Rolling the Montana Engine Forward

[463]

i use a battery charger on the hot post under the hood and a good ground. the 12dc charger at 2 amps would not have enough juice to allow the van to start. but it keeps the codes in the radio and the computer. disclaimer: use at your own risk.

I haven't done this in a few years , so I don't know if it will work on these vans. A long time ago a salesman gave us a trick in the garage to keep the radio station pre-sets from deleting when disconnecting the battery. He simply took a plug that goes in the cigarette lighter,( the kind you find on many accessories that plug into that port, the part can usually be purchased separately from an auto parts store.)He took the two wires that come off that plug and attached a 9 volt battery end,( the kind that attaches onto a 9 volt battery that has the 2 nodes .) You then attach a 9 volt battery to the end of the plug and put the plug in your cigarette lighter ,( or accessory plug,) and can now disconnect the battery without losing your pre-sets.

That's how I did it. It's slow, but you don't have to worry about crushing your cooling fans or damaging your radiator.

you can only roll it forward so much and then you have to end up dropping the front of the subframe and you can only drop it three inches and contened with it trying to grab part of the fascia as it drops. but the way up by the exhaust is the fast way if you take into account the time it takes to roll the motor forward and drop the subframe just to get at the backside of the motor.
