Around the mechanical or electric fan?
If around the electrical fan in the area of the lower hose check the nut that holds the lower tranny line fitting in.
Had a leak a few years back and thought it was my 10 year old Spectra radiator.
Then what I thought was a stupid idea popped into my head.
Put a wrench to that nut and sure enough.
Until then I didn't even know that was a thing.
My leak is mechanical fan side. But it only occurs when the overflow tank is at the full line. So this must be a pressure issue, still haven't found the source.
Update on the upgrades. The temps are noticeably cooler at idle, city and freeway, partial flush might've helped. The design for the radiator cap and placement is so bad I'd avoid this style / manufacturer completely.
The differential cover fixed my leak, and the lube locker gasket was reused. Anyone know an easy way to find a replacement bolt? Yukon only sells the kits.
Need to address some things with the suspension next, going to upgrade to ZJ tie rods. Then I need to future plan for a block swap.
