This is easier than it may look.
Look at all the rollers/ulleys that the belt must pass over/around/through. The ones that are smooth are the ones that get the back end of the belt and are used to change the direction of the belt. The ones with grooves are the ones that are actually driven by the belt.
One of the rollers near the top and towards the firewall is actually spring loaded. I believe it is the one that is 2nd nearest to the firewall. Put a wrench on it and pull. You will see it rocks downward allowing you to jump the belt onto it.
So, the way to get it is to thread the belt over all of the rollers except this one (the grooves on the belt face would in when you thread it if it were a pure circle), making sure you are driving the proper pulleys (as described in the first paragraph). With the belt threaded over all but the pulley you can pivot, pull with a wrench on this tensioning pulley and work the belt onto it... It self tensions so at that point you are done.
Start @ front of vehicle w/ AC pulley work your way down and backward until you have reached the alternator pulley. [Note] this means laying the belt on the tensioner.. The alternator pulley will be the last to put on; as you can not put the belt on the tensioner with a wrench on it. Once the belt is routed in the manner described in both answers (except the laying belt on tensioner in this answer) put 15 metric long handle boxed wrench on tensioner and pull towards you. Slip the belt over alternator pulley. THEN your done.
I forgot to add that the motor in this 94 Dodge Grand Caravan ES is a 3.3L
No.
fuel tank capacity on 1994 Grand caravan is 77 litres.

Serpentine brote change
The 1994 Dodge Caravan/Grand Caravan takes a 22" driver side, 18" passenger side and 18" rear replacement windshield wiper blades.
you need a inner tie rod tool
No, completely different bell housing patterns.
My 1994 holds 20 gallons:)
The question is to vague. The aver age price of say a 1994 Dodge Grand Caravan will Drastically change from that of a 2009 Dodge Grand Caravan. For a new minivan the average price tag is about $24,000 nicely loaded.
it is easiest to remove the serpentine belt first (draw a map so you can put this belt back on) then pull the right front tire and inner splash guard to gain the easiest access. assuming this is a 3.0 L engine
nope have to take off the tank
