Hello Matt. About the leaks. When i used to work at the Saab factory in Sweden we also had problems with leaks in the cooling system. It happend when you put the clamp to close to the end of the hoose. The solution was to put the clamp no closer than 5mm to the end. Now days hooses comes with the clamp glued in the correct position. Did notice that some of your clamp was very close to the end of the hoose. Thanks for great content. John

[@float6969]

I'm a pool guy, so I'm familiar with hydraulics. Running pumps in parallel the way you have it MAY cause issues with the flow rates, and potentially even the flow direction, IF the pumps are run at different speeds. If I understand your intentions with the system, they will be, correct? I THINK the effluent side configuration will be OK, but I could see issues with influent side if the pump speeds are running at very different speeds. The pump running at the higher speed could cause the flow through the lower speed pump to stall, or even reverse (not likely unless the pump is shut down completely). In the pool industry, we would employ one-way or pressure differential valves to prevent issues like that. Running the influent and effluent plumbing into common plenums will often resolve the issue as well. Running the influent side of the tow pumps to the lower radiator end cap with separate lines would likely resolve any potential issues. It's also possible it will be completely fine the way it is, lol. Just wanted to share my experience in case you do run into issues later.

[@GingerNingerGames]

I wonder if this might be different in a pressurised system? I've got no idea, I'm just speculating, pools generally don't have the reservoir and lines under pressure. Though then again this might not be under the same pressures seen in a vehicle cooling system

[@float6969]

@@GingerNingerGames The pool itself is the reservoir. When in operation, all of the lines are either under pressure, or vacuum. They are not identical systems, but have common hydraulic design elements.

For a cooling fan... I think you could nab one from a VW made in the last 10 years or so. Most take a PWM input to control speed, then you don't need an external fan controller. Usually they have 2 fans, and the controller is built into the larger fan.

FYI you can get temperature sensors that work at any temperature. It might not be for an "automotive application" but if your temperature is below 212 degrees you won't be dealing with any great pressures you will just be moving the flow. You can basically just tig a bung on a tube and add it in line.

[@thomassvedin8701]

For fan speed many people use the electric volvo fans from volvo 200 700 and 900-series of cars. Cheap fans that can run in two speeds and have an external fan relay. On the fan relay you ground the inputs with an ecu or a two speed temp sensor. The double relay is built to make it that makes it impossible to run both high and low speed at the same time. Popular in many car builds where you want to change from belt driven fan to a high performance fan for a very low price.

[@Zaze09]

[@peterduxbury927]

I love what you have done along the way, to your Jaguar, and I'm not sure if I should be making any 'constructive' comments. Along with all of the plumbing, for the Cooling System, I have noticed that you have used lots of Rubber Hose. The Rubber Hose will not be subjected to high temperatures (110 degrees C) - or even high pressures. But the Rubber Hose will be subject to attack from chemicals, shrinking around those Fastener Clips and more particularly the oxygen in the air will degrade / attack the rubber (cracking) over time. So - with this in mind, I was thinking that Rigid PVC Tube could do a similar job, and there is a variety of sizes - and also different Wall Thicknesses to handle the pressure (if needed). If PVC was used for transporting the Coolant, there would also be no metal clips that could leak around the rubber hose. All PVC pipes and tubes can be formed, and all PVC joints are completely sealed with the special PVC Glue. Aluminium Tube will also require a good Inhibitor, or the Coolant will eat through the aluminium wall thickness. I am thinking that (when the car has been completed, it may be difficult to access those leaking tubes and rubber hoses! PVC can be painted in Matt Black, and clipped to the car body for neatness. I just had to write about this, and gauge some reaction from your Fans. Greetings from Australia.

[@clivematthew-wilson2491]

It's always tempting to weld unique fittings to an aftermarket radiator (I have one on my classic car). BUT, the radiator is probably the most vulnerable part of the drivetrain. If a deer runs out in front of you, or a garbage truck reverses into you, you're in trouble. If you had simply made an adapter for the existing rad, then you could simply organise an immediate replacement, even 200 miles from home. With the custom made fitting on your rad, you'll probably end up coming back home on a very expensive tow truck. Alternatively, you could make an adapter that fits the original rad fitting and simply keep in the glovebox. That way you can forget about this tiresome issue.

[@Callofdootie]

Just appeasing the algorithm. My 2 cents, I would have put one bigger pump upstream of the split instead of two downstream. You could then put a valve on each line downstream and dial in until you get the flow you want/ get fancy and have a temperature sensor on the outlet that alters the valve position. This will remove the need for two pumps and prevent them from fighting/hunting for coolant. Oh actually put temperature sensors on the outlet (return legs) and have them vary pump speed based on temperature. Can you have too much cooling? If not just ignore everything I have said. I haven’t finished watching the video just throwing words at my screen. Keep up the build, great job.

[@andrewshoe6832]

For 20 odd years I have been saying that auto manufacturers need to use the excess heat from the exhaust to run air conditioning, the same way that a gas fridge works. I guess it takes an innovative company like Tesla to work that out. I also think that a small heat exchange cooler would be a good way to cool the air coming from turbos in an intercooler. An integrated heat exchange and turbo is what I think would be a good idea.

[@challigaming5875]

5:25 An Idea for the second Y-Fitting, mabe you could install two checkvalves before it, so the collant dosent move to the other circuit whilst the pumps have different speeds

[@SuperfastMatt]

Yeah, but with a closed check valve, i would have zero flow on one side which wouldn't allow me to measure temperature. I suppose i could install two flow meters and just check flow at different varying speeds. Then I could use that as part of the logic for different flow.

[@davidjulian8536]

If circuit 1. pump is running hard and pulling coolant from circuit 2., circuit two will start to heat up, causing its pump to respond by running harder, thus fixing the flow issue. (I think?). If you do use check valves, the lack of flow in one circuit shouldn't stop you measuring temp on that side, as long as you measure near the heat source.

[@wesleyblackman4356]

@@SuperfastMatt Could run a mechanical thermostat or repurposed electric heater core valve at each outlet. If you have a controlled bypass like a car thermostat you can put the temp probe after or just put the probe closer to the source. That will limit backflow from the hotter to the cooler system. With the open wye you might heat things you don't want to.

[@TheAtzeHans]

You might want consider a fan shroud to prevent air to go around the radiator. This improves cooling and you might be able to switch the fan off while driving on the highway. Fairly cheap temp switches exist that would fit your operating temp but installing a proper sensor is a better way and the rest is just coding.

[@JohnSmith-yv6eq]

A large fan shroud with simple rubber check valves (flaps)around the perimeter... so at low speeds the rubber check valves are closed allowing the fans to work efficiently and pull air in from all over the radiator....and at speed, the check flaps open from the rush of air coming in the grille and through the radiator so the "tight" shroud does not impede air flow...and the fan does not need to run at all...
