Aluminum heater cores?

[fatherdoug]

I have been needing to change my old heater core in the '78. I just don't get the heat that I used to into the cab. I purchased a new aluminum heater core about 2 years ago, and have been on the fence about replacing the brass core with aluminum(Enter horror stories here.)

I am not having much luck finding a new brass core for the '78 with factory air.

So........My question is, if a person is anal about keeping the antifreeze in very good shape such as flush, replace on a regular basis, could a person prolong the life of the aluminum heater core?

I would think it would be fine. May even put out a little more heat than the brass one

That's what I am thinking also, Frank. The key is to take VERY good care of the coolant system. Thank you.

Most radiator cores are aluminum now as well

I'd use it

Keep in mind, they make test strips to check your coolant, then you know for sure when it's time to flush and change

Thank you, Charlie. I have access to a full scale metallurgical lab.

Also make sure to use distilled water to help prolong the life of the aluminum.

Very true!

I've used aluminium cores and have never had a problem with them.

Good to know! Thank you.

Aluminum is tricky to maintain ,it is capable of lasting 500 years barried
into the ground if conditions are right!

The right combo of moister & oxygen can cause atralisis on aluminum ,
there for ,aluminum does not like to be smothered with dirt or paint!

Aluminum likes open air or if it has some kind o protectant fluid on it!...
