How do you know if your 1995 Geo Prizm has a cold weather package for heater core replacement?

To determine if your 1995 Geo Prizm has a cold weather package, check the owner's manual for any specific mentions of the package or features related to cold weather enhancements, such as additional insulation or a more powerful heater core. You can also look for a sticker or label under the hood that indicates the presence of a cold weather package. Additionally, inspecting the heater core itself for any modifications or variations in size compared to standard models can provide clues. If in doubt, consult a dealership or a qualified mechanic for confirmation.
