Driver error. The car is equipped with an idiot light that tells you to shut off the engine if it overheats. They don't call them idiot lights for nothing.

My 91 honda prelude is leeking oil and its smokes when hot but cant figure out where its leeking from

easiest way is to get the dye and poor it into your engine. Then with the dye light you will be able to track the source. On those years the most likely spot was the intake manifold gasket and valve cover gasket. You also could have a blown head gasket that only blew on a oil intake side, doesnt mean that you would over heat

What would cause a 2004 Dodge Caravan to leak engine coolant from both sides of the radiator and causes smoke on the driver side near the coolant reservoir?

Seems the smoke is the hot steam from the coolant. That escapes from your radiator. The culprit would be the radiator cap. The coolant when your engine is hot, goes to your coolant reservoir, and it( coolant ) should go back to the radiator when your engine cools down.
The coolant failed to go back to the radiator because the radiator rubber seal is already broken and suppose to **** the coolant from the reservoir. Coolant also escapes from the radiator, thats why you see some coolant from both sides of your radiator. The heat inside the radiator expands the coolant and the only course is through some crack seals.
Radiator cap have pressure rating that opens its valve in a certain pressure.
Hope that helps you out!
Thanks for seeking help from FixYa!

I have a subaru legacy 1990 and its over heating. The radiator is losing antifreeze but the I'm sure its not coming out of the radiator itself. When it started over heating I seen steam coming out from...

I hate to say it but sound like you may have a partial blown head gasket,do you see any water on the ground or is it just evaporating,fill it all the way up (radiator) then leave the top off and then crank it up,if the water shoot up in the air bout to the top of the hood,this is a way to see if the exhaust is coming through the radiator,how is it running skipping or anything,do it steam excessively when you crank it up,out the tailpipe,like more than it use too,I hope I said something to help you.hopefully the head gasket isn't your problem thanks

My 1998 legacy is overheating, check engine light doesn't come on, could it be the thermostat?

Yes it could, but the cars have a bad reputation for eating head gaskets, so just to be safe, keep your eye on the temp gauge, don't let it over heat, carry water with you. and check for steam out the exhaust when driving, look for oil in the radiator, it will float to the top. A radiator shop can tell you real fast if you have a blown head gasket. We just did one here, found it easier to replace the motor than to do the heads. I have heads if you need them, J25. But on the bright side, could just be low on water. Your thermostat will usually make the engine run cold from being stuck wide open, If it gets stuck in the closed position, it will overheat, pop open the rad cap when warmed up, careful, look to see if the water is moving. If it is, the thermostat is open, will not overheat.

My 1990 subaru legacy was running fine-I went to the store less than a mile away and when I got home something was leaking from underneath the car and there was steam coming from under the hood..i don't...

Just because it was not hot to the touch, does not mean it is not a coolant loss problem----if the coolant is so low, there may not be enough to make the radiator hot (though usually the steam in the system will).
...a stuck thermostat can also let the engine overheat while the radiator remains cool (the fluid only circulates within the engine and is stopped from getting to the radiator.
...likewise a hose could have burst below and let the coolant out, over heating the engine, and the steam going out the ruptured/popped off hose; would look underneath..
...when cool, check the level in the radiator (likely empty),
...and less than a mile away, may not have ever heated the radiator, though usually only a mile to heat up the coolant
...of course there is always sabotage
...and water pump failure, (so no water circulated) causing overheating and no radiator heat, and possibly enough pressure to blow off a hose, but usually the radiator cap relief spring would allow pressure to escape (and that steam would heat up the radiator on the way---but if only steam in the radiator, it would cool off quickly after venting, because no more water in the radiator to hold the heat. all depending on climate,temp and further details , symptoms..
hope helps..

95 subaru legacy l with coolant shooting out of radiator

The cap you are refering to is actually a screw in bleed cap. My first concern would be why it blew out. I can only think of one reason that much pressure would present is,sorry to say, A blown head gasket. The cap is threaded in and unless it had been cross threaded,I can think of no other reason. I hope this helps. Try to have a good day.

Both head gaskets have to be replaced and the heads need to be resurfaced, be sure you go thru the torque specs and sequence correctly, it is a strange process, but has to be done. subaru puts out a product called cooling system conditioner, it's advised to install this.
