    How is it done? Is the drop of water put on the engine cooling head or in the glow plug area? And how long should the count be for the drop to evaporate/boil off? 3 seconds? 5 seconds? :S

    the area around the glow plug is where you get an accurate read. it should take the water or spit a few seconds to sizzle off. if you put water or spit and it sizzles in a second, then you are too lean. but listen to experience and go with a digital temp gauge; less hassle and more accurate. save spit and water

    if you dont have the money you can do the spit/water but I just do it on top of the engine head it pretty much will give the right results

    tru but if you dont have much money the water test works just fine. The time is about 10 seconds or so

    10 seconds is a long time and may be on the rich side. the general rule is about 5 seconds for the water to evaporate but not sizzle. i have checked this against temp guns and it seems to be about right.
    hope this helps

    Having a 22.dollar temp. gun is cheaper than replacing an engine or a gallon of fuel. Stick with a temp. gun or borrow a friends.
