about 3 weeks ago I started my truck up in the morning and the "low
coolant" light came on...then went off after the diesel warmed up. it did
it again the next day. then on the third day it would stay on all the
time. I know theres a seal leak, I replaced the gasket but that did not
fix the leak so I am waiting from some special "goop" I ordered from a
local dealer to come in...thats suppost to fix that problem. Anyway, I
filled up the coolant tank, about 1/2-3/4 gallon worth and the light still
comes on all the time, any ideas?
