High pressure in coolant system???

Replaced air compressor and problem solved

 

Can you share with me your mechanics number and name in Sacramento?

 

FYI EGR exhaust pressure can be 60psi at full load , which is significantly higher than the cooling system.

The pressurization of the cooling system from an EGR crack will depend on the load....
It goes the other way too when the exhaust pressure drops lower than coolant and it's forced into the exhaust system

 

My 2015 Volvo has been throwing coolant leaks for the past 3 weeks 4 leaks 2 upfront 1 the def line and now one upfront again ??? Has anyone had this issue before can help

 

@kimone how many miles? Has the air compressor ever been replaced? A blown head gasket on the compressor will pressurize the cooling system. Also bad injector cups will do the same.

 

Volvo d13 or Cummins isx

 

d13 volvo

 

We had a new engine drop in in 2022 feb we havent had any rise in temperature on the gages but im not sure what the leaks about

 

We also had the compressor changed yes

 

The d13 has been problematic from day 1.
The injectior cups are a known problem...

Basically only 3 things will put that kind of high pressure like that.
#1 investor cups...
Shop can test this by checking if exhaust gas is in the tank, is the coolest gray or black..?
#2 air compresser head gasket.... watch to see if your getting more than normal water when you drain your tanks.
#3 head/gasket
