1998 Mack E7 460 blowing anti freeze out of overflow tank. Working on a 98 Mack that once it gets warmed up it pressurized the overflow tank and blows antifreeze out. The customer had it any Mack and they replaced the rear head and number 5 liner. The air compressor has been replaced along with the radiator cap.These systems are under pressure during normal use. If you have a leak in the overflow tank, or elsewhere, it can lower the pressure in the system and cause the water/coolant to boil a bit. Get the pressure back up (new overflow tank) and it will stop. The bubbling can come from a couple of things; it ain't normal.Just run the car without the cap on the rad until air burps out of the rad. Let it cool and then refill till you see a bit of coolant in the neck. You probably have some air trapped in the system that expands with heat soak after you turn off the motor. It forces coolant past the cap and then into the overflow line.May 13, 2014. 244. 1. 18. Blythe ca. Nov 27, 2016. #3. catman3126 said: let the pressure out when its cool, top the coolant off. drive it 30-40 miles and let it get hot, park it and checl the top radiator hose in the morning and see if its firm ike a tennis ball. if so pretty good chance your gaskets are done. time for studs.Leaking or blown head gasket. A frequently observed cause of coolant bubbling in overflow tank is a leaking or blown head gasket. When this component is compromised, combustion gases from the engine can slip into the water jacket and push air into the cooling system through the cylinder head.Elizabethtown, ky: Didnt want to hijack the thread below. we have a 2004 pete with an ISX 460 in it. today i drove it to the other farm and filled with corn, headed out to the elevator and it got hot and shut down, when shut off it began blowing coolant out the overflow on the radiator tank cap.During high speed fan operation, both engine cooling fans have there own ground path. The result is a parallel circuit with both fans running at high speed. The low speed cooling fan is commanded on when the coolant temperature reaches 108°C (226°F). It is turned off if the coolant temperature lowers to 104°C (219°F).A failed head gasket is caused by a cooling system that is no longer doing its job. For example, when a car engine heats up too much, the heat will cause the engine block and cylinder head to expand more than they’re supposed to, resulting in the head gasket failing. This allows antifreeze to leak into the combustion chamber, causing white ...I have a 95 f250 with a 460. I had coolant come out of the overflow bottle after sitting for a couple minutes.

If a head gasket blows, the combustion gases from the cylinders will leak into the cooling system and push the coolant into the reservoir. Once the reservoir gets filled, the rest will waste through the overflow outlet. liquid chris ImperialCrown. A coolant sample can be checked with a chemical CO2 detector. CO2 is a byproduct of combustion. If CO2 is found, it would likely be a head gasket combustion chamber-to-water jacket leak. If CO2 is not detected, it could be an air leak into the suction side of the water pump (lower radiator hose side).At about 55,000 i started having the coolant system blowing fluid out of the pressure overflow cap on the overflow container at random times. It started slow, having to add fluid every 1500 miles or so and has gotten to every 50 miles it’s giving me a low coolant level. All my temps are running normal.
