I have used this for advice regarding repairs and maintenance,
this is my first effort trying to give back.
The vehicle specifically involved was a 1989 XJ6 base, 3.6L
left hand drive.
10 mm socket
13 mm socket
less than 8 inch long ratchet
less than 6 inch long ratchet
screwdriver and/or hose clamp sockets/driver
2 medium-size allen key
hammer with wooden handle or rubber grip
nylon/scotch abrasive pad
acetone and rubbing alcohol
lighting and a step
plastic bag large enough to fit water rail
2 EAC9745 gaskets
small bungee cord
To begin, I discovered that these gaskets frequently fail when
the water rail hose is replaced. The gaskets are more a means
of applying sealant to the mating areas then they are a classic
gasket. If the water rail securing bolts work their way loose
the gaskets will fail if you try to install a new hose. Do
yourself a favor and check and tighten these bolts before
attempting to replacing the hose.
- Displace and secure the battery ground lead.
- Remove the air box. Two securing nuts are visible.
The third is in the front, down low and difficult to see. I
removed the top half of the box first for ease of access.
- Unplug and remove the air meter. Be sure to disconnect
the ground wire located on the front corner closest to the fan.
- Remove the bolt securing the oil filler pipe to the
inlet manifold and displace the attached vacuum hose. Displace
and secure the filler pipe to the inlet manifold using a small
- Jack up vehicle. To maximize drainage and to avoid
getting wet, raise only the left front.
- Drain radiator.
- Displace the expansion tank hose at the water pump and
move out of the way.
- Remove vacuum hoses from thermostat as needed for
access to the water rail through the front of the inlet
manifold. Label vacuum hoses as needed.
- Remove bypass hose from the thermostat to the water
- Displace heater hose from water pump and from the
resistor located at the top center of the inlet manifold. Move
hose out of the way to open access to the water rail.
- Remove hose from thermostat to resistor, noted above.
- Displace the vacuum hose from the cam cover pulling it
down through the inlet manifold and out of the way.
- Unplug the wire from the device attached to the block
below the water rail. It pulls off simply.
- From under the car displace the starter ground cable at
the solenoid using the 13 mm socket and the small ratchet.
The teardown to access the water rail is now complete.
- Remove the water rail hose.–
