I just replaced my radiator and everything was fine until I drove it a few miles and now I’m having an oil leak. I checked all of my connections and they are all tightened. It’s a pretty good leak and didn’t start until after the radiator was replaced. Any help would be greatly appreciated.

 

Where is it leaking from? The oil cooler connections in the radiator?

 

Well i can’t really tell I can just see that it is leaking from almost the very front of the truck. It only started after I put the radiator in

 

Sounds like maybe the o-rings in the connections are missing or damaged. I don't believe the original radiator uses any o-rings (or at least any that can fall out), but some aftermarket ones do.

 

So what should I do? What would be the fastest way? I’m not using any power or air tools so it’s been a slow process

 

First, determine for sure where it's leaking from. You'll probably need a flashlight, and you may need to remove a couple of things to see (possibly the airbox or the fan shroud). Then, disconnect the line where it's leaking and figure out why (assuming it's leaking from one of the cooler lines.

Personally, I removed my oil filter adapter and bypassed the external cooler so I wouldn't have to worry about this kind of stuff.

 

Alright so I replaced the o-rings on the connections and now i still have loss of engine power it’s acting as if it’s in a higher gear at start

 

Did you check the transmission fluid? How much did you lose when you replaced the radiator?

 

I should probably check. Didn’t even think about it. I also just noticed the top line for transmission fluid is leaking a little. Should probably check on that as well

 

I really appreciate all your help Tom A. You are the man
