that is ot how you test for a cooling fan problem and you should take it to your mechanic so you dont chop off any fingers. Those fans are on a special switch that comes on when the engine reaches a specific temprature. Paul, 38 years ago there was only one fan. Now, a lot of cars actually have two fans.
2) Propane contains an odorant similar to what's put into natural gas. If combustion is not complete, or there are any leaks, then this odorant produces a smell. In addition, in larger tanks typically there is a large tablet of solid odorant sitting in the bottom of the tank.
Why does my heater have a strange smell? Whenever I turn it on it smells like something is burning....it smells horrible...like how plastic burning smells. Update: I'll try leaving it on for more than a second...hopefully that will get rid of it. Update 2: Last time it was cleaned was six months ago.
