Routine radiator flush n fill - info double check
So this is what wjjeeps says: (paraphrased)
"Recommended mixture is 50/50 ethylene-glycol and low mineral content water. Only glycol base coolant with corrosion inhibitors called HOAT is recommended.
If the percentage of coolant is lower than 44 percent, engine parts may be eroded by cavitation, and cooling system components may be severely damaged by corrosion.
Mopar Antifreeze/Coolant, 5 Year/100,000 Mile Formula (MS-9769) may not be mixed with any other type of antifreeze. Mixing of coolants other than specified (non-HOAT or other HOAT), may result in engine damage that may not be covered under the new vehicle warranty, and decreased corrosion protection. Do not use coolant additives that are claimed to improve engine cooling.
(capacity: 1999-2000: 13.0 qts.)"
So I'm planning to just drain/fill the radiator & distilled water w/ coolant as this is a routine maintenance thing and no issues exist currently such as overheating, heat, leaks, etc.
My questions are:
1. About the additive Water Wetter. I realize what wjjeeps says is prolly taken from the OEM docs. The additive claims to be compatible with everything and provides benefits (though marginal) I'm interested in. Any first-hand experience with their claims?
2. The HOAT I'm reading about as acceptible as Zerex Z05. Any counter ponts? Other recommendations?
