Classic Car Cooling Basics Episode 222 Autorestomod

We give tips on radiators, what water to use, which radiator is better for cooling, differences in fans, thermostats, and how to install the fan shroud on the NPD Champion Radiator. We look at cooling issues, and begin the disassembly.

Thanks for watching!

No mention of radiator caps or pressure.

A couple of other tips that help if your cooling is marginal.
#1 Block off all escape routes for air to bypass your radiator.
#2 If using a mechanical fan, check that the blades are 1/2 way into the shroud, but no closer than 1" to the radiator.
#3 Water disperses heat better than glycol. So you can use water with a corrosion inhibitor rather than a glycol coolant. Just beware that you loose anti-freeze and anti boil properties.
#4 Check your ignition timing. Late timing adds heat to the coolant via the exhaust ports. (late burning)
#5 High flow thermostats can help by increasing water circulation/velocity. (Please research #5 before posting an opposing opinion)

Very informative video, and I also always used distilled/demineralized water in my cars cooling systems, but now I'll consider using tap water with 30% additive (as required by the manufacturer). Thank you!

I've got a 73 camaro big block getting ready to install the a.c. system under the dash

Checking the vacuum advance canister is also a good idea if you are running warm. The brand new small block in my '71 Corvette was running hot because the canister on the 15 year old MSD distributor wasn't holding vacuum. A new canister fixed the problem.

Every time I've used tap water in my 90 chevy c1500 it turned muddy rusty color no matter how many times I flushed the system. It wasn't until I started using distilled water that it actually stayed the green antifreeze color. I could not figure out why the antifreeze soulation was so rusty until someone told me about distilled. Now it's been green for almost two years now.

What temperature should upper radiator hose be? Same temp as gauge inside the vehicle? My 1967 Ltd, 390. Gauge says 180, however taking a measurement at radiator hose it’s 230. Car has updated direct drive fan 6 blade fan, new water pump.

That was great information on cooling systems. I always used distelled water with antifreeze. Hard water minerals are not friendly to radiator cores

What do you know about Evans coolant? No corrosion, higher boiling point, etc. Seems great, would like your opinion. Enjoyed your video, great content. Thanks

I thought tubesize was most significant factor in cooling. Take griffin radiators for example. 1.5” tubes to start vs a typically .75” tune. That’s so much more cooling!

Been trying to keep my dd cooler. Under hood and inside. Been searching through your many videos for window tint video. No having too big of radiator can be issue. Here is why some manufactures use too small of tubing in 3 core radiators. See this on AMC jeeps people buying cheap ebay radiators. Buyer beware. It has been recommended to use 2 core radiators of a bigger core width. They usually will have the bigger tubes inside. Not all radiators are made the same. So if you change radiator to bigger radiator and it starts getting hot after change it may be the flow rate of radiator. Too fast and may not cool and too slow and may not cool. Its better to buy from respectable radiator manufacture that will have made radiator for proper flow rate.

I really enjoy your videos, I find them highly informative and entertaining especially to a newbie like myself to Auto restoration. How about an update on the 67 fastback, the Night mistress, I believe it is called.

I am curious as to what the foil is for?

Can you use CLR to clean out a original radiator rather than buying a new one?

[herbnalis]

Down flow radiators don't have problems with the tubes silting up & becoming blocked. Cross flow radiators need to be removed & stood on their sides & flushed with a garden hose as routine maintenance. In Australia there is a brand of radiator called 'Desert Cooler' . It's a down flow radiator that has blocking fins to redirect water to flow in a snake like fashion through the radiator.

[UnapologeticAmerican]

Aluminum is nice. But what if I want to just clean out my original. What do you suggest using? CLR? Vinegar? Baking soda?

[AmpasaurusWrecks]

I've read that aluminum radiators are not as long lasting as original style brass ones, any thoughts?

[ralpha]

i have copper fins with aluminum tubes in my radiator, is that fine?

[Brooklyn_Powers]

Great video! You remind me of: Det. Stan Switek from Miami Vice.
