I planned on getting a exhaust gas check kit from napa on monday morning.
Unfortunetly where I live there are NO auto parts stores that are open past on sunday, unless I want to drive 50+ miles.
After I test I plan on flushing complete system.
How do you go about pressure testing this system, since there is no access to radiator; only through the resevior which has no pressure?
Yes the truck ran flawless most of the trip...I threw a code on number #7 after 1880 miles but had an extra coil with; so a quick change and it ran fine. (from car wash; accidently sprayed to much water on drivers side engine compartment)
Yes, we put on a bunch of miles in a short time. We live in Northern Wisconsin and make deliveries all over the US.
Currently truck has 178,490 miles
Just an FYI: We pull a 25ft 5th wheel camper
