The saga of the Kodiak duramax rebuild continues. After warming up and all coolant leaks repaired and system holds pressure it keeps overheating. The theory is the impeller is slipping when it gets hot.

Keep them wheels turning:

How hard is it to change the front axle fluid on a 2021 Ford Super Duty? It’s not bad at all. The hardest part is getting the factory applied RTV sealant off the cover and housing.

To protect the surface we use plastic tools. I also use some scotch brite to get it nice and clean with lots of brake cleaner and compressed air. Be sure to not leave any debri behind. The bottom of the axle housing collects a lot of particles.

If it’s not recorded it’s not done. We use a label maker and also record it in the service manual.

How much of a pain is changing the rear differential fluid in an AWD Ford Flex? Well it’s not as easy as a standard rear wheel drive truck or SUV. You will need to vacuum out the liquid. Once you get it all out you will need to pump the 75W-140 back in. There was some wear metal on the magnet but not bad for 100K miles.

Sometimes you need a bit more muscle and Irv’s hammer can provide. After a bit of heat and lubricant she slid off.

People are always asking what is the best brake pads and rotors. These factory ones lasted 97K miles and they could have gone another 20K!

What’s leaking on the 2016 Ford Flex Ecoboost AWD? I can’t make this up. It’s the actual oil sensor. New one installed with a thin coat of RTV and we are as dry as an otter’s pocket.

I can see clearly now the headlights are on. We had a little haze on the Flex’s headlights. Instead of sanding. We just used some graphene polish with wool and foam and cleaned them up. The graphene will help protect them from the storm Az sun.
