Upper radiator hose. Coolant leak.

[Dm23]

Guys I’m having a hard time trying to figure out why my truck is leaking. I’ve replaced the rubber hose and tightened the clamp down pretty damn good and it still leaks. Anyone think I might have a crack in the radiator? Which is what I’m leaning towards.

It's probably split at the end tank

Clamps without a spring can cause issues

And it's hard to spot leaks in the finned area of the radiator. Some dye and a UV light will help you find the leak.

If in fact it is a bad/busted radiator, any brand in particular?

Factory is best.

OEM or Northern Radiator is all we recommend.

This may be a stupid question, but is it worth it to try JB weld if its just the plastic that is cracked? or not risk it and get a new radiator? The truck only has 120K miles on it.

The truck is 11 years old this year, personally I would get a new radiator and move on with life if it is cracked. To me JB weld or a similar fix would be a side of the road/I need to get home type fix only.

Could any of you guys PM me a price or prices for a new radiator if you guys carry them in stock? I’ll buy one from a vendor here if it’s comparable in price to other websites.
