[Verdoro 68]

You’d think it was something bigger, but the remaining fragment of washer fits perfectly in the damaged areas of the radiator and there are some dings on the pulley to match the hood. As near as I can tell, it broke into three pieces with one staying behind under the bolt and two hitting the radiator.

I looked up the factory diagram last night and it’s supposed to have studs from the water pump and slotted nuts but not lock washers. The repro kits are sold with regular nuts and lock washers. What’s the safest setup to run?

I’ve been running grade 8 bolts and washers there for years without a problem. Here’s the funny part - I lost a bolt and washer when I was putting it back together. The only bolt I misplaced in all the times I’ve taken this apart! I picked up some replacements at the hardware store, but they were out of grade 8 washers so I grabbed grade 5 instead - guess what failed?

Fortunately Summit had Cold Case radiators in stock so I should have a replacement by Monday or Tuesday. I just don’t want to wreck the new one with bad hardware again.
