You have to remove the entire front of the heater case to change thecore. This usually looks a lot easier in print than it actually IS.Theinstructions say to remove the lower part of the dash for access; usually youdon't have to remove the entire dash for this type of service, althoughsometimes it makes things easier if you loosen and remove any components notmentioned in the procedure that are in your way.
This kind of repair can be frustrating, as it involves working in tightplaces and with 1/4 drive extensions and universal sockets to get all thefasteners out, but it IS possible.Here is what I have for the factoryprocedure. I don't know of any shortcuts to make the process easier; if you can'tget it off, perhaps removing the dash completely for more room would be aviable option...
