ISL9 CM2350 EGR issue

[Luckyjayb]

The exhaust isn't the issue. The truck, a fire apparatus, is demandated and the egr cooler has failed. The city wants to keep it on there for appearances but bypass the coolant section of it since the egr isn't actually working. I didnt know if they made a pipe for to bypass the egr cooler on the coolant side like the isx and x15's. The exhaust side is closed off at both ends like it should be.
