    There are 2 in the BACK of the engine block,between the transmission and engine. There is 2 on each side of the engine block just below the heads and 2 of those are hidden behind the motor mounts. There is also 2 in the front of the engine that you can't see until you remove all the brackets on the front. That makes 8 all together. i was under the impression there wher 2 in front? just wondering where so i dont have to tear down everything of the engine

mmmmmmmm they are really hard to replace but most likelly is goin to be a intake gasket, i do recomend you to call arrown the auto repairs and ask for a pressure test to the cooling system
this test is not that expensive and will tell you exactly where is the leak coming from, but on this type of vehicles i badly see a freeze plug leaking.

SOURCE: Steam came in from vents and high pitch whistle

start the enginemake sure the radiator is full with the cap oon tightly and open the hood and let the car idle in the driveway untl it starts to team, this way you can locate where the steam is actually coming from.
when it is overheating is there white smoke coming out of the tail pipe?
if there is this is a good sign thatyou have a blown ead gasket.
the other thing that couldbe causing this over heating is a plugged catalytic converte.
to rule out whether it is the themostat sticking or not. remove the thermostat from the car put it in a pot of boiling water on the kitchen stove and see if it opens or not. the boiling water will make the thermostat open if it is working properley. Be sure to pay attention as to which way the thermostat is pointing when you remove it so when you put it or a new one back in that it is facing the correct direction. if it is not facing the rite direction it will not open and cause the car to over heat.

Why is car pouring out anti-freeze from behind the passenger side front tire; running hot after about 15 mins of driving at speeds over 40 mph. I removed the thermostat & refilled with anti-freeze

when it is pouring out. why didn't you open the hood to see where it was coming from. if its coming out of the overflow that would be easy to see.

Coolant leak behind motor

No, on the freeze plug. A freeze plug leak would immediately start leaking as you were pouring coolant into the radiator. And would be leaking constantly, whether engine was running or not. More likely a head gasket, or if there is a coolant passage into your intake it might be an intake manifold gasket.

Had to replace radiator, also replaced two hoses. now it still seems to be needing anti freeze and is smelling like the motor is running hot still. have not seen any leaks as of yet looked while van was...

If you are still adding to your system its still leaking-could be a head gasket. Open the radiator cap while the motor is COLD and start it, then look to see if there are bubbles in your radiator. Also check your oil dipstick and if you see foamy or wet oil/water mix you have a head problem.

2000 dodge caravan 3.3L is over heating

Hello, If your car overheats and damages the engine, you have no one to blame but yourself. Keep your eyes on the temperature gauge and never let the needle move into the red. Pull over before it gets too hot. And to resolve this follow this steps:

1. Turn off the engine.

2. Wait. If the engine is steaming, don't open the hood.

3. Pull the hood release lever under the dashboard to open the hood when the car has cooled completely.

4. Walk around the front of the car, reach under the hood, find the latch and squeeze it. As you squeeze the latch, pull up and open the hood.

5. Check the coolant reservoir tank first. It's a plastic jug that has a small hose running to the radiator. The reservoir can be filled when the engine is hot (except on German and Swedish cars, the plastic reservoir is also under pressure, so don't open when the engine is hot).

6. Open the radiator cap with a rag. Remember: open it only after the engine has completely cooled. If you're not sure, don't open the cap. If you open the cap while it's still warm, you may burn yourself with steam or hot coolant. Open the cap slowly, as if you were opening a bottle of soda that has been shaken up.

7. Examine the radiator. Look inside and see if there's coolant left. If needed, fill to the top of the radiator.

8. Put the radiator cap back on.

9. Check to see that the upper or lower radiator hose, or any of the heater hoses, hasn't burst.

10. Restart the engine.

11. Watch the temperature gauge obsessively. Don't let the needle go into the red. Turn off the engine if the gauge approaches the red zone.

I have a 98 silverado, every morning i find antifreeze on my garage floor, but cannot see anything under the hood on the motor, nothing looks wet etc. on the floor it is up front more towards passenger...

Might want to chk. your freeze plugs on that side along with checking the hoses and water pump, paying close attention to the one behind the starter, it can leak there and run along the block to the front.

No heat and leaks antifreeze

you're on the right track. grab a flash light and crawl under your truck to look for trails left from coolant leaks. if this is happening only when you turn your heater on, but the engine runs fine and there's no leak any other time, it's either you're heater core, or just the hoses going to it. look above the exhaust pipes, all the steam rolling out from under the hood is the coolant hittling hot exhaust or the hot engine.

  1. Sometimes the steam from under the hood, because it is over heat.

  1. Check the water hose include the heater hose, it is a smaller hose behind the engine on the top near the back of the hood, find out which hopes is leaking.

  1. If the hose is OK, check the freeze plug on the engine, because if the engine is too old, maybe the plug was rust and leaking, when it’s leaking, the engine is hot, you will see the steam under the hood.

  1. When engine is hot, you have to be very carefully, do not open the water cap, if you want to open, you have to either wait a while or use a heavy towel to cover the radiator cap, then open it.

  1. Maybe the radiator is leaking.
I hope this can help you a little bit. good luck.
