G-05 and Peak Global Lifetime?

[Crispysea]

I have a 2012 Grand Caravan, and I replaced the thermostat. I need a couple gallons of coolant now. I have some PGL 50/50, and G-05 concentrate. Can I mix the two, or do I just need to buy another gallon of one? Thanks.

You can mix the two with no problem

Great. I was thinking that, but just wanted to be sure.

pretty much the complete opposite in terms of add packs but no problems mixing

This van takes 3.3 gallons, so it would save me $40 or more to use what I have.

How much coolant do you have on hand? How much G05? How much PGL do you have?

I didn’t lose all of the coolant. There’s still air trapped in the system, though. I put PGL 50/50 in it the other day, because I was out of town, and that’s what I could find. I have a gallon of G-05 concentrate at home.

If you don't already have one, get a Lisle coolant funnel. It makes the bleeding so easy

It sounds like all the coolant in the car now is PGL. Is that correct?

The two are compatible and won't cause any problems when mixed, so nothing wrong with using one to top off the other, but if you're doing a complete drain and fill, you might as well use only one type of coolant.

I was looking around for the bleeding funnel. I guess I’ll have to order one online.

I realize you decided, good call to use it imo. Personally in a 12 Caravan I'd have no problem mixing G-05 with PGL.

G-05 is a low silicate OAT AF, no 2eha. PGL a full OAT AF, also no 2eha. Given that, I'd agree w/slacktide, no problem with compatibility.

As for air in system, only seen it once in older GM 3.4L Equinox (family member vehicle) with a China made engine, a pita to bleed. I never purchased the Lisle funnel, it 'might' help though. Squeezing hoses also a good practice. Apparently this is a common issue. If you haven't read link, might find it helpful. Seems patience is required too.

As an aside, never had an air in cooling system problem with Honda, Nissan, Toyota Tacoma and I've done full system distilled water flushes (d&fs) many times.

Good Luck.

I mixed distilled water and G-05, put it in, squeezed the hoses, and waited until the bubbles went away. I drove around for 20 minutes, and it never went over 195F.
