Head gasket water holes are completely close up the front, and gradually open more as water gets to the rear cylinders. We know that water flow takes the path of least resistance, and that the water pump is at the very front of the engine. The idea is to make cool water flow through the front cylinders and continue flowing all the way to the back of the block. Did you ever inspect the water holes in a head gasket? They are a lot smaller than the holes in the block or the head.
DaveĮngine Engineers really go through some hoops trying to get the engine to cool evenly. If not, it's time to troubleshoot before temps soar. Added 50/50 with a good name brand antifreeze, your system should work well.
Without cooling system improvements (like an electric fan and a good alternator), they cannot do long parades.ĭistilled water is good if your water is too hard. These cars were not made to sit with the engine running at 'idle' for long periods of time or they will certainly overheat. It could be that the pump vanes have eroded and become inefficient at low speeds, or something is restricting flow in the block.īefore adding a six-blade fan and full shroud, I would forward and back flush the block a few times and see what comes out. If your temp gauge shows 'normal' at highway speeds and elevates at speeds around town, that's a classic example of restricted flow your water pump isn't pushing enough to flow coolant and/or air isn't going around the cores. Corrosion can be so bad that your block core plugs will eventually rust through. Over time and especially if you don't keep up with regular antifreeze flushes, crud settles to the bottom of your block, head gaskets start to open holes around the front cylinder passages, radiators tend to close and so do heater cores. Of course, everything was new, but your car could operate in the Mojave with no problem and with a stock fan and no shroud.Ĭoolant needs to flow through your engine and radiator and air needs to flow around your radiator cores.
Charles, when your car left the factory Ford installed City water and antifreeze.
