Guys I am getting everything together to replace the oil cooler, egr delete. Do I need to replace the STC? It has 200,000 miles on her. Just trying to figure out what all I should do why I am in there...

Thanks
Daniel

 

First of all congrats on 200K! If you are that deep I would swap the STC fitting, Standpipes, and dummy plugs if you have the $$. Also flush the coolant and install a coolant filter if you haven't already.

Gauges are a must, I recommend Scan Gauge II.

I have a few pics in my profile that might help give you an idea what you are looking at.

Good luck!
