[@feeneysmechanical6215]

Thank you for the videos. Great job. Here's a tech tip for ya. If the driver says I have to keep adding coolant and I don't see it leaking. Quick test. Pull the drain on the air tanks. If coolant starts flowing from the air tanks. It needs a compressor

[@leanonme1065]

Which compressor? Can you be specific please

[@carlosa.garcia.9008]

Air Compressor.

I had sorta the same issue on my 2010 FX35... but when i drive all the coolant ended up in the expansion tank and out of the radiator... so often i had to siphon it back into the radiator. I didnt have any weird lights but if i continute to drive all the coolant will be in the expansion tank and myc ar will overheat.... after change so much i finally took it my mechanic where they found i had a warped head... changed headgaskets, timing chain, water pump, galley gaskets and all... all seems to have resolved the issue for now.... i'm still getting the air out the system after 195 miles driven.

Do the gas check

[@anthonybarksdale350]

I had pressure in my coolant and after running for 4 hours I was told it was my over flow reservoir cap. Then when I would get a load the pressure would spit out coolant through my hoses and split my passenger side top hose. So I ask them to change egr cooler and they found a crack in my head. My cam was damaged and rollers needed replacing.

[@TATEXPRESSINC]

Thanks for sharing your experience. A combustion gas test could of indicated an issue before hand.

[@johnvrbka570]

Forgot to mention checking the radiator cap. Even if its not mounted on the radiator but a coolant tank. Since caps are pressure releaf valves and need to maintain a certain amount of pressure to the system to lower boiling point since every pound of pressure raises boiling point like 3 or 4 lbs. If the cap doesn't hold pressure due to a bad seal then the coolant can boil out slowly. I don't work on big trucks but in the automotive business & I would say 70% of the caps I test fail

I have the isx 15. I’m losing coolant. But still trying to determine where. It’s going from cold max to cold min in about 16k miles. Talking with kenworth, I have no signs of a head gasket. No pressure in the coolant system. No cross between engine oil and coolant. Both look clean. No coolant coming out of the vent cap. No bubbles percolating in the reservoir. With a pressure tester it goes from 15psi to 0 in less than 10 minutes. Kenworth told me to check my fuel and transmission. (13 speed manual with heat exchanger) can’t see coolant in the fuel or water separates. I changed the transmission oil and sending it out for a oil analysis to see if coolant is mixing in it. I’ve taken the hose off the exit side of the egr cooler and looked good and felt dry. At this point I’m hoping it’s the heat exchanger on the transmission. It’s the cheapest fix. Other than that the truck runs like a champ and no loss of power

[@TATEXPRESSINC]

Have you tried pressurizing coolant system to find leak? If you suspect heat exchanger, remove oil fill plug to see if over filled

[@cztrucking1559]

TAT Express Inc. I did that over the weekend. Ended up draining the transmission. I bag some of it so I could send out for oil analysis. The oil looked like crap and I was 99% sure it was bad from coolant. But had no time and had to get back on the road. Well today it failed. Seen oil in my reservoir. So luckily I just got loaded and was close to home. I was heading for Washington. I went under and pulled to fill plug and oil looked like a milkshake. So picked up a new heat exchanger and came home. When I pulled the drain plug, coolant came out first then the milkshake came out. So flushing everything out tonight and back on the road in the morning.

Question:. I had front engine cover gaskets replaced, valves adjusted, rear engine seal replaced. I was basically leaking half a gallon of oil daily from front and rear. I never had any antifreeze preassure even when the engine was hot. Durning driving even on heavy loads on flat surface my antifreeze temperature usually stayed at around 180 even at idle. My oil temperature was usually at 200-210 regardless if on idle or driving. Now after the repair at idle or driving antifreeze temperature is at 200+-. Oil temperature at idle is 220. When driving under a 44k lbs load my oil temperature reaches close to 240 at times close to red line that's at 250. Antifreeze temperature stays at 200 and fan kicks in at 210-212F. And now when engine is hot I'm getting preassure in antifreeze rasivour which I never did. Before the oil leak repairs engine was hot I would open the antifreeze rasivour and I would never hear feal any preassure. What do you think the Russian mechanics messed up on the engine?

You have two key sensors, your intake manifold pressure sensor and exhaust back pressure sensor, those should be replaced yearly. Now, how about the DOC and DPF cans?

[@michaelwright1602]

More than likely you wasted that money on a new head, odds are a cylinder liner has broken loose and taken out your fresh new head. To see if this is your issue, drop the oil pane, pressurize the coolant system to 20 psi and let her sit overnight. Now, have someone get under the motor with a good flashlight while one of you bars the motor over by hand. If it is a slipped liner, you should be able to hear coolant gurgling in the head and will find traces of coolant on the cylinder wall, normally #5 or #4. Always do this test before removing the head, as these Cummins heads are pretty much one time use, and never use a remanufactured head, always new OEM.
