Comments about ToughOne or Ready-Aire Heater Core:

Installing this product was a very time consuming process, but I knew that going into the job. Was grateful the part was an exact fit, and did not require any other necessary adjustments. Was a little worried because of other comments on u-tube that said the part did not fit exactly and other steps needed to be taken to ensure it properly worked right. Store associate was very helpful.

              It is a little thinner than OEM. I have not had any issues with it and all seems to OK. I've had no problems with heating my vehicle this winter.

                  The pipes do not line up and this is in no way near the quality of OEM. Think twice before you tear apart your dash (2 Hours)

                      A:

                      The majority of vehicles require the dash to be removed or parts of the dash. However with out the presence of your vehicle we cannot provide you with a 100% answer. I recommend purchasing a Haynes repair manual specifically for your vehicle. This should be able to assist you further into detail on how to repair or replace specific parts.

                      yes it dose have to come down and i recomend take out the fore way switch when u do so dash board tends to hit it and break it when you take it out and fore way switch isnt cheap
