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!

Pressurize the system. Any indy shop that has Volvos in and out will have the equivalent of a bike pump with an adapter that will fit on the expansion tank. 5-10 lbs of pressure on the system and it will be evident. Yes. a new part could be bad.

hmmm, i've done two new radiators on two different 850s, and never had a leak. Both Nissen, which is one step below Behr.
If an o-ring was leaking, you'd see oil or transmission fluid.
How old is the hose? It could have a tiny tear that is hard to see. Replace the hose, and inspect the plastic outlet from the radiator for cracks. I never tighten those with a wrench, only use a screwdriver.

Total brain fart on my part. The cooler is only oil or atf, duh. You're absolutely right. I was losing coolant from an old rubber hose which must have stretched or worn from the inside after i replaced my radiator...i assumed that the hose was on the radiator inlet for 6-7 yrs, and when i removed it, it must have cracked
Installed samcos and no issues since

unless the hose is newish, it's best to replace it. you're right, just taking off an old hose can create tears.
funny, i just double checked my radiator replacement this morning, the lower trans cooler was leaking! clip wasn't on right. I replaced the o-ring just in case, as getting that lower cooler on/off is a total B&&&CH!
