Today, I drove the 5 ton on a 70 mile journey to the sand/soda blasting company and had a great trip with the exception of one problem. Since I have not had this truck out on the road all that much, I kept a close eye on the guages. for about the first 50 miles, the truck ran at 200 degrees. Two miles on down the road, I looked over and the temperature guage was pegged out !! So I started slowing down to take some load off of the engine (Cummins 250) , and the guage acted as if it didnt know where it should be. It "jumped" back to 200 and it seemed that the guage was bad. It wasnt a gradual drop in temp but a very sudden jerk from 240 back to 200. I kept my eye on it and the it jerked back to 240 and stayed there. I checked the water and it had plenty. I was able to squeeze the top radiator hose about halfways and it was hot. I need help troubleshooting this. Does it sound like a cooling problem or a defective guage ?? The water from the pressure relief petcock was very black and nasty. There was no pressure on it, it just sortof dribbled out of this petcock. Sorry guys, I'm no shade tree mechanic. First thing when it comes home is a radiator flushing. Hope that you can understand what I am talking about.. Thanks for the help.
