Under the hood protection for water crossing...?

[GR8ADV]

What do folks do in the engine compartment, and other areas, other than a snorkel, for water crossings on an '04 taco? i see folks bury the hood on crossings. Is the battery under water, or...

thanks.

Use dielectric grease on EVERY electrical connection under the hood. On older vehicles people would seal their rotors with silicone to help keep the water out. Make sure your breather tubes for your axles are up high and if possible have a valve, and of course the snorkel.

Other than that, I wouldn't know what to suggest.

I've done a lot of trails in FL where the water was doorhandle deep in my turbo diesel Jeep and the only mod I did was a snorkel. My first trip in my 4Runner I went through a mud puddle and got a check engine light and the starter now has good days and bad (gets aggravated everytime I wash it as well). Since my CRD has been submerged more than once without issue and my 4Runner freaks out when water splashes on it, I've come to the conclusion that spark-infested motors are more complicated to make into submarines.

Gas engines have high voltage ignition systems which are more prone to shorts than the low voltage in a diesel. I've always heard that to set up a vehicle for deep water crossings, step one is have it be a diesel. ;-)
