Bumping this thread with one more question. I am going to install a low temp thermostat to try and get my 986 running a little cooler this summer. (And because of the many recommendations to add one on this forum.) It looks like I should be able to clamp most of the coolant hoses, and do the install without having to replace all of the coolant again.
My question is, what is the shelf life for coolant in an unopened container?
I just found a brand new, unopened gallon of Porsche Coolant in my garage. It must be from about 7 years ago. While in the garage it has been exposed to temperatures from about 100° F to 32° F, but it is unopened so I am hoping I can use it to top up after the thermostat install. Or should I dispose of it? (safely, of course)
Thanks!
