The truck is a MACK CH 613, 2001 with an electronic engine E 7 TECH,
My problem is that the engine coolant tank explodes, because it grabs pressure because of the air bubbles. I already made sure that the pressure coming from the air compressor because it is being cooled with the same engine cooling system.
When I disconnect the water hoses, which are cooling the compressor I found that the air in the compressor chamber pass by the cooling ducts of the compressor therefore the engine cooling system receive pressure and this pressure makes the coolant reserve tank explode.
I already changed the air compressor and the problem was over. Also I already buy a new engine coolant tank but and after 1 month the problem appeared again and it broke my new tank.
I also check the new compressor and it does not pulls air pressure to the cooling system.
I also check that all the cooling parts are OK.
I would like to know which the possible causes are and if by any chance could we ask/answer in Spanish but if you can’t well there is no problem I would make the effort to try to communicate with you.
