You ainít kidding, Iíve never done it myself but Iíve read up on it and watched some videos. Itís seems more time consuming than difficult. Wish me luck!

Copper/brass is desirable because it has a wider pH compatibility range than aluminum, so if for some reason your coolant pH gets out of spec, copper/brass will corrode more slowly than aluminum.

Copper is more conductive if you're talking direct contact conduction, but that's not what's happening in liquid to air. Same reason radiators are aluminum, you want to convert air heat to liquid heat in a radiator. The exact opposite but same principle in heater cores?

Radiator and heater core do exactly the same thing, which is remove heat from coolant liquid. Copper conducts heat much better than aluminum. Aluminum is cheaper than copper. Strength and other physical properties differ and result in different construction (tube number and size and fins) for each to achieve similar performance. Both are used in alloy form as well.



I just did quick google search and found articles claiming copper was better and others saying aluminum was better.


When I have to do my heater core, I will care only about which manufacturer/model is most reliable as I only want to do this once.

The OEM heater core is copper and it lasted about 20 years or more and they work great . the new coolants are made for aluminum so if you change coolants it would be better for the heater core .
