EC's Going For It


For a while there 99% of our chassis had fresh virgin radials whether they were factory new or refurbished to new.

It seems like we've reached the timeline where there have been enough replacements so tire reliability is back to square one.
 
How my day started. I haven't found where its going yet but on the day cab it turned out to be the EGR cooler when it seemed to just disappear. Its not in my oil, it never overheated, its not on the ground, and its not anything obvious like a hose. I'm not even gonna fug with it. It's going to the shop.

I had my first suspicions about a week ago when I had to add about 1/3 gallon. Today it took 1.5.

Riddle me this: how can you have any kind of coolant leak or loss with a system still being under pressure at operating temperature?
Because it hasn't leaked ALL of the coolant out yet.

It's under pressure simply because it's being circulated through all the passages in the block, through the thermostat, the radiator, etc. It takes pressure to push it through everywhere it's gotta go, fast enough to cool a hot engine. That's what the water pump does.

Even when the engine hasn't even warmed up yet.
