mix up a bucket of soapy water, get a broom handle and tape a piece of 3/8 clear hose to it , suck up some soapy water using your mouth on the hose, use the stick to reach into spots, like under the cab, and hard spots to reach , and blow some soapy water on your connections , watch for bubbles, its worked for me trying to reach under the cab and hard to reach places,
