I have a Dodge Caravan 2000 w/ 3.0L engine and changed the coolant in the summer. The hardest part was getting the drain valve out and back in again. The drain valve i located on drivers side lower portion of the radiator that faces the driver. You can access it through the top and reaching down to get it. use a pair of pliers but nothing that locks on.
The drain valve is made of plastic so be careful. The trick is to push the drain valve in and then turn it before it will come out. I found that i had to push the drain valve in with considerable force before it would release. If and when you get the drain valve out, you will want to make sure the little rubber gasket around the drain valve is still in good condition.
Mine wasn't and i had to replace it. I found a suitable gasket at a department store automotive section. It came in a package with a bunch of other different sized gaskets (had to buy the bunch). Anyhow, you may have to push the drain valve in and then turn it before it is in properly.
Other than that, make sure you use the proper coolant and mixture for the climate you'll be driving in most. the owner's manual will give you an idea of how much coolant it will hold. i went through about 10 liters to fill mine up. I'll admit that changing the coolant was frustrating at times and i spent a lot of time getting together everything i needed and properly disposing of the old coolant. It was a learning experience. I saved myself some money but i think next time I'll get someone else to do it for me.
When the engine is cold you can add to either the radiator or the coolant recovery bottle.
in the coolant resivor
On the back side of where the upper radiator hose hooks to the engine.
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
Two wire sensor very near where the upper radiator hose hooks to the engine.
The engine coolant temperature sensor is the two wire sensor near where the upper radiator hose attaches to the engine.
Two wire sensor, just behind where the upper radiator hose hooks to the engine.
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
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!!!
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.
The coolant enters the engine by way of the lower radiator hose and exits the engine by way of the upper radiator hose.
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.
A storage tank for the engine coolant. Air flows through the radiator helping to keep the coolant cool.
It is a flexible conduit for the coolant to flow between the engine and the radiator.
burn that pos wow you can do better than that where is the coolant temp sensor on3.3 engine on a 98 dodge caravan
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.
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.
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.
coolant pumps pump the liquad throw the engine and back into the Radiator
In the radiator in the front of the engine
is coolant leaking from engine?or is it leaking from water pump and running down engine and appears to leak from engine
On the radiator side of the engine.
it should be in one of the coolant lines leading up to the radiator.
As coolant cycles through the engine, it absorbs heat from the engine, after which, it continues through the cooling system back to the radiator. As the coolant passes through the radiator, the heat is exchanged to the ambient air by way of airflow through the radiator fins (this is why it's important not to bend the radiator fins).
