How many heater core covers are there? This sequence doesn't make sense.

 

How do you access the the quick disconnect heater hose couplings at the heater core?

There is only one cover.It is saying once you remove the screws you can remove the cover. There is a special tool to disconnect the heater hose.Some parts stores may loan them out if you purchase the part at there store.

 

graphic it basically goes in and releases the tabs holding the hose. The long handle is what actually allows you to get back to the hose.

 

 

  1. Push the heater water hose toward the tube to fully expose the locking tabs.
  1. NOTE: When compressing the white coupling retainer, the Heater Hose Disconnect Tool must be perpendicular to and on the highest point of the coupling.

    Push the Heater Hose Disconnect Tool over the coupling retainer windows to compress the retainer locking tabs.

graphic

  1. NOTE: A slight twisting motion while pulling on the heater water hose may be necessary to assist in the removal.

    Pull the heater water hose away from the heater core tube.

Sorry for the delay. I think I'm ready for this challege now. I'm not sure why the engine cover needs removed (convenience?) but I do accept your answer(s). Thanks, Chris
Thank you. The engine cover is the piece inside the van between the front seats that covers the cover.It usually has 2 bolts on the floor and 2 clips one on each side of the cover under the dash.
