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

User Avatar

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.

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

It is a flexible conduit for the coolant to flow between the engine and the radiator.

User Avatar

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!!!

User Avatar

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.

Place something to catch the engine coolant beneath your 1990 Chevy Corsica radiator. Remove the radiator drain plug with a 9/16 ratchet. The engine coolant will drain out.

No , the engine coolant will start flowing through the radiator when the engine coolant thermostat starts to open ( assuming everything is working properly ) Helpfull

The coolant enters the engine by way of the lower radiator hose and exits the engine by way of the upper radiator hose.

coolant pumps pump the liquad throw the engine and back into the Radiator

User Avatar

When the engine heats up to a certain temperature, the thermostat opens up and lets the coolant flow through the engine. Heat from the engine is absorbed by the coolant, which then cycles back to the radiator. Heat from the coolant is exchanged to the air which flows through the radiator fins, thus causing the coolant to rapidly cool down.

User Avatar

No. When the engine is running coolant is heated and expands. Excess coolant then flows from the radiator to the expansion (overflow) tank. When the engine is shut down coolant cools and contracts drawing fluid back out of the tank to keep the radiator topped off.

is coolant leaking from engine?or is it leaking from water pump and running down engine and appears to leak from engine

User Avatar

The radiator consists of cooling fins around tubing which the coolant flows through. A water pump circulates coolant from the radiator through the engine. A smaller radiator around the dashboard makes up the car's heater. An automotive cooling system has 6 basic components; the radiator, coolant/water, pressure cap, expansion tank, thermostat, and the water pump. When an engine is running, the water pump circulates the engine coolant inside the engine. As the engine heats up, the thermostat opens (usually at above 160 degrees), which allows the engine coolant to be pumped into the radiator, through the top radiator hose. The coolant flows through tubes inside the radiator, and is cooled by air passing over the car's grill. The cooled coolant exits the radiator and reenters the engine through the bottom radiator hose. The pressure cap holds the entire cooling system under pressure, which allows the coolant to reach higher temperatures without boiling. The expansion tank holds extra coolant for the system and allows for extra capacity when the coolant expands with the heat.

it should be in one of the coolant lines leading up to the radiator.

User Avatar

The thread on cap for your engine coolant reservoir is the pressure cap / radiator cap ( the engine coolant reservoir is located on the drivers side of the engine compartment , near the firewall )

User Avatar

Really need to know the year and engine size. But you can check this, Does your engine have 2 lines just above the oil filter that run up the side of the engine and goes into the radiator on the drivers side ? If so then that is the engine oil cooler lines and the tubes in the radiator were the oil flows through to cool the oil are probley leaking into the radiator coolant. IT happens often. WILL NEED TO REPLACE RADIATOR. And flush out the cooling system real GOOD. Did your engine freeze from lack of antifreeze ? If the radiator fluid is cheery red looking then the transmission cooler that is built into the radiator is leaking. REPLACE RADIATOR. GOOD LUCK.

Add coolant, with a cold engine for safety, through the "radiator" cap in the upper hose.Add coolant, with a cold engine for safety, through the "radiator" cap in the upper hose.
