I just picked up my '89 BJ74 and had some general questions. Unlike my BJ70 which was in rough shape to start with, this BJ74 is in substantially better condition and I'd like to keep it that way as long as possible. It's not as "nice" as some of the trucks you see posted but I'm quite happy with it. Anyways, on to some questions (don't laugh ). - What coolant type does the 13BT require? It's red but is there a specific name and is it usually a 50/50 mix? - I've heard mention of a 3M spray for the frame that some use to coat it for some extra protection. Is there a name for it or part number perhaps? - What brand of grease do you guys recommend for the chassis, driveshafts, various balljoints and knuckles? Can you use the same type for all the various lube points? - Does anyone have a quick tutorial for operating the winch? The instructions are in Japanese and mine's..uhh...well... - The truck has an altimeter as well as an outside/inside temp display. The altimeter works but the temp is intermitent. Where are the sensors for the temp located? - My BJ70 has all the 4WD controls on the secondary stick, while the BJ74 has a 4H button. To operate it I just lock the hubs and hit the switch? When I want to go into 4L, turn the 4H button off and pull the lever into position? That's all I can think of for now but I'm sure I'll think of more.
