There is coolant leaking from my 2007 Tacoma's radiator SOMEWHERE because there is leakage dripping from the lower right corner. I saw it when I took the skid plate off to replace the serpentine belt.
How do I test that the leakage is indeed in the radiator and not some hose somewhere with liquid just flowing to the point from where it is dripping? Can I disconnect all the hoses, drain the fluid, and pump it up (like a residential gas pipe) to test for fluid leaks, without actually taking the radiator out before I know it needs replacement?
At this point, my hopes are that the leak is coming either from the radiator or some hose and not blown head gasket. The engine gets overheated and the coolant resi tank boils soon after a fresh coolant/water refill, no froth on the dipstick or white smoke from the tail pipe, which would indicate coolant/oil mix and blown head gaskets.
