Thats not usually a good idea.....The car is designed to run at a certain temp and not at a lower one. I've heard nothing but bad things from experianced mechanics about changing the thermo to a lower one.

Lee, and all bonneville owners 95 and above Vin# K engines. I also had this problem my car would not run below 200F and it normaly ran at 190-195F. Suddenly it started running from 210-240F and then the stat would pop open and drop to 180F , shortly after this trouble the upper intake cracked and had to be replaced,...The upper intakes on these engines are prone to failures, so if you have this engine always keep an eye glued to the overflow for coolant consumption.... 95 was the first year for the 3800 II V6 so I guess it could of had a few bugs

Ok guys, here is my 2 cents....I have a 95 SSE with a Series II 3800....I bought the car and when i got it home i could get no heat out of it and it ran under 100 degrees....I took it back to the dealer and had the thermostat replaced, and got the car back on the 7th day. On thenext day I was driving to work and white smoke was flowing from the exhaust pipes and the engine stalled...I had the car towed to the dealer and he investigated the problem. Seams the plastic intake cracked and leaked antifreeze into one of the cylinders. He told me that due to the high combution preasure some valves were bent and he could not get any compression in that cylinder. He replaced the motor with one that had 77,000 miles (or so he claimed ) free of charge. All i had to pay for was the tow to the dealership. My bonny had 97,000 on it at the time.

I was very happy with the dealer and was surprized that i didn't have to fight him to put the new motowr in. He even appologized to me for the inconvience. He only sells Bonny'* and SHO'*.....

Heres one for ya. #1 I swapped a 1998 series II non-sc engine into my 1995. The water pump is a 1998 the temp gauge is a 1995 the temp was se to the 195 that the 1995 were supposed to be at. LOL well I blew the gasket on the water pump. So I am going to get a new pump because you never know what is bad and I am putting in a new 180 thermostat with holes drilled. I figure this should help.

TY

My car always ran over 200, close to 225 or so in traffic during the summer. I popped in a 180 and ANOTHER tranny cooler last weekend. I can't break 200 at all now, and it takes a little longer to fry an egg on the blower now.
