coolant
Hi,
I am planning to drain/refill the radiator on my 1994 SL2 auto. At my local auto store, I could only found those Prestone coolant that it touts for all makes and models. My Haynes manual specifically states that I should use non-phosphate ethylene glycol based antifreeze. I just so happen to have a couple containers of unused Prestone antifreeze, sealed, sitting in my garage for 8 - 10 years. Does anyone know would the chemicals in the antifreeze breaks down over time (again 8-10 years) even if it is sealed and kept in a garage all this time? Is it ok to use the coolant? Thanks, Ted |

If it says "safe for aluminum engines" then it's OK to use. 15 years
ago phosphate-free antifreeze was the exception rather than the rule. Do not put Dexcool (used in newer Saturns) in. > Does anyone know would the chemicals in > the antifreeze breaks down over time (again 8-10 > years) even if it is sealed and kept in a garage all this time? If the container hasn't broken down, then the antifreeze in it is fine. Tim. |
