New radiator in my 95 850NA...Behr. Two days old...there is antifreeze on the side of the unit, hopefully dripping from the UPPER hose (as opposed to a crack in a new radiator). I bought a new clamp, put it on today...still a wet radiator. Could it be a crack? How would I know? I am thinking that I will get a new upper hose...maybe the clamp just can't close it up enough...grasping for a cheap solution...Thoughts? Since the side has ribs, it is difficult to tell where the green fluid is coming from ... it hangs out on the ribs. DAMN!

 

If it is the hose or clamp, you should be able to follow the coolant to where you can see it escaping from the connection.

If it is the radiator, i'm sure your brand new part has a warranty?

 

Rinse if off with water. If the hose is butted up to the plastic tank loosed the clamp and move it back a bit so there is some room between the end tank and the hose.

The rest is up to you to be able to follow the leak to the source. If you really have a head scratcher you can purchase dye at an auto parts store to add to the coolant and use a black light to help track the leak.

There is always a chance you have a bad new part. Doesn't mean you bought crap as it can happen with something from the "dollar store" as it can from the dealer.
