dirty

I noticed my jeep would rarely, but occasionally heat up a little over halfway on my gauge. I checked my rad fluid and noticed brown gunk on the rad cap. My headgasket should be more than fine at only 100k km, so a coolant flush and replace will be in order. 12' JK .6L. Just wondering if theirs...

changed my air filter today. Looks like it needed doing. Not sure the last time it was done. Noticed slight reduction in fuel economy and thought for 13 bucks it wouldnt be a bad idea
