Something I whipped up to find a leak in my 2012 Caravan radiator (WTF, are these vans only made to last 10 years?). Bought a new one and the SOB leaks worse than the first! Have to pull it again and find the leak (low passenger side front i suspect. Plastic bullshit radiators, Ill get with the Amazon seller for a replacement. Only leaks under pressure so these plugs clamp on the upper and lower bungs and one has a Schrader valve to pressurize the rad. A few pumps with the cap on and a good ear will get you close. A squirt of soapy water will make any hole bubble. This one was split under the upper hose. I'll repair and use it for my break in rig.2x $5 1 1/2-1 1/4 tube couplers , 2 x 60 cent 1 1/2 knock out plugs and a screw in Schrader valve. Could probably use it on the vehicle too if you clamp one of the knock out caps in the removed upper rad hose and then the pressure cap on the open rad bung. pump it and watch for the leaking to start. The 13lb cap will vent before your rad balloons.
