The van {2000 grand caravan with 3.3 liter engine} is in motion in a variety of modes, highway,city driving. 55 to 30mph straight and turning corners. the car is pulled to the side or at stop light and restarts immediately. no sputtering or anything resembling a fuel problem. just shuts down like the car was turned off.

Removing and changing the water pump on a 2000 Grand Caravan should only be done if your van has a 3.3 liter or 3.8 liter V6 engine. On any other engine types, including four-cylinder engines, you must remove the timing belt from the engine to access the water pump, which is a dangerous task that can mess up the engine if attempted by an amateur.
The procedure is as follows:------------- The water pump is responsible for sending the engine coolant to the engine.First of all remove the serpentine belt then remove the plastic cove on the passenger side behind the wheel. You will have to remove the pulley. Once the pulley is removed unbolt the water pump and remove it. Clean the surfaces and install new pump. Draining the coolant and replacing it is advisable.Drain the engine coolant, twisting and removing the drain plug at the bottom of the radiator
-------------------Thats it.

the starter is located on the front of the engine if you stand in frt of the van the starter is to the right by the oil pan,slide under the front of the van and you will see it where the engine and trany come together. hope this helps.

U have to get at it from under the van.

The o2 sensors are located on the exhaust system.The upstream in on the rear exhaust manifold and the down stream is in front of the catalytic converter.Usually when they are bad they will make the check engine like go on.Make sure the air filter is clean,tires at correct inflation,alignment is to specs.If the vehicles pulls to one side or the other or steering wheel is not straight when driving down a straight stretch of road.Also tires are wearing normal.Use cruise control where ever on highway.If you let your vehicle warm up in winter.This also uses gas.Hope this helps.Good luck.

code po700 is to tell the ecm and you there is a trans.problem and dtc set in trans.module. po755 is a trans. shift solenoid problem. check trans.fluid level when hot and color of fluid ,dark is not good,burnt smell not good .chrysler has a large trans.problem need to visit a trans. shop for repairs.hope this helps.

First I need to ask is it a 4 speed or a 3 speed transmission. If it's a 4 speed when driving down the road pull it from drive to third gear. You shpuld hear the engine speed up if it does not then that means you have on 4th gear and you will have to take it to a transmission shop. If it's a 3 speed then just count the shift points if all 3 gears are present then drive down the road and see if the van goes into tcc. When you mean the rpms are high how high are they.

Im assuming it is an engine that uses a timing belt. It sounds like the belt has jumped 1 tooth. if it only jumped 1 tooth than the computer will compesate the timing so it is possible the sensors will say they are ok. If it is a motor that uses a chain than it problaly needs a new gear/chain set.
