Contour Enthusiasts Group Archives Forums General Troubleshooting Zetec Motor Mount

I had a motor mount go out on me, I, of course, thought it was the cheap one on the transmission that connects to the front of the car. but after getting it up in the air and checking it closely, found out it was not. It turns out to be the hydraulic motor mount on the right side if the car at the front of the engine. It's so bad that while holding the brakes, with the car running i can put it into gear and rev the pedal and watch the right side of the engine jump up and then slam down onto the subframe.

Has anyone changed out this $70 mount before? and if so what kind of troubles might I be in for.

mine is busted and it squeaks constantly, i cant figure it out, so after i move in june i will have it fixed.

Below verbatim from '98 cd, Engine Support Insulators - Alignment Procedures.

1. Note: Alignment of the engine/transaxle assembly is necessary in the case of any repairs to the subframe and support insulators, or if the engine starts to make booming noises.
Note: The locations of support insulators and engine support insulators are described looking from the transaxle to the engine.
Note: Steps which apply only to particular variants are indicated with a note.
2. Disconnect the battery ground cable.
3. Remove the battery.
4. Remove the air cleaner (ACL).
- 1 Disconnect the crankcase ventilation hose.
- 2 Disconnect two clips.
- 3 Disconnect the intake hose.
5. Install the special tools.
6. Disconnect the coolant expansion tank and lay it to one side.
- l Disconnect the speed control cable (if equipped) from the coolant expansion tank.
7. Loosen the bolts on the front support insulator two turns.
8. Loosen the bolts on the rear support insulator two turns.
9. Raise and support the vehicle. For additional information, refer to «Section 100-02».
10. Remove the engine undershield (if equipped).
- l Remove nine bolts.
11. Loosen the bolts of the right - hand engine support insulator two turns.
- 1 Remove the center bolt.
- 2 Remove the bracket bolts.
12. Note: The engine support insulator cannot be taken out at this stage.
Remove the left - hand engine support insulator.
13. Remove the left - hand engine support insulator.
- l Remove the bracket of the left - hand engine support insulator.
- 2 Remove the engine support insulator.
- 3 Install the bracket again.
14. Note: It should be possible to insert the locating pins free of strain in the subframe and body locating bores.
Using the special tools, check the position of the subframe.
15. Note: The subframe must not move during the tightening operation.
Align the subframe (as necessary).
- 1 With the special tool inserted, tighten the four bolts, working diagonally.
- 2 Remove the special tools.
16. Lower the vehicle.
17. Install the special tool in the place of the left - hand engine support insulator.
18. CAUTION: Do not distort or turn the support insulator.
Align the rear support insulator bracket and secure it.
19. CAUTION: Do not distort or turn the support insulator.
Align the front support insulator bracket and secure it.
20. Remove the special tools.
21. Raise and support the vehicle. For additional information, refer to «Section 100-02».
22. Tighten the bolts of the right - hand engine support insulator.
- 1 Bracket bolts
- 2 Center bolt.
23. Remove the special tool.
- 1 Remove the bolt.
- 2 Remove the special tool from the subframe.
24. Install the left - hand engine support insulator.
- l Remove the bracket of the left - hand engine support insulator from the transaxle.
- 2 Install the engine support insulator.
- 3 Install the bracket again.
25. CAUTION: Do not tilt the engine support insulator.
Install the left - hand engine support insulator.
- 1 Attach the engine support insulator to the subframe (two bolts).
- 2 Install the center bolt.
26. Install the engine undershield (if equipped).
27. Lower the vehicle.
28. Install the coolant expansion tank.
- l Attach the speed control cable (if equipped) to the coolant expansion tank.
29. Install the air cleaner (ACL).
- l Press the ACL into the rubber bushes.
- 2 Connect the crankcase ventilation hose.
- 3Install the two clips.
- 4Connect the intake hose.
30. Install the battery.
31. Note: When the battery has been disconnected and reconnected, some abnormal drive symptoms my occur while the vehicle relearns its adaptive strategy. The vehicle may need to be driven 16 km (10 miles) or more tor relearn the strategy.
Connect the battery ground cable.
32. Check the fluid levels and correct as necessary.
33. Check the routing of the vacuum hoses and wiring and secure them with Cable ties

Might help. Wasn't able to find any item solely on re & re of front mount.


Edited to single space.

ok so what does it say about the "special tool" is that like a specil ed student with a screwdriver?

Special tools are various engine support devices and alignment jigs, unable to post pics of same. However, this is complete procedure for the re-installation of complete powertrain. You should be able to short circuit many of the steps, including alignment, if only doing one mount.

Hopefully someone who has done the front mount on the I4 will post, but you could try a search for 'motor mount' in the interim and see what turns up.

Sometimes these tasks exceed our DIY experience/abilities or require more than driveway tools and it's best to take to shop. Up to you to judge.

May have scared you off with above.

Here's a post I dug up from member bentleywarren:

I've replaced the front and rear roll restrictors, and I removed, checked, and re-installed the mount on the driver's side. It's a straightforward job. I used a bottle jack, with a block of wood on top, to slightly lift the engine/trans. I only lifted it an inch or so, just to take the pressure off of the mounts. My only advice is to make sure when you reinstall the mounts that they aren't binding. When re-installing, the bolts go through slots, rather than round holes, so the mounts can be shifted as needed. If the mount is mis-aligned, you can get stress and vibration.

Makes it sound like a piece of cake.
