Hi ive been refering to this site for a few months now. And id just like to say thankyou. I was checking all my fluids today and noticed that my coolant in my overflow was yellow and creamy. :/ so my question is has anyone had this issue. And what should i do/ look for. I just got this truck and really dont want to lose it. Thankyou

 

Does it smell like diesel as well? Sounds like you have cracked injector cup(s). I have never done them but they seem easy enough to change out.

Welcome to FTE.... Diesel Power Mag. just did a full wright up on doing that job in the newest magazine I got. I looked and didnt see a link on there site, you may want to keep an eye on it when they update it. Diesel Truck Engines, Performance Duramax Parts, Trucks & Cars - Diesel Power Magazine

 

This happened to my truck 4 years ago...Took it to the local dealer, and they said they found 4 out of 8 cracked. I had them all replaced. $1800.00.

Looking back, I should have asked to see all 8 of them.

Just be sure you completely flush the entire cooling system and remove all diesel fuel from the cooling system, you'll be spending more money if you don't.
