The radiator does not have a drain. You have to siphon it out or pull a hose. I don't know about the block one.
AnswerI have a 1999 4wd suburban, and yes it has a drain on the radiator. When you face the engine, standing in front of the truck, look down on the side of the radiator cowling. You should see the drain under the transmission line where it enters the radiator. The only way I could reach mine was to remove the radiator cowling and use a pair of needle nose pliers to turn the pet cock valve to drain the radiator.Take it to dealer and hope they do it correctly, There is a plug on bottom of radiator loosen and it drains coolant out of radiator, but not out of engine, There are plugs on the side of the engine block that have to be removed to drain coolant out of block. Probably impossible to get to and accidents happen, sorry I hope this helps some.
Engine cool. Open the radiator cap. Open the radiator drain plug. Open the engine block drain/drains. There are two for the V6,one on each bank. Let coolant drain. Close all drains and fill engine with distilled water. Repeat drain. Fill with distilled water again. Drain . Close drains and fill with 50/50 mixture of coolant. Run engine with radiator cap off. When air is completely expelled,refill to top of radiator. Don't forget to drain and refill the overflow tank.
To drain your coolant there should be a petcock ( metal rectangular screw type drain)or plug on the bottom of your radiator ussually near the left or right side of radiator.
If there is a cap on the radiator you can check to see if the radiator is full , and if it isn't , " top up " the engine coolant . Otherwise , you check the engine coolant level at the engine coolant reservoir when the engine is cold and maintain the level at the cold mark
Radiator stores engine coolant for circulation throughout the engine The radiator is placed at the front of the engine and exposed to the atmosphere to keep coolant cool to maintain proper engine temperature
AnswerThe drain cock is located on the bottom of the radiatior on the drivers side. That drains the whole coolant system. Take the cap off the radiator reservoir which is the radiator cap by the way. That allows the water to drain out pretty easily.
It is a flexible conduit for the coolant to flow between the engine and the radiator.
Remove the radiator cap when the engine is cool and add the coolant into the radiator or you can add to the coolant overflow bottle. DON'T remove the radiator cap when the engine is hot!!!
On a 2003 Ford Ranger : The 2.3 litre four cylinder engine has a thread on cap on the engine coolant reservoir , that is the pressure cap / radiator cap ----------------------------------------------------------------------------------------------------- On the 3.0 and 4.0 litre V6 engines , I believe there is a radiator cap on the top of the radiator , but with the engine cool you should add engine coolant to the engine coolant reservoir - it has a cold fill mark
there is no real radiator cap. On the left side of engine compartment there is a coolant jug. This where you would add coolant to radiator.
A storage tank for the engine coolant. Air flows through the radiator helping to keep the coolant cool.
The coolant enters the engine by way of the lower radiator hose and exits the engine by way of the upper radiator hose.
