Leaks are the most common problem that hinders a Pontiac GTO heater core. Many of the resulting symptoms are observable from inside the vehicle. If the core blows up, it causes warm coolant to leak into the cabin, usually forming a puddle on the passenger side that produces a sweet smell. Come to AutoZone for a heater core replacement for your Pontiac GTO to ensure you're provided with the right products at the right price. The trustworthy advice provided by our helpful staff is available to answer any installation questions you may have.
