Removing the fuel heater element
Firstly, it's important to understand the options available for bypassing the fuel heater. One common approach is to unscrew the fuel heater, remove the heating element, and then screw the bowl back on. The bowl typically has a screen that can filter the fuel before it reaches the lift pump. Alternatively, you can choose to install an inline filter before the lift pump and completely remove the fuel heater assembly. This option often requires a spacer to ensure the lift pump is correctly positioned, as the heater assembly is usually mounted between the lift pump and the block.
Before beginning any work, ensure you have the necessary tools and safety equipment, such as gloves and eye protection. Once you're ready to start, locate the fuel heater and carefully follow the fuel lines to identify the correct unit. Then, using the appropriate tools, proceed to unscrew and remove the fuel heater, including the heating element. Clean the area and inspect for any signs of damage or wear.
If you choose to install an inline filter, now is the time to do so. Ensure that any new components are compatible with your vehicle and follow the manufacturer's instructions for installation. Secure all connections and ensure there are no leaks. If you're not installing an inline filter, simply screw the bowl back on, ensuring the screen is in place to filter the fuel.
Finally, once the fuel heater element has been removed and any necessary replacements or additions have been made, carefully reassemble all the components, ensuring everything is securely connected. Check the fuel system for leaks and ensure that all parts are properly secured before starting the engine.

Sealing off the thermostat/wiring harness
First, it is important to locate the thermostat housing. This can be done by following the upper radiator to the engine. Once the thermostat housing is located, it is necessary to remove it from the engine. If the housing is stuck, a soft-faced hammer can be used to gently tap it and loosen it. Be prepared for some coolant to spill during this process as the gasket seal will be broken.
Next, pay attention to the orientation of the thermostat, noting which end is facing up or out, and the position of the air bleed "jiggle valve" if your engine is equipped with one. Remove the thermostat from the engine. On 3.9L V6, 5.2L V8, and 5.9L V8 engines, it is recommended to stuff a rag into the engine thermostat opening to prevent any debris or foreign objects from entering the engine during this process.
After the thermostat has been removed, clean the gasket mating surfaces with a gasket scraper to remove any traces of old gasket material and sealant. Ensure that the surfaces are thoroughly cleaned with a chemical gasket remover, lacquer thinner, or acetone.
Now, you can seal off the wiring harness and thermostat area. This can be done by applying a thin, uniform layer of RTV sealant to both sides of a new gasket. Position the new gasket over the area where the thermostat was located, ensuring that it is properly aligned and inserted into the thermostat housing.
Finally, reinstall any components that were removed during the process, such as the alternator and alternator bracket. Reconnect the negative battery terminal(s) and refill the cooling system with coolant if it was drained.
By following these steps, you can effectively seal off the thermostat and wiring harness when removing the fuel heater pre-filter in your 1997 Dodge.
