1988 Town Car - replace heater coreI have a 1988 Town Car that developed a heater core leak last summer shortly after i bought it. I went to the local automotive store and purchased the mechanicial stripdown and rebuild book, not that it helped at all :( Basically what i did was drain the coolant from the lower rad hose, remove the heater core hoses and plug the heater core inlet and outlet to prevent spillage into the interior while removing it. Now heres the hard part. Remove the ENTIRE dash console, including the steering colum covers, glove box and pretty much all the stuff between. A couple of the lower passenger side golve box mounting frame pieces need to be yanked as well. Make sure to label any heating and A/C vacuum lines that may need to be disconnected with vibrant coloured masking tape and a magic marker with numericial numbers, simply because it can be a nightmare to retrace them all. Taking a few digital camera snapshots of the teardown procedure may prove invalueable if you get lost putting it all back together. After the interior is stripped down enough to release the heater core plenum to pull out past the dash, it can be released by one nut under the hood. Its the one 2 inches over from the heater core outlet hose on the top, under a wiring harness bolted to the top of the firewall (heater hose closest to drivers side) My Town Car only had 1 bolt, but there may up to 3 according to my book. The plenum should release without problem. Remove the 4 bolts on top of the plenum to access the heater core unit.The install procedure is the reverse of the teardown. Because of the numerious things that needed to be removed, what i did was take all the screws and place them into the holes of the removed parts and tape them over to prevent losing/mixing them up, or using masking tape to tape the screws in a small plastic bag directly to the part. I would also like to suggest getting new molded heater hoses, because they will likely need to be cut off the heater core connections.Sorry to say it took me a full weekend of frustration to replace it, but it was definitely worth it this winter :) Dezzz
