So add some more of the proper coolant (or some of the stuff designed to go with any type of coolant) to the overflow tank, there should be a cold and a hot line on the tank. Fill it to the cold line if the motor is cold or the hot line if the motor is fully warmed up. Realize this is the overflow not the actual radiator. Never take the radiator cap off when the motor is fully warmed up.

The excess reservoir has a radiator type cap on it, though. Would Prestone coolant work?

I'll have to check the tires. They say "80 PSI max" though and for reference, the ratings on the driver's door say "55 front, 80 rear".

Then all the fluid would leak out and ultimately cause the expensive transfer case to fail. When mine happened luckily I noticed the leak and fixed the hole with some JB weld which held up fine.

Ooh, Valuable information. Thanks.
There's more I'd like to reply to but it'll have to wait. I did read it though.
