Flathead V8 Water Pump & Mount Service Guide1937–1948 Ford Passenger Car | 1939–1948 Mercury V8 Servicing the cooling system on a 1937–1948 Ford passenger car or 1939–1948 Mercury V8 requires more than just swapping a part. The flathead platform integrates the water pumps, front engine mounts, and cooling hoses in a way that makes access and sequencing important. Whether you’re replacing water pumps, water pump bolts, or addressing motor mounts at the same time, the process benefits from a clear plan. The parts referenced here include: 78-8501-PR – Water Pumps 78-8501-HK – Water Pump Bolts 78-6038-BDK – Motor Mounts These components are commonly serviced together on 37–48 Ford and 39–48 Mercury V8 applications due to their physical proximity and shared mounting areas. Why These Systems Overlap On these flathead V8 engines, the water pumps mount at the front of the block and are positioned near the front motor mount assembly. In many cases, removing the pumps requires relieving load from the mounts. Aging rubber mounts can sag over time, changing engine position slightly and complicating pump removal or installation. Addressing motor mounts during cooling system service can help maintain proper engine alignment. Fitment may vary slightly by model year or chassis configuration. Always confirm application for Ford passenger car versus Mercury V8 before ordering parts. Give us a call or email and we will answer your questions! Basic Removal Sequence A structured approach reduces stress on hardware and surrounding components: Drain CoolantBegin by fully draining the cooling system. Open the radiator petcock and, if equipped, block drains to remove as much coolant as possible. Remove Radiator Hoses (Upper and Lower)Disconnect both hoses from the radiator and water pump outlets. Inspect hose condition during removal. Loosen Motor Mount BoltsThe front motor mount assembly may need to be loosened to allow slight engine movement. Do not fully remove the mount until the engine is properly supported. Support the EngineCarefully jack up the engine using a wood block under the oil pan. The wood block helps distribute load. Raise only enough to relieve tension from the mounts. Remove All Eight Water Pump BoltsEach pump is secured with multiple bolts. Remove all mounting hardware evenly to prevent binding. The water pump bolt kit (78-8501-HK) ensures proper hardware replacement if originals are corroded or worn. *PRO TIP there is a bolt in each of the lower water pump outlets. Once the bolts are removed, the water pumps (78-8501-PR) can be removed from the block. Surfaces should be cleaned thoroughly before re-installation. Motor Mount Considerations The motor mount kit (78-6038-BDK) supports the engine’s front weight and isolates vibration from the frame. When mounts are deteriorated, engine position may shift slightly. Replacing mounts during water pump service is practical because access is already established and the engine is supported. Fitment should always be verified for specific Ford passenger car or Mercury V8 applications within the 1937–1948 and 1939–1948 ranges. Restoration-Focused Approach Flathead cooling system service is straightforward when handled methodically. These engines were designed for serviceability, but age introduces corrosion, hardware fatigue, and rubber deterioration. Replacing water pumps, water pump bolts, and motor mounts as a coordinated service helps maintain structural alignment and cooling integrity. Taking the time to follow proper removal steps protects original components and ensures the flathead V8 continues operating as intended.

As a classic Ford enthusiast, my journey in the realm of restoration has been nothing short of exhausting. The thrill of bringing a vintage beauty back to its former glory is unparalleled. However, this passion comes with its challenges, the most significant being sourcing the right parts. This is where classic reproduction Ford parts have become a game-changer for someone like me. For years, the pursuit of authentic, original used and NOS parts was akin to searching for a needle in a haystack. These parts, often scarce and very expensive, could mean the difference between a stalled project and a triumphant restoration. Then entered the world of reproduction parts – a world that has not only made restoration more accessible but also more reliable. Initially, I was skeptical about using reproduction parts. Would they fit correctly? Would they maintain the authentic look and feel of my classic Ford? These concerns, however, were quickly dispelled. Modern reproduction parts are crafted so that they seamlessly blend with the original components. Manufacturers use advanced technologies and materials to replicate parts. One of the biggest advantages I've experienced with reproduction parts is the availability of parts. Unlike original parts, which may have undergone decades of wear and tear, reproduction parts are brand new and often incorporate modern engineering improvements. This doesn't just bring peace of mind; it enhances the driving experience, making it safer and more enjoyable. From a cost perspective, reproduction parts are generally more affordable than their NOS counterparts. This affordability has allowed me to allocate resources to other aspects of restoration, like professional paint jobs or interior refurbishments. Moreover, the availability of these parts means less time scouring swap meets and more time in the garage, doing what I love. In conclusion, classic reproduction Ford parts have transformed the restoration landscape for enthusiasts like me. They bridge the gap between the past and the present, ensuring that the legacy of classic Fords continues to cruise down our roads, not just reside in our memories. They are a testament to the evolving nature of car restoration, blending tradition with innovation, and keeping the spirit of classic Fords alive and roaring.

INSTALLING A CLASSIC FORD DISTRIBUTOR 1932-1941 Old Ford Trucks, 1932-1941 Ford Passenger Cars and 1939-1941 Mercury Cars with original V8 distributor: 1. Check inner caps one at a time to make sure they fit distributor housing, sand them if needed. Also check to make sure once installed rotor does not hit the inner cap. After fitting inner caps put inner and outer caps together with the spark plug wires and set aside. 2. Mount coil to distributor making sure coil brush makes contact with rotor and copper contact is not bent. 3. Make sure the mounting surface is clean and there is nothing in the camshaft slot where the distributor mounts. Check to make sure mounting bolt threads are clean and free of dirt, set bolts on top of engine for easy reach. 4. Time to mount the distributor. Put gasket on base of distributor, you can put a small amount of sealant on the gasket. Place distributor on to timing cover using fingers to turn rotor to make sure distributor is correctly seated in the camshaft. The distributor will mount flat to the timing cover when correctly installed. If the distributor is not seated correctly you can crack the distributor case when you tighten the bolts. Now you can put the three mounting bolts in and tighten. Do not over tighten(snug). 5. Install inner/outer caps to the distributor and pop the bail over to hold in place. 6. Install vacuum line to distributor. 1941-47 (6 Cylinder “G” Engine) Old Ford Trucks and Passenger Cars, 1942-1947 Old Ford Trucks and 1942-1948 Passenger Cars/Mercury Cars (V8): 1. Make sure the mounting surface is clean and there is nothing in the camshaft slot where the distributor mounts. Check to make sure mounting bolt threads are clean and free of dirt, set bolts on top of engine for easy reach. 2. Place the rotor on distributor and mount distributor cap and turn rotor slowly to make sure the rotor does not hit the inner cap. If rotor hits cap lightly file end of rotor till it clears. Remove distributor cap and set aside. Leave rotor on distributor. 3. Time to mount the distributor. Put gasket on base of distributor, you can put a small amount of sealant on the gasket, be sure not to get sealant on vacuum rubber grommet. Place distributor on to timing cover using fingers to turn rotor to make sure distributor is correctly seated in the camshaft. The distributor will mount flat to the timing cover when correctly installed. If the distributor is not seated correctly you can crack the distributor case when you tighten the bolts. Now you can put the two mounting bolts in and tighten. Do not over tighten(snug). 4. Install distributor cap and pop clips on for 42 crab cap. If you have a 46-48 with the inner and outer cap you will have to install plug wires into cap first before installing caps on distributor.
