My 94 has the original radiator from what I can tell and it's starting to get rust and corrosion accumulation inside, no overheating issues yet. It's the metal rad. I'd like to do some preventive maintenance and get that scale flushed out before it becomes an issue. I'm aware I may spring a leak in the process but that's a risk I'm wiling to take vs a blocked and plugged rad. Anyone have a goto product or have any experience with thermocure?
If I do spring a leak I have a backup plastic rad that came with my truck.
