sort of, but not necessarily. I installed a late model radiator on my old 88, but kept everything closed. as long as the cap has a higher rated pressure than the system uses normally, it's a closed system.
I've winched with one too. it was... eventually effective. lord knows we were screwed if it didn't eventually get the bronco out of that ice puddle. but both of us have winches now, so we learned both that the hi-lift can do the job, but also no one wants to actual use that thing for that purpose unless absolutely forced to.
where do you put the jack to lift up your vehicle? that's key. the biggest danger is the utter lack of friction holding the jack base or hoist point still. jacks slipping out of place is a very dangerous thing. plus as you lift the vehicle can shift causing the jack body to contact the Jeep body in ways you may not be happy about. plus occasionally the handle will snap back and try to kill you mid lift, but that might be more of an off-brand farm jack thing.
I carried a hi-lift everywhere I went, but I never used it because I also carried a hydraulic floor jack. all my experience with hi-lifts comes from other people using them.
media means books of some kind. I didn't see posters anywhere in the explanation.
I tried shrinking the size, but the price was the same. I'm getting the feeling that (like first class mail) I can't do the cheaper options from home. I gotta go in person.
do you guys down under have any ideas for affordably shipping a 20x6x6 practically empty cardboard box (just a poster inside) to Australia? the USPS wants 75 bucks! that's the online express price though, I haven't yet gone to the post office to see if a cheaper option exists.
I know own them all now (barring the last book ethat's currently being written). this was harder than I thought since they are all out of print and some issues have gone way up in value. lots of hunting and waiting for ones that are listed for cheaper.
