=== Engine Bay Modifications ===

* Replace the heater hose connector at the back of the engine (above #6 spark plug). Tip: Remove the fuel injector blower (right side, spark plug side) for easier access. Removing spark plug wires (after numbering) and intake manifold vacuum lines may also help.
* Replace the auto control single-hose fitting with the manual control two-hose fitting.
* Remove the old fitting and install the new one using Teflon tape on the threads.
Orient the fitting as shown in
'''Figure 6-1'''. - Replace the water temperature switch (auto system) with the valve-pressure regulator tee.
* Replace remaining heater hoses and connect as shown in Figures 6-1 and 6-2.
* Route new heater hoses through the firewall and connect per Figure 6-1.

Note:

From the passenger seat view — the '''right-hand heater hose''' goes to the
two-hose fitting above the #6 spark plug, and the '''left-hand heater hose''' goes
to the valve-pressure regulator tee.

* Leave the fuel injector coolant blower out until the engine has been restarted and checked for leaks.
