Subject: Re: heater core
My partner at work had the heater core clog shut from Dexcool in his Chevy
S-10 Blazer with the 4.3 liter V6. He is a Diesel Mechanic and he claims
this happens when you do not change the coolant every two years. Strange, as
GM claims the Dexcool is good for 5 yrs. or 150,000 miles!!!! I still like
changing coolant every two years regardless of mileage. Regards, Tony G
