Follow the upper radiator hose to the engine. The hose clamp on the end is clamped to the thermostat housing. Drain the coolant through the petcock valve on the radiator, or place a large pan under the vehicle to catch what escapes. It's easier to remove the hose from the therm housing, then remove the housing. (put the thermostat back in the way it came out. Pointy end towards the radiator.) Clean off the old gasket from both surfaces, install new therm, apply new gasket. reverse procedure and top off with coolant.
Ok looking at all different Manufactors, and i have'nt seen one with a radiator drain plug..So if you are tring to flush your raditor, just take off the bottom radiator hose, and run a hose in the radiator, and flush it out the best way you can...Then top it off with a Gallon of coolant, and you should be fine...Goodluck...
Many newer automobile no longer have a Radiator Drain ****. If you do have one it will be located near the bottom of one of the Radiator Tanks in the "Most Inaccessible place imaginable". All you need to do is loosen the Hose Clamp on the Lower Radiator Hose and work the Hose free to drain the system. Be careful not to damage the Plastic Radiator Tank in the process of loosening the Hose.
Things you will need:
Radiator coolant mixture (get from garage)
Radiator flush fluid (also from garage)
Distilled water (Or if your me garden hose water ;) )
Take off the radiator cap when engine is COOL. Find the drain plug located in the bottom of the radiator (normaly hand tight) and let it drain out into a catch container. Put the drain plug back in, follow the instructions on the flush container topping the radiator back up. Let engine run as directed on bottle and then carefuly undo the radiator cap using a rag as not to burn yourself. Then remove the plug again and drain out the flush fluid. Then repeat the process with the radiator fluid as instructed on the bottle.
Hello, perform the following steps in this order:
NOTE: car should be cool, in park and on non sloped surface. NEVER leave used coolant in an area where children or pets can gain access, Anti freeze has ethylene glycol which can be lethal to humans and pets.Used coolant should be immediately taken in a sealed container to a local state certified recycler for proper disposal.
1.Raise front end of car, and place one jack stand under frame of car on the inside of each front wheel.
2.Place a 2 gallon (low profile) bucket under the radiator drain plug. The drain plug will be located at the bottom of the radiator.
3.Unscrew the drain plug and let coolant drain into bucket. (It may be necessary to adjust bucket so no coolant leaks onto the ground.
4.After all coolant has drained from the radiator, tighten radiator drain plug finger tight, then 1/8-1/4 of a turn with a wrench.
5.Unscrew radiator cap and begin filling radiator using 50/50
premixed antifreeze solution.
6.Continue adding premixed solution until fluid is just below the top lip of radiator where cap fastens to.
7.Re attach radiator cap and lock into place.
8.Check radiator overflow reservoir and ensure coolant is between add and full, add coolant as required.
PLEASE VOTE FOR THIS SOLUTION IF YOU FOUND THIS INFORMATION HELPFUL.
Under the radiator on the river side or on occasion the passenger side there is a drain ****, turn it counter clockwise to drain the coolant, open the radiator cap before you do this, refill with long life coolant, this is what the car came from the factory with and is required when refilling system.
