2017 Cooling Buyer’s Guide

There are two aspects of building a hot rod that can make or break any build … electrical and cooling. Cooling seems to be a constant bug-a-boo but it shouldn’t be. There are an amazing number of ideal products out there, like radiators, engine and tranny coolers, relay kits, and cooling fans, to handle heavier than normal workloads. There are enhanced water pumps, both electrical and mechanical, and superior coolants and additives that really help keep your engine (and you!) cool.

Of course, having the correct parts is an important part of the equation but there’s some homework you have to do first before jumping in. Always make sure that your motor is properly cleaned inside if using an older motor. It’s a good idea to check freeze plugs; make sure the temp gauge sensor is in a place so that the exhaust temps or other “super-heated” elements do not cause the gauge to give you elevated readings; have a properly positioned radiator so that airflow passes through the radiator, over the engine, and out of the engine compartment thereby taking hot air with it; and make sure the fan (electrical or mechanical) has the proper fan shroud (it makes a huge difference!). Another area to check is to make sure that you have enough radiator for your engine (based on cubic inches and power output) and that there is enough radiator opening to let enough air into the engine compartment. It’s always a good idea to position the electrical fan or fans behind the radiator (puller) rather than in front of the radiator (puller).

Well, there you have it; some basic ideas on cooling, an area of hot rod building that is best handled correctly the first time as a poor effort now can lead to dire consequences out on the road.

Painless Performance Products

Installing air conditioning to your hot rod? Need cooling fan relays to operate off of a thermostatic switch when your A/C is on? The dual activation cooling fan relay kits by Painless Performance are exactly what you need. Only a few minutes for the installation and your cooling fan will come on when the engine reaches the preset temperature of the thermostatic switch mounted in the engine head or when the A/C is turned on. Available for single fan or dual fan, with different engine temperature fan activation options for each to work with whatever thermostat you are using.

The Brassworks

For 40 years The Brassworks has handcrafted radiators for restored cars and classic street rods. They pack a lot of cooling in their radiator cores. Fins are made of tellurium copper because it conducts heat at twice the speed of aluminum. Their highly elliptical tube design maximizes the coolant contact area, and the punch and flaring of each fin achieves over three times the contact area found in common radiator construction. Staggering tubes tumble air laterally as it passes though the core and embossed louvers in each fin disrupt the airflow on the fin. Making cores with these features isn’t the cheapest way, so you won’t find them in the discount copper radiators or aluminum radiators but you will in a Brassworks radiator.

Our builders assemble our reproductions alongside an original radiator so they can construct a simple drop-in replacement or build from a drawing to make custom fabrications. Specializing in chops, split cores, angled headers, angled cores, reliefs for fans, tank reliefs, formed inlets, and much more, we can accommodate your specific build needs.

FlowKooler

Engines rarely overheat on the highway due to good airflow and good coolant flow. The reality is most engines overheat in stop-and-go traffic, at stoplights, or at cruising speed when the coolant flow rate though the radiator is reduced.

FlowKooler’s newest generation of Hi Flow Water Pumps have precision-machined impellers with integrated shrouds and a military-grade anodized surface finish. With incremental vanes and tighter tolerances, FlowKooler doubles flow rates at slow speed and idle to reduce engine temperatures as much as 30 degrees. A more efficient flow helps conserve system horsepower by 2.2 percent and increase the block pressure by 22 percent, which prevents the formation of hot spots and steam pockets in the water jacket. A full range of pumps for street rods, muscle cars, trucks, Jeeps, and rock crawlers is available through selected dealers or directly on FlowKooler’s website.

Hy-Per Lube Corporation

High-performance engines require coolant to transfer as much heat as possible. As cylinder head temperatures increase, so does the likelihood of detonation and power loss unless ignition timing is retarded. Under extreme conditions, this can also result in overheating and engine damage.

Hy-Per Lube Super Coolant reduces the surface tension of coolant, allowing it to more deeply penetrate metal surfaces at critical heat transfer areas inside the engine and radiator. This results in more heat being transferred away from cylinder heads and a reduction in engine operating temperatures.

Importantly, cooler cylinder head temperatures also allow the engine ECU to safely advance ignition timing, which results in more horsepower. Street applications running a 50/50 mix run 8-10 degrees F cooler, and racing applications running straight water coolant run up to 25 degrees F cooler. Actual cylinder head temperatures can be reduced by up to 50 degrees F.

Hy-Per Lube Super Coolant provides complete protection from rust, corrosion, and electrolysis. This is particularly important in straight water applications, where there is no corrosion protection being provided by the corrosion inhibitors in antifreeze. Hy-Per Lube Super Coolant is formulated specifically to protect aluminum systems and is compatible with all types and all colors of anti-freeze.
