Any risk in swapping radiator caps?

[billschroeder5842]

Is there any downside to replacing my current 15lb cap and putting a 13lb radiator cap on the tank?

I'm thinking of doing this at the suggestion (dare?) of a couple of car buddies who think that it will help me eliminate the coolant seep around my heater hose (I did get the replacement part from Jerry's, and am waiting for it to "get worse") attached to the thermostat housing.

The theory is that the lower pressure cap will allow the hot coolant to escape into the radiator overfill tank, bypassing and not not forced out of the heater fittings.

I'm really getting only a modicum of seepage now and the thought is that going from a 15 to a 13 will allow the coolant to escape through a lower pressured area thus eliminating the seepage.

Sounds easy huh?

Before I swapped caps, I thought I ask and get a few opinions as to if thee is any foreseeable risk.

Thanks!
