Some 06-09 Ford Explorers experience failure in their radiators. This article will share some of the things you can do to prevent this from happening, and you are back on the road if your radiator is missing.
Although not a difficult repair, replacement of a radiator has significant associated cost. Ford of wholesale prices on a radiator for 06-09 Explorer runs as high as $ 470 for the one part, and the cost of labor can take to replace the unit much, much higher.
, it is prudent to take steps to avoid replacing the unit is possible. Regular cooling flashes are your best ally to keep your radiator Explorer in tip top shape. I personally am a complete flushing of the machine of my coolant just before each winter. This not only all my cooling lines and inside my radiator as clean as possible, but give me a good time to check my coolant to ensure that it can handle a hard frost. Use a standard antifreeze tester that you can buy at a local auto parts store to periodically check the coolant to ensure that it can handle hard gels in your area. If you think the temperature will drop to 20 below, be sure to note 20 degrees lower than - managing 40 below! The alternative is a cracked radiator, or maybe even a cracked engine block.
One of the most common problems with 06, 07, 08, and 09 Ford Explorer radiators is not with the radiators themselves. It is, rather, with the starter. The wiring leading to and from the boot corrode. When this happens, it is, of course, electricity introduced into the vehicle chassis. Electrolysis can cause coolant to eat thanks to a faster than you can winking radiator.
Ford has a technical service bulletin (TSB) on indicating that each time you replace a radiator on one of these vehicles, you should check electrolysis in the cooling system. According to Ford, you should not ground the heater core in a Ford Explorer 06-09 . Rather, you should check for electrolysis. You check for electrolysis by disconnecting the battery cables, making sure they do not touch each other or the car, put the negative probe of the DC voltmeter on the floor of the motor and the positive probe into the liquid cooling and check to see if you get more. 2 volts in the coolant. Ford says.4 in the TSB, but that is too much for me!
If you experience electrolysis in the early stages, and use a voltmeter to check all reasons. This is long and tedious, but if it does not happen, you will have the same problem again. No company will honor a warranty on a radiator that has been subjected to electrolysis. Once you have fixed the problems causing poor grounding, rinse any coolant.
If your radiator is beyond hope (cracked tank, leaking kernel), you'll need to buy a new one. There is no need to buy a Ford Explorer OEM radiator, as the replacement radiators can be found with better guarantees for a lot less money. Silla is a leading brand and has an excellent heat sink for this application. When you get in, once again, check the electrolysis!
