My 2015 Jeep Grand Cherokee only has 16,000 miles on it. It's still running the original coolant. It's going to be a LONG time before that vehicle ever sees 100K miles. (Which is supposedly how long the coolant lasts).
So... When should I start thinking about changing the coolant? How long does coolant last before it starts going "bad"? Is this newer stuff that great compared to the older yellow / green Prestone?
That's what my 1991 F-150 runs, and I've changed that coolant every 2 years. It's still running the original 31 year old heater core. And the radiator is close to 25 years old. So I must be doing something right.
My gut feeling is to change it out. But it's going to be a bit of a PITA to do it. It's not easy getting to the drain plug. And just looking at You Tube videos on the subject, there is talk about, "bleeding the air from the system"... (5.7 HEMI V-8)... Something I've never done on any vehicle after a coolant change. The air always seems to work it's way out of the system after a few heat / cool down sessions.
Where is a good place to buy this newer coolant besides the dealer? They rape you on everything. Or should I let it go for a while? It's been in there for 7 years.
