Coolant Flush - GM Engine Coolant Supplement ??
97 SW1 177,000 miles, 284,853 kilometers.
This car was due for a coolant flush. According to the owners manual, DEX- COOL radiator fluid only needs to be serviced once every 5 years or 100,000 miles. The last coolant flush service was done by Saturn 5 or 6 years ago. This time I went to an independent shop, but I brought my Owners Manual along. While I was in the shop waiting room, I read in the Owners Manual on page 283, "Use GM Engine Coolant Supplement (sealer) (GM Part No. 3634621 with any complete coolant change". I never heard of this before. The independent shop guys never heard of it either. I had the coolant flush performed at the independent shop. I got home and checked the Chilton Manual and the Chilton Manual doesn't make any reference to special "Engine Coolant Supplement (sealer)" in the coolant flush procedure. The Saturn dealer wanted USD $135.00 + to perform the coolant flush procedure. The independent shop wanted a little over half of the amount Saturn wanted for the same procedure. Do y'all think the "GM Engine Coolant Supplement (sealer)" is really worth the extra $50 to $60. Thanks for the help, SW1 |

Coolant Flush - GM Engine Coolant Supplement ??
The coolant supplemental sealer are two tablets that need to be crushed into
a fine powder and then added to the coolant after a flush and change. They can be purchased at a local Saturn dealer. If I recall they are between $5 and $10 for the two required. As to using Dex Cool coolant, I stay away from this coolant and continue to use the old ethylene glycol stuff that is sold at the Saturn dealer. This requires changing every two years, but does less damage to the radiator, water pump, etc. Good luck!

Coolant Flush - GM Engine Coolant Supplement ??
Thanks for the information on the supplemental sealer. I'll
get those tablets next week. I hadn't heard of DEX COOL damaging the radiator, water pump, etc. Another independent shop advised me to use the green ethylene glycol fluid because they were seeing damage to gaskets and seals from the DEX COOL. In ten years time, I haven't had any issues with gaskets or seals or radiator or water pump. Do you think I'm pressing my luck?

Coolant Flush - GM Engine Coolant Supplement ??
Appreciate the tips on DEX COOL -> aluminum engines, and
coolant supplemental sealer -> upper radiator hose, and shorter service interval -> fresh corrosion inhibitors/ph levels. I probably need to look at another independent shop, one that's heard of GM Sealing Tablets. Difficult to evaluate these shops until you get burned, and then you know it's time to find another independent shop that hopefully won't be worse than the one you got burned at. I sure could use some kind of litmus test to judge a shop. At 177,000 miles, even with regular 3,000 mile oil changes, my engine is a big question mark. Don't know if it will last 250,000 miles.
