This is a DIY video on how to fix the P026A code for secondary coolant system leak on your 2011 2012 2013 2014 2015 2016 F250 F350 F450 power stroke diesel engine. This intercooler leak or completely failed part is the most common issue on 6.7 F250’s especially if you have a tuned truck. I bought the replacement from eBay as it mimicked the mishimoto style air to water intercooler and it was half the price! We replaced it with a Mishimoto style intercooler from eBay in order to fix this air to water in a cooler leak. This is also a great 6.7 powerstroke intercooler upgrade for performance or tuned diesel trucks.

Another great thing to get upgraded on these trucks is the intercooler hose piping and they sell all types of good eBay kits. I plan on upgrading more of my F250 soon.

These sellers keep doubling prices so definitely comment with a new link if you find the same style for cheaper so I can add it here. The price is usually between $600 - $800 for this style on eBay.
