Woolwax question: Anything to spray in engine compartment?

[JonMN]

Greetings set to Woolwax my JT for a MN winter. Watched a LOT of videos, but have a question.

Having the engine compartment so open to the road is tough on trucks. Does anyone shoot some of the exposed bolts and hose connectors? I have a small magnet pen I use to identify iron based steel, and most of the connectors and bolts seem to be. I was thinking I could give them all a shot of Woolwax, even though it will look like a mess. Still better than rust. Anything else I should hit in this area??

(You should see the bay in our 2008 F150. One winter the dipstick even rusted in place).

I used fluid film last year on mine. If I remember right about the engine bay, I think I just sprayed the top and inside of the frame rails, top side of the drivetrain, plus whatever hardware I could see without getting too close to electronics, engine accessories, or anything else that looked sensitive or got really hot. I also sprayed behind fenders/body voids/grille too where I could. Basically any nook or cranny where it didn't look like surface oils would cause a problem. I think I did under the hood with an aerosol can, vs the spray gun I used for the general underside.

Under the hood, I use Boeshield and/or CRC HD Corrosion Inhibitor, sprayed into a cup and then applied with a small brush. I usually try to do any exposed fasteners or brackets or other areas that I think may corrode.

Another great use for the CRC HDCI is the brake calipers. Brush it on when they are new. It certainly doesn't keep them from getting dusty/dirty, but it keeps the corrosion away. This is waht my calipers look like after 3 salty New England winters:

Funny I happen to have a can of both of those in the garage! Nice tip on the brake calipers too. I have been thinking of painting the calipers with the G2 system--have a few months to decide.

I used to paint all my calipers as soon as I took delivery of any new vehicle with plated calipers. I tried the CRCHDCI on a whim after I used Nyalic clearcoat (which failed in about a year) on our 2017 CX-5's calipers. Now it is my go-to, and I've used it on my JT and my wife's 2022 CX-5. It requires zero prep, and it is super easy to apply. I spray it in a cup and use a nice 1/2" wide horsehair paint brush to apply a thin coat. It is easy to touch-up if needed, although I've never applied anything other than the original application on my JT.

Two years and 30,000 miles. I apply a bit of lanolin coating once or twice a year and rinse off the belly here and there to keep mud from accumulating. All the roughness on the differential is just dust.

I regularly look through the frame holes and inspect the nooks and crannies for signs of corrosion and to date, nothing other than odd spots in the trailer hitch interface.

I’ve been quite impressed by how the truck has held up despite hard use. It’s absolutely been superior to my Subaru in this regard.

Thanks for the note! I am going to do this too. I really do not have a desire to change the caliper color, just want some protection. I can try painting them in the future if the MN salt it too much for them. Will paint the rotor hats, however.

My rotors look perfect after 3 winters. Whatever that silver/gray coating is, it does a great job. The only thing I do is clean them and (I know this sounds weird) apply Turtle Wax Hybrid Solutions Graphene Flex Wax to the hat area. This gets done Spring & Fall during my summer/winter tire change.

Under the hood, I usually spray inside the hood edge seams. Also take off the top grille/radiator support plastic cover and douche support frame rail and get into the inside fender corner.

Under the hood is a Catch-22. Plenty of areas that should be sprayed but you got to make a judgement call if it is areas your hands will go on doing normal maintenance and not wanting to get the grime all over you when you do it.

On my old BMW I used a product made by Wurth that is wax like and is quite durable. Unfortunately I can't remember the name. It seemed to protect the hoses, electrical and aluminum quite well.

I like to grease up my exhaust manifold before winter with a tube of good industrial grease, all purpose will do. Lather it on thick with your hands. Don't use gloves though because you want to really work it into the manifold and connectors/bolts. Use baby oil on your cats including flanges and bolts. If you see a little bit of smoke after you get to operating temp, thats how you know its working. Sometimes you can see a mpg or more difference in gas milage because the oils make you more aerodynamic. Like an Olympic swimmer shaving his body, the lube helps your jeep cut through the wind like an F16 fighter jet.

You're welcome.

Ugh, I gotta stop reading this site. I’m always getting things to do. Already have enough house crap to do.

With all that smoke coming off the exhaust. You looking like a crop duster downing down the road.
