Comments about Ready-Aire Heater Core:

Bought this for our 1999 Jeep Grand Cherokee Limited V8. Followed directions on a two part youtube video. This was a HUGE job! The dash has to be totally removed, and ac has to be dicharged before new part can be installed.

Comments about Ready-Aire Heater Core:

The product did not fit 100% to OEM, but was acceptable. Honestly, I only replaced this part because I was in replacing the AC evaporator core. Figured I would replace the heater core while in there, as it is a lot of work getting the dash out of a 99 Jeep Grand Cherokee.

      A:

      I recommend visiting your local Advance Auto Parts store and purchasing Haynes Repair Manual. The book will provide you with replacing the Heater Core for your specific vehicle. It will also direct you step by step with detailed instructions on the replacement process for any part on your vehicle.
