🔴 Enhanced Performance with PROTHANE 7-1714 Red Urethane GM Style Big Block Engine Radiator Isolators Review

As a result of using this product, I found that it actually caused more issues with my vehicle's cooling system. While it may have appeared to be a good investment for my automotive needs, it actually ended up damaging the engine block rather than isolating it.

Insulators needed to replace radiator in 1991 k1500. Took these for my large cooler (dual core) that I converted into my 5.7 truck. The floor worked well! But I don't have a large block cover so I had to reuse the original top mounts for now. Once I find the swamp block radiator shroud I'll let you know how the part fits together!

My original rubber bearings have deteriorated partly due to an oil spill. The urethane shouldn't rely heavily on oil so I think that would be an upgrade. My 6.2 liter diesel uses a GM big block radiator so I got them even though I didn't have sizing and other installation information. They almost work. They are the right size to fit on the radiator tank. The top ones are the right size to fit the top steel bracket EXCEPT the tab that is supposed to fit the hole sticks out 3/4" from the hole…
