After searching over 40 FORD cars in a junkyard and pulling out many drain plugs which did not seal the drain spout I looked at the original drain plug and saw the O ring was squashed almost to the size of the plastic shaft. I removed the defective O ring and replaced it with one of the O rings on the other drain plug shafts. I reinstalled the original drain plug and refilled the coolant. Then ran the car for 20 minutes with the pressure cap tight on the gas bottle. Results NO LEAKS under pressure. I am still troubled that FORD or no aftermarket parts supplier sells the drain plug for this radiator.

Ford does not sell a $5 drain plug for a 2012 MKZ. Instead they want you to buy a new radiator. RIDICULOUS!!! Has anyone found a replacement which I can get at an auto store or fleebay that will work. Only other option is to find the right radiator in a junk yard. Ford parts dealer said the same radiator is in a MKZ, Fusion, or Milan from 2007 to 2012. My car has a 3.5L engine which is code C on the 8th digit of the VIN. Not sure if other cars with different usually smaller engines will have the same radiator.

Want to replace a thermostat on a 2012 MKZ with a 3.5 liter engine. Some sites show 2 gaskets required. Is that correct? Have replaced many thermostats in Ford, GM, and Chrysler vehicles and have never seen one requiring more than 1 gasket. If 2 are required where exactly do they go? Don't want to drain coolant and open up the thermostat housing and be short a gasket.

AC compressor either does not run or short cycles. Cause, defective AC evaperator thernistor sensor located deep inside plenum and requiring removal of entire dash. Alternative fix, a 20 cent 36K resistor in the 16 pin blue or green connector located right behind the glove box. Open the glove box and gently push in at the rear right and left sides of the box to allow the box to come forward into the passenger compartment. There may be a string preventing the box door from dropping down all the way. You can pull it and dislodge the string for better access to the connector behind the door. There are 2 connectors behind the glove box door. You want to work on the 16 pin blue or green one to the left. You need to get a resistor with a value of 36 K ohms (any value from 30 K to 40 K ohms will work) and place it in the connector. I first removed the plug and found it easier to work with. The pins to work with will be either pins 13 and 15, or 13 and 14. Pin 16 is on the top row all the way to the left. On my car I used pins 15 and 13, the second pin on the top row from the left and the fourth pin from the left. On my connector there was no wire in space for pin 14. On some other connectors you will find wires in pins 14 and 13. the third and forth pins from the left on the top row of the connector. I used a 36 K 1/4 watt resistor. Any wattage resistor will work as there is very little current going through it. Simply bend the wires on the resistor and place them in either pins 13 and 15 if there is no wire in space 14, or if a wire is in space 14 put the resistor in pins 13 and 14. Doing this will fool the PCM which controls the compressor clutch and will allow the compressor to run. Replacing the defective thermistor might cost close to a thousand dollars to remove the entire dash. Don't give your hard earned cash to the Stealership. Do it yourself in less than a half hour. Resistors can be located online or at a store selling electronic components.

Have performed the TPMS Training procedure several times and NO SENSOR on ANY TIRE is detected I suspect a bad TPMS receiver or a blown fuse, Cannot locate a part number or the location of the receiver on any Ford or Lincoln parts website. Car is a base model 2012 Lincoln MKZ.

Have a 2012 MKZ with only 1 transponder key. Owners manual says you need 2 programmed keys to program additional keys. Found this method on the internet. Will it work on the 2012 MKZ? Step 1 Enter your vehicle and put the key into the ignition and turn it to the "ON" position. Leave it in for 10 minutes and 30 seconds. Step 2 Before 45 seconds pass, turn the key to the "OFF" position. Then turn it back to the "ON" position. Wait another 10 minutes and 30 seconds. Step 3 Repeat the above step by turning the key to the "OFF" position within 45 seconds. Then turn it back into the "ON" position. Turn key to the "OFF" position and then back to "ON." The key is now programmed. Turn it in the ignition to check. I assume that 2 keys were originally supplied with the car. Manual says a maximum of 4 keys can be programmed to the car. Does this mean since 2 keys came with the car I can only add 2 more keys to take up the 4 memory slots in the PATS system?

Need a new grille and bumper cover on a 2012 MKZ. Know that most parts from 2010, or 2011 MKZ can be used on a 2012 MKZ. Looking at the front grille and bumper on a 2010 MKT see that they appear to be the same. Are they interchangeable?

Have 2 severely damaged front seats in a 2012 MKZ. What detailed steps can I take to remove the driver and passenger seats from a salvaged car which has no battery power and therefore the seats cannot be moved on the seat track. How many electrical connectors are there to be removed? I believe the heated/cooled seats have multiple connectors. What tools do I need to remove the seats (sockets, Torx wrench, rust remover, etc). Am looking at seats from a 2010 MKZ which I believe are the same as a 2012 MKZ.
