QuestionSir.
First thank you for the reply. My truck is a 1995 Chevy S10. It now has 131000 miles but the heater core went out at about 110000 miles. I replaced it with a core from Auto Zone and it lasted about 30 days and at this time it started leaking around the water inlets. I replaced it with a core from Advance and this time it lasted about 60 days. I recently replaced it with a core from GM and that is where we are now. The core from advance was leaking around the point where the tank meets the tubes. The beginning problems probably were a result of my failing to service the antifreeze at the proper interval and the system got rust and had to be flushed. Since that time it has been flushed numerous times and the radiator had to be replaced as well. I now have a new radiator, water pump,GM thermostatand pressure cap.
Hope this is enough history. The core in the truck now is brand new from GM and has not yet been hooked up. I wanted an answer to this question first. The reason for the question is that a manufacturer said the electric charge would void the warranty so I thought it be worth the inquiry. Thank you very much for your time...Ray-------------------------

I understand there can be a static charge in the antifreeze which will cause aluminum to be ate up. How can I find and correct this problem? I have a 1995 Chevy S10 truck which I am having problems with the heater core..Thank you
Answer -
Due to the chemical compounds that make up ANTI-FREEZE, Yes there is a VERY SMALL amount of static charge in it.
However this has no bearing on eating up aluminum.
ALWAYS use the type of anti-freeze that the manufacturer of the vehicle recommends and NEVER EVER mix with another brand unless it is only to get your vehicle to a service facility and get ALL the coolant replaced.
Years ago you always had GREEN colr, Toady it could be yellow, green, and who knows what other colors.
Use the manufacturers recommended TYPE of anti-freeze.
What is your heater core problem and what is the MILEAGE of the vehicle and I need it's repair history as well.

AnswerThis is just the reason that I TEST all the parts I purchase PRIOR to installing them. Had you attached hoses to your heater core and held approx 20 lbs of fluid pressure in the component overnight you most likely would have seen a slight leak somewhere. This is WHY these aftermarket parts are so cheap to buy, They are sometimes, If ever, Tested prior to selling them.
NEVER EVER assume that a part is 100% operational just because it is NEW and or REBUILT. ALWAYS test BEFORE installation.
