One radiator company is now touting a “revolutionary advancement in cooling technology”. A bold statement like this deserves to be investigated... What is this big break through? it is Extruded Cooling Tubes (ECT) and it is not that revolutionary. In fact it’s not even new, as this technology has been around... [Details]

Copper is actually a better conductor of heat than aluminum. The problem is a copper radiator is not ALL copper. The tubes and fin are copper however they are bonded together with lead, which has horrible heat transfer capabilities. The end tanks are brass and the side channels are steel. The... [Details]

Many companies offer radiators configured as a double-pass or triple-pass design and the name can be a little misleading. On the surface, a double-pass radiator sounds like the fluid goes through the radiator two times and that is not the case. A double-pass design is nothing more than a... [Details]

The key to maximizing the life of an aluminum radiator is not so much the coolant brand as it is the water type. All coolants sold today will protect the an aluminum radiators adequately however distilled water must be part of the package. Concentrated coolants create a potential problem because... [Details]

In the old days of copper and brass radiators this was true. More rows meant more surface area in contact with the fin and consequently a higher heat rejection. So a 3 row was better than a two row and so on. When aluminum radiators came around the rules changed. Cooling... [Details]

Truth be told, there is no such thing. The term “four core” has been misused for decades and accepted for generations. One reason is that very few people know how a radiator works and even less people know how they are made. The term “core” is used to describe an... [Details]

I get asked this question daily and most people stress out over the decision when they really shouldn't. A coolant mixture of 50/50 has a boiling point of 223 degrees. Pressurizing the system will raise the boiling point by 3 degrees for every 1 psi on the pressure cap. A... [Details]
