spazz97 Posted July 16, 2004 Report Share Posted July 16, 2004 Hey guys, About two months ago I got my 97 STS with 78k miles. Not two long after that I started getting a coolent level low display. Well I figured I might as well drain and flush the cooling system because who knows how long it had been since the previous owners had changed it. To my surprise, when I drained it, i saw that the coolant was the green stuff and not the orange dex-cool that the car was supposed to running on. So I went ahead and flushed and drained the car out about five more times and even on the last time the stuff still kept coming out green. Finnaly I said heck it and poured the 50% mix untill the surge tank got full. About a month goes by and I attempt to go up to Seattle and not even 10 minutes into the drive my temp needle started going up after i had to thromp on the gas to get ahead of a few cars going uphill to get into my exit lane. Then I got a "turn of ac for engine protection"...and so I did that and kicked up the heaters full blast. Well I kept driving and the needle didnt seem to want to go back down and hit the red or orange part of the temp and of course the engine went into limp mode untill I could reach the nearest town. As soon as i got it back into town I took it to the Cadillac service shop and told me that they were getting two different temp readings on the radiator it self. They werent really sure what to tell me other than I could start out by replaceing my radiator along with the thermostat and some hoses and they didnt recommend me rotting my radiator because the radiator in my car has the "plastic" tanks and that I could risk cracking them. Any advise??? I'm desperate. Isaac Link to comment Share on other sites More sharing options...
