One other thing, a vacuum filler is a life saver. I have a Lotus Elise where there are numerous runs in the coolant system that trap air. Filling the system without it is a complete pain in the ass!

Turbulators prevent laminar flow and keep the liquid in turbulent flow. Turbulators are tuned to the cfm of the flow. Anything below the minimum cfm and the liquid will remain in laminar flow and the radiator will not cool as well.

Great advice. If I may offer advice not mentioned: A mechanical clutch fan. I had done all of the mentioned tips in this video and my time attack camaro with a stout 383 would always get too hot on track. I had a popular oem electric fan setup on it and rather than spend 500+ on an insane brushless electric I simply bought a stock mechanical fan with thermal clutch. I deliberately left it unshrouded so that vortex ring state would limit hp loss at high rpm. I also went to an underdrive crank pulley. I also was able to duct the "prop wash" out of the hood quite easily. IMMEDIATELY solved my cooling issues and set new personal lap records. Just imagine what even a 3 hp electric motor looks like in size and youll realize no electric fan can really pull much air because they simply don't have enough power to do so. I saved 6 lbs off the front end of the car to boot.

Man that’s so good you mentioned cavitation. My classic ford mk1 escort has a Kent 1600-1700(90tho over sized) that revs to 8000rmp. The cast aluminium coolant outlet on the head shows massive cavities in the alloy after only 1500km of hard driving. To the point I had a smaller crank pulley made. The alternator doesn’t like 8k either, so hopefully that is better now to. If we could harvest cavitations energy for say pre combustion chambers water injection charge, we might be onto something.🇦🇺🤜🏼🤛🏼😎🍀😊😊

Spent forever trying to stop my turbo miata from getting hot on the highway and what fixed it was making an air dam/duct so no air could go around the radiator and intercooler. After like 10 minutes on the highway I would have to pull over and after I swapped it it keeps it cool enough the thermostat doesn’t have to open. I made it out of the same stuff people use for signs in their yard. Like those vote for this senator/ governor ones.

Adding an under tray greatly improves radiator efficiency. Because without one high pressure air builds up into engine bay from under. And this can actually cause the radiator air flow to be so obstructed it actually reversed. Look it up. Don’t spend your fuel catching air in the front of the car. Spend it spinning the tires.

The bleeder funnel with the lid works well with the liquid block test kits - All you need to do is cut approx 1" hole in that lid so the block test kit's tapered rubber bottom fits snuggly. Keep the coolant level in the tapered part of the funnel and use the block test kit as normal. I've gotten best results with this

Great video. We are struggling with an LS in a 350z. We added a swirl pot (Merlin Motorsport - UK), lower thermostat (Summit racing 160), higher pressure cap (Moroso 23-25) and a vented hood. It might be our radiator, so that's next. We bought an expensive Flex-A-Lite (they quit making radiators recently) so we will probably go with a Koyorad next.

A 350z is one of the cars where an air lift is a must because the radiator is so low, we have to keep sucking for about 20 min, run the car and repeat a few times.

I like how the ford FE engines in the Fairlanes and Galxies had the radiator expansion tank bolted straight to the thermostat housing above the block. Zero chance of the heads running dry due to elevation changes. There were plenty of cars during the 80s when their was a push for lower bonnet lines for reduced drag and better fuel efficiency that suffered from overheating and engine damage if the coolant level got low due to having the radiator at or not much abovethe cylinder head height, a risk that the other 98% of the population who arent petrolheads and treated their car as a simple appliance to take them from A to B everyday and didnt keep on top of maintenance.

Oetiker clamps are great. SeaDoo used them in the ‘90’s on the water hoses. The best part is that it gives good clamping pressure all the way around the clamping surface. Only downside that I see is that it is a one time use clamp. Though, compared to worm gear clamp, the Oeticker clamp does not scratch your skin when working near it, or reaching beyond the clamp to access something else in the bilge, or engine bay in this case.

One better than the bleeder funnel is using one of those vacuum fillers. That way I can do a leak down test then flip a valve and pretty much fill the entire coolant system from there. That a Koyo radiator and using a swirl pot and high pressure cap on the pot and I haven't had any more problems with my G overheating at trackdays. That and I put in the Z1 oil cooler and got rid of the stock oil cooler (warmer?) sandwich plate.
