This doesn't look right - cooling system

[Shugalou]

So I wanted to clean up behind the overflow tank before I do a flush and I noticed a couple things while cleaning all the grime off.

1. It looks like this connection on the rad has leaked and been repaired at some point...how reliable is a repair like this? I haven't really tested the truck out much since acquiring but it hasn't leaked from this location..although there was a fair bit of grease and grime around the area.



2. It looks these hoses at some point got put on over the pipes but it looks like there should be something mounted around this hole - as the rubber hoses are rubbing against metal - at the very least I will split a rubber hose to potect but I'm wondering what is supposed to be here.



Thanks guys

I agree with Chaplain. The lines are going to a transmission cooler and they ran them through that hole instead of making a new one.

It's hard to tell in the picture but the repair in #1 looks to be solder. If it is that is the best repair for a leak in a copper brass radiator. However, it can also be done incorrectly, but the picture looks like it flowed out and got a good bite into the metal. I wouldn't worry about it if it's not leaking.

Chaplain - Thank you for clarification on that one...It didn't even occur to me that the hole was for the air intake.

1774 Yeah I figured those hoses were for the trans cooler just didn't look right I'll have to find out where they are originally ment to go...it's not a hi priority to correct this (maybe if I upgrade the cooler down the road) for now I'll just put some rubber hose around the metal.

Burban thanks for the insight - I'll hold off on replacing this for now and keep my eye on it...When the time comes I think I'll put an aluminum replacement unit and upgrade the metal fan blade - I researched putting fans in and it gets pricey

Guys I really appreciate the help it makes me a little more confident to take this out and test it.
