98TJ Rotted freeze-plugs/Bad Antifreeze
My 98 TJ SE developed a bad coolant leak out a freeze plug in the head.
When I pulled over to investigate, an awful brown liquid was steaming
out of the block, I thought it was the head gasket. It was towed to the
dealer Saturday, now I'm being told the coolant is bad and the freeze
plugs and radiator are rotted and leaking. In addition, the water pump
bearings are shot. I don't disagree with the diagnosis at all, but I'm
quite puzzled.
This Jeep had a flush and coolant change about 2 years ago in the fall.
I can't understand what in the hell ruined the coolant so fast? I know
it's about due for another flush, but this situation seems really bad
considering the amount of corrosion, any ideas?

Re: 98TJ Rotted freeze-plugs/Bad Antifreeze
What kind of coolant was used?
Most of the stuff out there is the GM/Texaco Dexcool formula and it has
earned a reputation for causing the damage you describe.
DC directly states it should NOT be used in any DC vehicle
The only DC approved antifreeze is Valvoline's Zerex G-05. It may be hard
to find, I had to drive half way across the county to find it at pepboys.

All may not have been well even if the color looks good. PH is a major
factor even on the 5 year stuff most still need changing in 2 years.
