  Q: How to Replace and Maintain a Camshaft Seal on the Left Cylinder Head on Chrysler Pacifica?

  A:

  Before starting any work on the left cylinder head oil seal, take off the negative Battery Cable and drain the cooling system. Mark the front gear with the front gear, while aligning the marks of both Camshaft gear and crankshaft gear to TDC. Next, remove the front Timing Cover and then tighten the ten nuts on the back covers, installing the cylinder head cover and fix the Rocker Arm assembly. Remove the camshaft thrust plate from the cylinder head and coax the camshaft to slide backward to a point about 3.5 inches outside the head without touching or scratching any of the important areas. Choose an appropriate removal tool and slowly take out the oil seal from the camshaft. Before use, put the new seal into the cylinder head and hit it with the special tool MD-998306 to lock it into position. Take a little engine oil and rub it on the edge of the oil seal and on the Special Tool Seal Protector sleeve and fit the sleeve onto the camshaft. Place the camshaft against the camshaft tube, insert the seal protector through the camshaft seal and as the camshaft seats, remove Special Tool 6788. Place the timing marks on the camshaft and belt, then reinstall the thrust plate, basic gear, rear timing cover and belt. Then, install the rocker arm assembly, cylinder head cover, front Timing Belt cover and vibration damper according to the instructions. After that, establish the coolant level and restore contact between the negative battery terminal and the body shop metal.

  Q: How to Service and Repair a Camshaft Seal on Chrysler Pacifica?

  A:

  You should begin by removing the negative Battery Cable to work on the Camshaft oil seal. For a properly sized cylinder head, remove the front Timing Cover, align the camshaft gear and crankshaft gear timing marks to TDC, then eliminate the Timing Belt and the right camshaft sprocket. Next, remove the camshaft thrust plate from the rear of the cylinder head, after that remove the cylinder head cover and Rocker Arm assembly. Position the camshaft so that its rearmost end is out of the head by about 3.5 inches, without scratching the cylinder head's seal or camshaft journal surfaces. Take off the camshaft oil seal by using a suitable driver. To remove the left cylinder head, cut off the negative battery connection, drain the cooling system, repeat the steps for the front timing cover, align timing marks, take off the rear timing cover, cover of the cylinder head, rocker arms and thrust plate for the camshaft. As before, slide the camshaft backward and out of the cylinder head around 3.5 inches and take out the camshaft oil seal without making any damage. To set the camshaft seal onto the cylinder head correctly, place it in place and then use the tool MD-998306 to tap it in. Brush some clean engine oil on the camshaft oil seal lip and Special Tool 6788 Seal Protector Sleeve before installing the sleeve on the camshaft. Forward the camshaft and insert the seal protector around the shaft, pushing it up until the camshaft is seated. Then, take away the assembly sleeve. In the next step, install the camshaft thrust plate, camshaft sprocket and the timing belt. On the left cylinder head, slip the camshaft seal over the camshaft and tap it firmly into position with MD-998306, smear some engine oil on the seal lip and sleeve and push the camshaft into place as before. Following this, place the rear timing belt cover, the camshaft gear and match the timing marks and install the timing belt, rocker arm assembly, cylinder head cover, front timing belt cover and vibration damper. After that, fill the coolant and attach the negative battery cable again.
