We've had our 77 Kingsley just over a year and have changed all the fluid except the radiator coolant. It's still clean and tests to well below 0 degrees but we don't know how old it is. We're concerned about it's anti-corrosion and lubricating properties. We've read that Emery Stora recommends changing it I think he says annually or perhaps biannually.
We believe we still have the original steel radiator. Do both steel and aluminum radiators have anodes? And if we have an anode in ours where is it located and can we remove it for inspection/replacement without draining the coolant? Does corrosion or oxidation occur when the coach is sitting in storage or only when the engine is running?
Can we add an additive and, if so, what's a good one? Do they really work? We realize it takes about 5 gallons of 50/50 mix to change it but wonder if an additive might basically do the same thing.
We currently have a 15 psi cap on the radiator. Should we change to a 9 psi cap? What difference does this make?
As always, we appreciate the input.
