The procedure is similar for both Ford and Mercury car models:----

The details to replace Crankshaft Front Seal is as follows:---

Removal & Installation

2.3L Engine

Specific to:

Ford Escape 2008

Mercury Mariner 2008

WARNING

Do not loosen or remove the crankshaft pulley bolt without first installing the special tools as instructed in this procedure. The crankshaft pulley and the crankshaft timing sprocket are not keyed to the crankshaft. The crankshaft, the crankshaft sprocket and the pulley are fitted together by friction, using diamond washers between the flange faces on each part. For that reason, the crankshaft sprocket is also unfastened if you loosen the pulley bolt. Before any repair requiring loosening or removal of the crankshaft pulley bolt, the crankshaft and camshafts must be locked in place by the special service tools, otherwise severe engine damage can occur.

WARNING

During engine repair procedures, cleanliness is extremely important. Any foreign material (including any material created while cleaning gasket surfaces) that enters the oil passages, coolant passages or the oil pan can cause engine failure.

Fig. Special tools required

1. Before servicing the vehicle, refer to the Precautions Section.
2. Remove the crankshaft pulley. Refer to Crankshaft Damper Removal & Installation in this section.
3. Using the special tool, remove the crankshaft front oil seal. Use care not to damage the engine front cover or the crankshaft when removing the seal.

2.3L Engines

Specific to:

Ford Escape 2006-2008

Mercury Mariner 2006-2008

1. Before servicing the vehicle, refer to the Precautions Section.
   
   WARNING

   During engine repair procedures, cleanliness is extremely important. Any foreign material, including any material created while cleaning gasket surfaces that enters the oil passages, coolant passages or the oil pan can cause engine failure.  
   
   
   
   WARNING

   The crankshaft, the crankshaft sprocket and the pulley are fitted together by friction, using diamond washers between the flange faces on each part. For that reason, the crankshaft sprocket is also unfastened if you loosen the pulley. Therefore, the engine must be retimed each time the damper is removed. Otherwise severe engine damage can occur.
2. With the vehicle in NEUTRAL, position it on a hoist.

3. Remove the accessory drive belt.
4. Remove the valve cover.
   
   WARNING

   Failure to position the No. 1 piston at top dead center (TDC) can result in damage to the engine. Turn the engine in the normal direction of rotation only.
5. Using the crankshaft pulley bolt, turn the crankshaft clockwise to position the No. 1 piston at top dead center (TDC).
   
   WARNING

   The special tool 303-465 is for camshaft alignment only. Using this tool to prevent engine rotation can result in engine damage.
   
   
   
   NOTE

   The camshaft timing slots are offset. If the special tool cannot be installed, rotate the crankshaft one complete revolution clockwise to correctly position the camshafts.

6. Install the special tool in the slots on the rear of both camshafts.
   
   NOTE

   Installing the special tool in this step will prevent the engine from being rotated in the clockwise direction.
7. Install special tool 303-507.
8. Remove the crankshaft pulley bolt and washer.

   NOTE

   Do not reuse the crankshaft damper bolt.
   
   
   
   NOTE

   Apply clean engine oil on the seal area before installing.
2. Install the crankshaft pulley and hand-tighten the bolt.
   
   WARNING

   Only hand-tighten the bolt or damage to the front cover can occur.
   
   
   
   NOTE

   This step will correctly align the crankshaft pulley to the crankshaft.
3. Install a standard 6 mm x 18 mm bolt through the crankshaft pulley and thread it into the front cover. Rotate the pulley as necessary to align the bolt holes.
   
   WARNING

   Failure to hold the crankshaft pulley in place while tightening the bolt can cause damage to the engine front cover.
4. Using the special tools to hold the crankshaft pulley in place, tighten the crankshaft pulley bolt in two stages:
   1. Stage 1: Tighten to 74 ft. lbs. (100 Nm).
   2. Stage 2: Tighten an additional 90 degrees ( ¹ / ₄ turn).
5. Remove the 6 mm x 18 mm bolt.
6. Remove the special tools.
   
   NOTE

   Only turn the engine in the normal direction of rotation.
7. Turn the engine two complete revolutions.

9. Install special tool 303-507.
   
   WARNING

   Only hand-tighten the bolt or damage to the front cover can occur.
10. Using the 6 mm x 18 mm bolt, check the position of the crankshaft pulley. If it is not possible to install the bolt, correct the engine timing.
11. Using special tool 303-465, check the position of the camshafts. If it is not possible to install the special tool, correct the engine timing.
