[C36IA] engine temp #2

Thu Jul 2 19:15:53 EDT 2009

Agree with all previous posts.  I did not take the best care of my new HX the first few years I had it and that was not good.  I was lucky to tatally save it.  Took it to a local radiator shop (Freddies in Bellflower for you locals) and they boiled it out, pressure tested it, totally cleaned it, stripped it and painted it with hear paint - thing looked brand new inside and out - $60.00.

I had the small elbow fitting of the out flow of impeller 90 % blocked with 
salt crystals. It was hard to find until you took it off and tried to get 
air through it.

| parts and the "fresh" water parts, though it sounds like the closed
| part.   Also don't ignore a possible air blockage.   Someone mentioned a
| stuck closed thermostat and that is also a definite possible blockage.
