Were can i find a diagram of water pump replacement for a 1987 plymouth voyager mini van with a 3 liter v 6. Not sure how to replace it.

if you follow the pipe does it go towards the transmission ? if so it's for the trans cooler. If not it will be the escape hose incase of overheating/to much pressure in the coolant system , if you go to a parts retailer like autozone they will have the part named on their data system , its a bit difficult without seeing vehicle to name parts . although you have given a good description, the lower rad hose carries cooled coolant so i would think it's the trans cooler but check at autozone or similar

Hope this helps (remember rated and comment this).

Have you replaced the plug wires? If they have too much resistance they can cause the coil to fail.

you can do some searching on web and library but chances are slim u find a diagram for that so u have 2 options

1. play with it and eventually figure it out (very time consuming and hair pulling involed)

2 . go to a junk yard and see how it is on a van or car

it should take an experienced mechanic about two hours a do it yourselfer will take longer depending upon their mechanical abilities

80 percent of the time the transmission problem is electrical. Pull the transmission dip stick and check the condition of the transmission fluid. If it's not burn and the transmission runs with out slipping but does not shift properly. Good chances are that it may be the Transmission control module (TCM) which is on the passenger side fender close to the headlight. Check the condition of the wire harness to the TCM, look for corrosion and try disconnection the TCM and see if there is any changes to the way the transmission performs. As for the transmission fitting, as long as the engine size are the same. the 3 liter and 3.3 liter use different transmission. Good luck and hope this helps.

well it can only come from the radiator hoses or the water pump...

to check if your water pump is still good just take a flashlight and spot on top of the pump. there should be a little hole on top behind the pulley. if it is damp you have to replace the pump.

besides that just check the hoses one at the time

sounds like the heater core is leaking inside the dash.
