What is an expert oppinion on a subject of modifying viscous coupling so that it turns all the time. I live in Notrh West and the temperatures here are hi almost always. i am aware of drawbacks in the cooler climates but here seems to make little diference. A lot of station vehicles are modifyed in this manner up here. I am on my third coupling in 2 years now ......what are the options beside fitting electric fan.

See if it has screwws around it. if it has , I stripped
mine and washed it out with turps and then dried it, after which I added three vials of genuine Toyota silicone oil at $10 a vial. Toyota recommend two but I find that with two they are borderline. if you add three then it gives that little bit more drive while still allowing slip for river crossings.
Mine runs like a dream temp. wise now.

Dont know buddy. Take a good look at it and if it has some recessed screws around it then it is serviceable. A warning though, I had to get a pair of vice grips on the screw driver to get the screws undone. They are one tight mothers. Figured that was a gentler option than an impact driver. Good luck hope it works for you.
