Could it be?
I have combustion gasses in my cooling system, my radiator cap allowed coolant passed and covered my engine. any tricks or tips when replacing head gaskets on a 01 7.3 turbo.
Any ideas what else it could be, EGR, or is that only on the 6.0. thank ypu for any advice or parts info. Should i install oem gaskets? Are there better aftermarket gaskets? Thanks guys

 

Whoooooooo

Slow down.

7.3's with stock injectors rarely pop head gaskets... almost NEVER.

First thing I would do is check for fuel in your coolant, I would bet its a injector cup rather then anything else.

Compression check would be your first step.

 

howdy, I am sorry to sound like a foolbut i am new to working on diesels, i have been a mechanic for 8 years and have yet to wrench on a diesle. what axactly is an injector cup. thanks for your help and i am sorry for not knowing some of the diesle basics.

 

No sorry needed... Just dont want you to start replacing parts you dont need to...

An injector cup is pressed into the heads at each injector location. You use a bit of locktite to hold them and they seal the coolant from the injector and the cylinder... I dont have a cutaway picture for ya...

Look there...

 

Howdy,
Thank you for the help. Can I buy the tools needed to replace the cups for any specific place or does snapon or mack sell the tools? Thank you for the pdf with the directions attached. I am glad I dont have to remove the heads. Thanks again.

 

Howdy boys,
Can the injector cups be replaced with the heads on the truck?
