How do you replace the cooling tubes under the intake manifold in a 1994 plymouth voyager with a 3.0 V6

If its a 4 cyl. it is pass side front of engine on side down low. have to get at from bottom. If its v6 it is on the iside of timing belt assembly and runs of of that system must pull covers off to get to.

under the hood there should be another fuse box with the relays in them..

Is this the rear bank that you are having trouble with.....I do not know about the 3.0l but the 3.3l is greatly eased by removing the upper intake manifold. Disconnect the throttle body and rear alternator mount bolt then remove the bolts holding the upper intake to the lower intake. Now all 3 rear plugs are in easy reach. Reassemble in reverse remembering to torque appropriately.

get a mirror and a light, works for me

For 1994 Plymouth Truck Voyager 2WD 3.0L MFI 6cyl the MAP Sensor is located under hood, passenger side, upper engine area, end of intake manifold cover, mounted next to alternator on engine.

Hope helps (remember rated this).

API SG or SG/CD look on the Cap or Label of the Oil Container (Quart, Gallon, or 5 Quarts).
10W 30 for Winter.
10W 40 for Summer.
V6 3.0L gets 4.0-quarts.
V6 3.3L and 3.8L gets 4.5 quarts.
Always change Oil Filter with the Oil Change.

So you dont know where it is, or what it looks like, but you know its bad, and need to replace it? Its on the end of the intake plenum, 3 wires, once you find it, you will figure out how to replace it.

I assume this is a 3.0L v6 and that the metal tube that goes under the intake is leaking.This tube can be removed without taking the intake off. There are two bolts holding the tube under the intake on at the transmission side to the tube.The other end of the tube has an "o" ring on it that seals to the back of the water pump housing.Take the radiator hose off of the tube and then the two bolts need to be removed. Now try to pry against the bracket the the bolts were in and move the tube away from the engine. Pull the tube all the way out of the area from beneath the intake and either replace the tube if necessary or just replace the seal. Install by reversing removal procedure. Lubricate seal with silicone greas so seal will slide rather than get damaged upon installation.

Hope this helps

I don't believe your particular vehicle's cooling system needs to be bled during coolant filling, but check the coolant level first. It seems that the coolant level is too low for the sensors to be able to sense the temperature, or the sensors are disconnected. Look for a connector on the intake manifold, near the coolant outlet. Ensure it is properly connected.
