Just over 200k on our '05, went to get in the vehicle this morning, noticed a couple small puddles of anti freeze front left corner near tire on garage floor about the size of quarters. I popped the hood looked at the oil cooler lines going into radiator and low and behold where the upper oil cooler line goes into the radiator, the flange is leaking at the radiator side.

I don't recall many radiator threads here going bad. Some of you will remember late 2014, I replaced all radiator/cooling hoses. What a bummer, oh well I will get one on order, keep topping off the coolant, until I get the new one in.

What the real drag is my wifes daily is sitting in garage waiting on a special order upper radiator hose which which blew out on Saturday afternoon. It only has 52k on the clock!

Bummer man
I have over 200k miles on my 03 and so far I haven't had the radiator spring a leak(knock on wood) though I expect it to happen at some point

I do know the thermostat is bad(stuck open) and the heat takes 15-20 mins to work fully

What's the cost to replace one??
I am planning on getting a 2015 once they work the bugs out so I want to make this one last long enough to not need to worry about breaking down

Make sure the radiator is correct before you uninstall it. I almost made the mistake on a ford van they sent me a 2 core it was way too small and I would of had trouble in the summer driving with it in traffic

Some sound advise there!

I always try to make sure replacement parts are correct before jumping in and dismantling. Its a very good practice!

I did pick up a new radiator today from Advanced Auto. I may install tomorrow as the radiator did not leak in about 24 hours. Oh I paid $231.00 otd with 2 gallons of Dex-Cool.

Thanks for the advice fellas last thing I want to do is get the wrong one and risk possible overheating the engine
I am already risking it with a bad thermostat as it is
I know next oil change the tranny fluid and filter would need changing for sure

Just a follow up. I installed the new radiator from Advanced Auto last week. The install went fast and easy.

The new radiator even came with the locking rings for the oil cooler lines. It also has a petcock for draining. It comes with a lifetime warranty.
