Coolant pushed through overflow reservoir (ser 60-14L- DDEC-5)

Mine was leaking out overflow tube. It is positioned to run out of itself. I ran it upwards immediately and then down and around. Haven't used any antifreeze since. We have ten trucks with same issue. 2 were radiators the rest were overflow tube in a crappy place

 

I have an isx that I have to put on a new pressure cap every 6 months.

Also, I put in a new egr valve and for a few days after it overflowed a lot.

It's been good for a couple of months now

I know this isn't answering OP's original question, but may be helpful for others.

 

I went thru this weeks ago. Please follow.
1. Complete Truck Srvs., Wytheville VA.
- You are loosing coolant either from a cracked EGR cooler or a leaking head gasket. we are not equipped. (Towing and minor repairs).
2. Triad Freightliner. Greensboro NC.
- You have a internal leak in the expansion tank. Tank and coolant replaced.
Truck released. Drove home. Next morning coolant down a gallon. Return to shop.
3. Triad Freightliner. Greensboro NC
- We are so sorry, found loose clamp and bad hose. Only charged for parts. Labor is on the house. Truck released. Hauled a couple loads. Adding 1/2 gallon coolant every day.
4. Virginia Truck Center, Freightliner Dealer. Roanoke VA.
- Pulled head as requested by customer. found leak between 5 and 6 and about to leak between 1 and 2. You are very lucky no damage to piston sleeves but the head is etched and needs replaced. $7061.00

 

If the coolant was pushing through reservour cap, might radiator or coolant filter. When last you change your coolant? If the head cracked or blown gasket, you should loose coolant. How much you were adding coolant? My friend had truck with coolant overflow, the reason was cloged coolant filter.

 

if you would use Rotella ELC or equivalent, change the coolant every 300k miles you would not have sunken liners for sure. sunken liners are typical on Detroit when owners don't change coolants.

the liner protrusion must be -0.0127-0.0762 mm (-0.0005-0.003 in). if it is less then -0.0127-0.0762 mm (-0.0005-0.003 in) you have sunk cylinder .
