It could cost between 300 dollars and 600 dollars to replace the radiator in a 2003 Kia Optima. This varies with the type of radiator chosen and your location.
InstructionsDifficulty: Moderately Challenging
== * Resealable container * Replacement radiator * Engine coolant * Distilled water Step1 Disconnect the negative battery cable before you begin. Loosen the drain plug on the bottom of the radiator and drain the engine coolant into a resealable container. If you loosen the radiator cap, the fluids will flow faster.
Step2 Unhook the radiator inlet hose and outlet hoses, and disconnect the oil cooler inlet hose and outlet hoses. Disconnect the connector on the fan motor and the clamps on the fan shroud's wire harness.
Step3 Remove the fan mount bolts and the fan, along with the motor, and pull the radiator assembly out of the engine compartment. Detach the fan from the old radiator and transfer it to the new radiator.
Step4 Slide the new radiator carefully into the engine compartment and tighten the bolts and claps on the radiator and the fan.
Step5 Reconnect the clamps on the fan shroud's wire harness, the connector on the fan motor, the oil cooler outlet and inlet hoses and the radiator outlet and inlet hoses. Reconnect the reverse battery connector.
Step6 Fill the radiator with a blend of half engine coolant and half distilled water, pouring slowly to avoid air build-up.
Step7 Start the engine and let the car warm up to bleed air from the system. Turn off the engine and top off the coolant level.
* Be environmentally responsible and reuse engine coolant if it isn't too old or contaminated. If you choose not to reuse it, take it to a garage or hazardous waste facility where it can be disposed of properly. * Be sure to keep engine coolant in a sealed container out of the reach of children and pets, and if any is spilled, clean it up immediately. Remember that antifreeze tastes sweet, and can be fatal if ingested. * Wear protective clothing, gloves and eyewear when replacing the radiator in your Toyota Camry. Never open the radiator cap if the temperature of the engine coolant is 100 degrees or more, as serious burns can occur.
Honestly if you don't know where the drain plug is, don't mess with the vehicle then!
I had the same probleme. Finally I had to push down again and turn counterclockwise again and Bingo I got it out ! Answer 1 is correct, but did not explain that the cap was NOT "jammed." In the "old" days, radiator caps could be removed with a single twist to the "open" position you mention. However, the pressure of the coolent in the radiator, would often "blow" the cap out of your hand, and scald your hand, arm, and possibly your face and other parts of the body. This was NOT good !!! For SAFETY, radiator cap manufacturers designed a "DETENT" lock into caps which allow you to loosen the cap just far enough to allow the hot pressurized coolant to flow through the "overflow" tube to the coolant recovery tank. When you turn the cap to that detent position, it CANNOT blow off, nor can you remove it. By design, to "override" the safety detent lock, AFTER there has been time for the presure to neutralize, you must FIRMLY press the cap down, and THEN CONTINUE to turn the cap another 10 to 20 degrees of rotation, in order to clear the safety lock tabs, and THEN lift the cap off of the radiator filler neck. Hope this helps many. j3h.
drain plug radiator 2000 legacyCrawl under vehicle at the bottom of the radiator on passenger side you will find it
Unlike other cars' drain plugs that look like WING NUTS, this looks like a fat plastic screw that is driven (and loosened) by a big fat Phillips screwdriver.
Another tip: It is almost flush with the bottom of the radiator surface (that is, it does not stick out, it is kind of recessed), and it goes in and comes out in the direction of straight up to the sky (unlike some that unscrew on an invisible line that is parallel to the ground and in the direction of out in front of the car).
Another tip: To get at the drain plug, your fat PHILLIPS SCREW DRIVER has to get around a piece of plastic moulding that is just beneath the radiator. You will approach the drain plug from the aft side of this moulding. To make it easier, melt a 1/2-inch hole in that molding by heating a fat bolt on the kitchen stove, held by a pair of vice grips, until the bolt is red hot. Then walk out to the garage, lay down with your feet out the front of the vehicle, and on the passenger (right) side of the radiator, push the hot bolt thru the soft plastic in a pre-selected location that you have confirmed - with a flashlight - is just under the drain plug. Now the process of unscrewing that plug will be a 10-second job and very, very easy. Or, if you don't want to melt that access hole, use a short stubby 3-inch long PHILLIPS SCREWDRIVER instead of a standard 7- or 9-inch one.
