Replacing your vehicle's timing belt can be a major project. With the proper tools and instruction, however, most self-proclaimed mechanics will be up to the task. Checking and replacing your Dodge Caravan's timing belt regularly ensures its optimum performance. Here's how that's done in Caravans with a 2.4L (VIN B) engine.
Instructions
Check Your Timing Belt
- 1
Check your owner's manual for the recommended mileage for replacing your timing belt. Replacement for Dodge Caravans is 60,000 miles.
2Locate the timing belt and examine it for breaks, damage, fraying, worn spots or looseness.
3Inspect the belt for cracked or missing teeth. It's possible that foreign material is collecting between them.
4Determine if the timing belt has damage on both sides. The timing belt's guide may cause single-side damage.
Remove Your Timing Belt
- 5
Disengage the negative battery cable and safely secure the car on jack stands.
6Detach the passenger inner splash-shield, the accessory drive belts and the crankshaft damper.
7Disconnect the right engine mount and mount bracket.
8Undo the retaining fasteners and lift the timing belt cover from the engine.
9Line up the timing belt sprockets, the timing belt and oil pump covers' timing marks.
10Unfasten the tensioner bolts on the timing belt and take out the belt and tensioner. The camshaft timing belt sprockets also may need to come out.
Install Your Timing Belt
- 11
Examine the cam and crankshaft sprockets. Replace if there is excessive wear or other damage. Secure the camshaft sprocket bolt at 85 foot pounds (101 Nm).
12Set the sprocket to "Top Dead Center" (TDC) by lining up the sprocket notch with the oil pump housing's arrow. Position the camshafts so the sprockets' timing marks align. Rotate the crankshaft one-half notch before TDC.
13Start installing the timing belt at the crankshaft. With the belt tight, bring it under the water pump sprocket. Route the belt along the idler pulley to the crankshaft sprockets and then to the tensioner pulley.
14Turn the crankshaft to TDC. Eliminate any slack by turning the sprocket to the right to TDC.
15Reattach the tensioner without securing it. Apply 250 inch pounds (28 Nm) of torque and tauten the tensioner's pulley bolt to 23 foot pounds (31 Nm).
16Take out the plunger pin. Recheck the timing marks by turning the crankshaft two rotations to the right.
17Reconnect the front timing belt cover and the engine mount and bracket. Secure the crankshaft damper at 105 foot pounds (142 Nm).
18Replace any remaining items that you disconnected. Lower the car and reconnect the negative battery cable. Start the engine and look for leaks.
