coolant flush 1998 aurora

[oldsdad]

Indy I have a 96 and it does have the sticker stating cooling system needs the walnut shells and ginger. Maybe thats so if you over heat it will smell like christmas and mamas in the kitchen making cookies and pies NOT!! I do agree with you Indy as to if its done right you shouldnt need anything but a good coolant mix and you shouldnt have any leaks. I put the tabs in mine cause they were free and I dont have enought time to do it over just do it right the first time. I figure that if they were there when they made the car and its still fine at 100k then it sure cant hurt when I change it.

You're supposed to take the thermostat out and reinstall the housing. Just don't forget to put it back after you flush

Yes the difference between Draining and Refilling. And Flushing is that the manual suggest removing the thermostat before Flushing.The manual treats them as two different procedures.

I am goin to do a flush and fill or a backflush. Not decided yet. But I had a quick question. The cooling system is VERY nasty. White sludge and just plain nastyness. I bought a bottle of cleaner for it. Does it have to say on the bottle if it is aluminum safe, or shoudl I assume it is if the bottle does not specify it is not ?
I have read a few of these procedures as far as the time and methods go. I was wondering if a simple drain and refill (even if for 15 - 20 mins) will clean out the system if it is really dirty. Or do I want to put a bottle of cleaner in there to de-gunk the really stuborn particulates ? Any other time I have ever done this, I have used a cleaner, even if I did not need it . . . maybe that is stupid, but I thought, its cheap and I cant hurt anything, only help. Any ideas or opinions welcome.
