So Fix it

Remove the cap for the fuel filler tube to relieve the pressure in the fuel tank. Remove the cap on the fuel pressure port located on the fuel rail. Place one end of hose C-3799-1 into a gasoline container and connect the other end to the fuel pressure port to relieve the pressure in the fuel system. Remove the hose from the fuel pressure port and replace the cap for the fuel pressure port. Drain the fuel tank.

Disconnect the cable to the negative terminal on the battery with a socket wrench. Support the fuel tank and loosen the bolts for the fuel tank strap. Disconnect the fuel lines from the fuel tank and unplug the wiring harness for the fuel pump module.

Lower the fuel tank and turn the locking ring counter-clockwise with a wrench. Remove the locking ring and disconnect the fuel pump from the fuel tank.

Connect the new fuel pump module to the fuel tank, and replace the locking ring. Tighten the locking ring to 40 foot-lbs. with a torque wrench. Raise the fuel tank back into position. Connect the wiring harness and fuel lines for the fuel pump module. Tighten the bolts on the fuel tank strap to 250 inches-lbs. with a torque wrench.

Connect the cable to the negative terminal of the battery with a socket wrench, and fill the fuel tank with fuel. Start the engine and check the fuel system for leaks.

Remove the radiator cap from the radiator. The cap is on the left side, on the top of the radiator. This releases pressure in the coolant system. Do not remove the cap while the engine is hot.

Remove the band clamp that secures the lower radiator hose to the radiator outlet. Use a screwdriver to remove the clamp. Pull the hose off the radiator and drain the fluid into a drainage pan. Slide the hose back onto the radiator outlet and secure it in place with the band clamp.

Follow the upper radiator hose to the point where the hose connects to the top of the engine. Remove the band clamp from the hose with the screwdriver and pull the hose off the thermostat housing. Push the hose off to the side to gain access to the housing.

Remove the two bolts that secure the thermostat housing to the manifold of the Dodge Caravan with a 9/16-inch socket and ratchet. Lift the housing off the Caravan to expose the thermostat.

Pull the old thermostat out of the intake and discard it.

Shove a rag into the hole the thermostat sat in to prevent old gasket material from falling into the cooling system.

Scrape the old thermostat gasket off the intake manifold and the bottom of the thermostat housing and wipe everything down with a rag.

Remove the rag and place the new thermostat into the Caravans intake. The end with the spring on it sits inside of the intake.

Place a bead of RTV silicone around the base of the thermostat housing and place the housing back onto the intake. Secure it with the bolts.

Reconnect the upper radiator hose and secure it with the band clamp.

Drain the radiator fluid back into the radiator, using the filler cap. Replace the radiator cap once finished.

Locate the negative battery cable on the top of the battery. Loosen the clamp bolt with a wrench, then remove the cable from the battery.

Loosen the clamp bolt on the positive battery cable with a wrench and remove it as well. Isolate the battery cables so that they are out of the way and cannot fall back against the battery.

Locate the retaining clamp and bolt near the bottom of the battery on the inboard side of the tray. Remove the nut from the retaining clamp with a socket, extension bar and ratchet. Remove the retaining clamp and lift the battery out of the van.

Locate the three retaining bolts that hold the battery tray into the van. There are two in the base of the tray and a third just to the front of the retaining clamp location. Remove the two in the tray with a socket and ratchet then set them aside.

Remove the third retaining bolt with a wrench, set the bolt aside, and lift the tray out of the engine compartment.
