Just a little time and effort and you can have air that doesn't choke you. This LH heater box will put safe air in the cabin, now your mother-in will ride with you again, no you can't reinstall the old one you took off.
Eliminate the risk of carbon monoxide poisoning caused by rusted out Volkswagen heater boxes. Common symptoms of a "bad" heat exchanger are no heat coming thru the Heater Channels due to air loss from rusted tin that surrounds the Heater Box, this combined with excessive noise or the smell of exhaust fumes in the passenger compartment. This is not an area you can skip when maintaining your Air Cooled VW. Our Volkswagen heat exchangers are quality products and meet or exceed all OEM standards.
