Tools needed to pressurize a COLD cooling system for diagnostics
Note: STANT 12030 threaded system testing adapter is required to
test most BMW and Land Rover cooling systems with a
threaded filler neck.
Images below are for a 3.0 application
As Andrew posted it not rocket science. Pressurize, look for drop in pressure on gauge, find source!
Oh, see #4 sensor in lower rad hose? The seals go bad all the time. You can either buy the sensor with the seal or just the AFTERMARKET seal. See Rockauto.com for the $.88 seal
