How do you replace the heater core ?

its super easy to replace, and cheap too. take off the glovebox by pressing in on the tab on one side, then undo the little plastic wire thing on the other side and tilt it down and it should pop off. now you can see the little access hatch that the heater core is in. there are a bunch of screws around it, take those off, pop the cover off and there it is! now just undo the hose clamps and it should slide right on out.i would drain the radiator first. let me know how it goes
