Starting to loose patients with......

My Heep.

Two weeks ago it's my e-brake doing damage to my drum. :banghead:
:repair: that, last week my auto off for the left turn signal has now become a manual off for the turn signal. (Since I'm not handy with auto electronics, I have to remember to flick it off now)
Today pull up in my driveway and smoke comming from under the hood. :explosion
All I see when I lift it up to check is coolant on the under side, all over the valve cover :banghead: There was so much of it spewed around that I could not tell which hose has sprung a leak. Upper rad hose or the upper most heater hose that goes to the water control valve. :doh:

What is the best method to test for a leak in a hose? If I don't give up on the heep first. argh
