radiator inlet, radiator outlet and block temp. I am going to add not one but three temperature measuring probes. (once I reinstall the steering box which just got back from repair from other non-related issues). Perhaps pretty but not good for pumping at low speed.Īs my handle would suggest, the following plan of action is under way. The tolerances between the impeller and case as well as the backplate and impeller look a lot more precise. Looking at the aftermarket pump, it looks considerably better made than the stocker that I took off with the leaky seal. Ironically the problem was seperation of the water passage from the cooling little metal wrinkles of heat dissipating metal. I had a 76 LTD with a hopped up 400M and as the years wore on a noticed that it would heat up under heavy load on the highway. I am intrigued with mikes experience with clogged passages. RE: Water Pump Pulley Sizes for Early Ford Engines AllorNothing (Electrical) If the rad is hot and the engine hot there is probably not enough air flow.ĭifferential temperature would tell a lot more than just engine temperature. if the rad is cool and the engine hot, there is probably not enough coolant flow This would go a long way to understand where the cooling breakdown is happening.

I would like to track down a IR thermometer to compare block temp to radiator core temp and see if everything is hot. I still really have my suspicions on the water pumps ability to pump at low rpm.Įdelbrock says high pump rpm is not a problem, claiming that I can spin it as fast as I want within the constraints of the mechanical pulley ratios.

It does move a ton of air, I think it and the pump is just running a little slow at idle.Īs for engine compartment space, it is pretty plentiful, this is a full size car. The present fan is a 6 blade solid steel unit. The older mustangs have about a 5 inch unit. The present pully is 6 1/2 inches and I know there are smaller stock ones around. Seriously, back to the very fist post, I want to try a smaller water pump pulley to increase the fan speed relative to the crank. RE: Water Pump Pulley Sizes for Early Ford Engines patprimmer (Publican) 15 Jun 06 12:22 A 1.5 inch magmeter would be sweet but $3K is a little rich.Ī household water meter might work, but I don't have one and am not too sure how well it would deal with 100☌ coolant. I would love to finish edelbrocks work by installing a flow meter in the radiator hose, any smart ideas to measure flow in a rad hose for cheap. (yeah yeah I know, I have just been busy. an op amp / resister network? I haven't gotten to installing a proper water temp gauge yet.

The clutch should lock up during any hot operation provided water flow is happening and the rad is hot.Īny clever folks out there know how to make a RTD work on a DVM with a minimum of parts? i.e. The thought on the clutch fan is to return extra HP at highway speed / cool conditions. I may also switch from the 1971 steel fan to a 1976 steel flex fan of a newer LTD. I will add a clutch fan if I can hunt one down. I think I will hunt down a pulley that is smaller for the water pump, therefore increasing the base rpm of the pump and bladed fan, leave the crank pulley alone, since it runs the ps pump too. This is what leads me to believe that fancy pump I just bought is not pumping adequatley at low rpm. Only when I am jockeying around in a camp spot is the overheating occuring. Ironically as long as I am moving or on high idle everthing is fine from a cooling aspect. To enhance the story some more, the motor is in my 1971 ford LTD and I am using it tow a 30' 6500# holiday trailer. I have some suspicions that the edelbrock pump is made for those in mind that idle their overcammed engines at 1500 rpm. Interestingly enough, the stock pump with the cast impeller did seem to perform more reliably at low rpm.
