The cooling system must have had a leak somewhere. Went to change the antifreeze and none would come out. The entire cooling system had turned to rust colored sludge. Went to have it suctioned out at the oil changing place twice. Didn't work.

Then took it to a mechanic I've known my whole life. He pulled the motor, pulled the freeze plugs and washed out the block. Then he sent the radiator off to have it routed.

DIDN'T WORK!

So I was out of a truck, and couldn't afford a lawyer.
