I as told that Lincoln did not want to blow hot air out until it as cooler before blowing any air. Same on the heater. I usually rolled my windows don hill driving to help it work faster. Maybe I was being fed a line but that is the mine works in a 2002.
#85 of 109 Changing spark plugs on a '05 Town car
Apr 28, 2011 (9:06 am)
Can anyone school me on how to change the plugs on my '05 Town Car? I looked at it and it doesn't look at all like plugs changes I have done on other cars. The plugs seem to have an electrical "clip" atop a plug tower, which seems wedged under what looks like the fuel rail for the injectors. Is changing the plugs on this care really this complicated? Is it a DIY or do I actually need to take it to a mechanic? Please advise. Thanks to all who respond to this shade tree mech.

What you see is "coil on plug" technology, which Ford embraced in the 90's, and other manufacturers have done the same, however, GM and Chrysler lag behind, still producing some cars with plug wires.
This new technology provides a small coil for every plug, located on top of it. They must be removed first, to get to the plug. Very efficient, no leakage of voltage from wires, no radio interference. More expensive though, and harder to tune up. How many miles do you have on the car? The plugs will last an easy 100,000 miles.

Just did this on my 99 TC. One of the things you should probably do is replace the coils if you're going to the trouble to change the plugs. You can buy a complete coil set (8) on ebay for less than $80 shipped. Dealer price will be about $90/each. Another thing to look for is if you have any oil around the plug boots when you pull 'em off, you should go ahead and change the valve cover gaskets. If you don't the oil will eventually foul the coils and cause the engine to miss pretty bad even if the plugs are brand new. Ask me how I know.... ;-( If it's missing now, you may already have that problem. Changing the valve cover gaskets is not as easy as you might think. I'm a gear head and opted to have the valve cover gaskets done at the local Pep Boys. $400 labor and about $90 for the gaskets (they're not cheap).

That the plugs go for 100,000, I choose to take it to my mechanic who has the correct tools to do the job correctly. If you already have the tools, fine, but subtract the cost of the tools from the mechanics fee and he looks like the choice to change. He also will be observant to find other possible areas that need attention i.e. valve cover gaskets and so on. Also, his work is guarenteed. Who guarentees your work?

mileage is 94k, which is why I am considering the maintenance. It idles just a bit rough when cold but smooths out when engines warms. So, is this something a non-techy can do or should shy away from??? thanks for the help!

I'm a fair mechanic, and I wouldn't even try to do it.

You can do the plugs if you have the spark plug wrench (common) and a wratchet with extension. http://www.lincolnsonline.com/tech/00250.html When I put the plugs back in I use put a rubber hose over the spark plug and get each one started that way by hand then torque them with a wratchet or torque wrench. You don't need special tools to do the plugs, but a torque wrench is recommended. You don't need any special tools (assuming you have a metric tool kit) to do the valve cover gaskets either, it's just that if you follow the shop manual suggestions you have to take alot of stuff off. I think if you look on lincolnsonline.com you can find detailed instructions. If you don't want the expense of factory coils buy the coils on ebay http://cgi.ebay.com/ebaymotors/SET-8-NEW-IGNITION-COILS-1997-2011-FORD-DG508-_W0- QQcmdZViewItemQQfitsZYearQ3a1999Q7cMakeQ3aLincolnQ7cModelQ3aTownQ20CarQQhashZite- m4157108ff2QQitemZ280633577458QQptZMotorsQ5fCarQ5fTruckQ5fPartsQ5fAccessories. Each coil has a plug that clips on and one little bolt that holds them down. After you loosen them up you can usually work then off the plugs. You can do that, just take your time. Now if ANY of the spark plugs shows any exterior oil or on the coil boots (sign of valve cover oil seepage), you should go ahead and have the valve cover gaskets changed. I'd recommend taking it to a shop. As I said before, I bought the coils (already had changed the plugs) and took my car to Pep boys. They will do the valve cover job for about $450 including the gaskets. It's not a difficult job, it just takes some time since you just have to take off a bunch of stuff including the windshield wipers and loosen the brake booster (according to the shop manual) to get to the rear valve cover bolts. After changing the plugs, the coils and the valve cover gaskets my 99 runs great.

Actually the compressor will start "pumping" when there's enough pressure in the system. This typically requires one standard sized (12oz) can of freon, not an entire kit. There is a small amount of compressor oil in every can of freon.
The compressor won't work if there's a blown fuse, electrical short or open, not enough freon in the system or if the AC computer is somehow not working.
