Coolant leak developed on my 1999 Concourse while winterizing in the garage. Hoses were replaced spring 2022. Furnished hose clamps from Murphs found to be not tight and some coolant could be seen on a hose after one of them. Overnight after retightening them a new drip underneath the bike appeared. My next step is to obtain a pressure tester. Question: is the radiator cap a standard available size In a radiator pressure tester?
