A few weeks ago I had to rebuild my oil cooler. Did a flush and changed all the fluids. Thought I was good and a week later my fan started kicking on once the engine was hot. I checked the coolant resivor and it was damn near dry. Added coolant and let the engine run. From what I can see none of the hoses are leaking. I'm wondering if the truck getting hot and cold blew the radiator? Anyone else think I need to replace my radiator? The leak is dripping from the middle of the radiator on the bottom.

Second question is wether or not this eBay radiator will work?

Positive it's dripping from the rad, and not the water pump weep hole dripping and splashing off the drag link/trac bar or crossmember? No cracks/leaks in the degas tank? Is the coolant system pressurizing?

I'm sure it's either the radiator or the coolant tank. I've looked all all over the fan shroud trying to find a leak from the resivoir. I plan to replace it at the same time I replace the radiator, if I do have to replace it.

Look inside degas bottle is there a diesel smell in there or black crud floating in the bottle?

No diesel smell but there's oil in the degas from the oil cooler issue

Injector cups or blown head gasket due to strecher bolt or cracked heads. Got a set of heads at the machine shop for that very reason

OK I didn't pressure check the coolant because I pulled the degas and seen it was in bad shape. I went ahead and replaced it. Filled the truck with water to check for leaks. Didn't leak so I drove the **** out of it. Still didn't leak. Turn the truck off to drain it and fill with coolant and that's when it started leaking. Coming from the passenger side bottom corner of the radiator. Definitely not the water pump. I'm left thinking it's the radiator. What do you all think?
