My Elantra just broke down on the side of the road =( First of all, the Elantra has basically the same as the 4g63, only it's 1.8L DOHC.

Here's how it goes... I was driving down the highway and my car all of a sudden started running hot and shut off. I pulled over and steam went everywhere. When I opened the hood, my radiator cap was almost burnt completely off and when I looked under the car, coolant was everywhere. I got it towed home and started messing with it. I refilled the tank with radiator fluid, put a new radiator cap on and I also replaced the cracked thermostat. I started the engine and coolant squirted pretty hard out of my overflow tank. I wanted to inspect this, so I drained some of the tank and found that there was a weird substance in there. It was soft and somewhat gritty, and looked like it had been soaked in oil and grease (any possibility that it would be radiator stop leak or something, I'm not sure how this stuff ends up over time and I have only had my car for around 6,000 miles... previous owner could have put it in there). It was all over the place, I wiped my finger across the opening of my radiator and it was there too; I stuck my finger inside the radiator and it was all in there. It seemed like it coated the inside of my radiator. It seemed like something was clogging up my system and not letting coolant through my engine, thus making fluid come out of my overflow tank. Also, when I squeezed my lower radiator hose, coolant dripped out from the right side of my engine... guessing and sort of hoping it's just my water pump. It wasn't an ungodly amount of water; probably a couple of ounces.

If anyone has experienced or heard of this, please help me out, I would like to get this crap car fixed as soon as possible =) Thanks guys!

Not in the motor oil, the only thing that was out of the ordinary was the grit in the radiator and coolant; wasn't oil though. The engine will still crank up fine with everything in it, it will just force coolant out of the overflow tank and out of the water pump if I squeeze the lower radiator hose.

This sucks =(
 
Technically you shouldn't be able to squeeze any hose with your hands and get coolant to come out of the overflow. (unless you squeeze REALLY hard) This implies bad radiator cap usually, but you said it was replaced. So there seems something inconsistant here...

When I crank up my engine coolant comes out of my overflow, when I squeeze the lower radiator hose, there's a funny squelching noise coming from the water pump and coolant drips out of there onto the ground.

A new update... I never thought of it, but my car has been idling funny... turns out I've been running on 3 cylinders since the break down. I'm not sure what is causing it, spark, fuel, etc., but I need to find out somehow. I removed the spark plug wire from the 2nd cylinder from the left (not sure what # that one is) and it ran the same exact way it did when the wire was on. It was running roughly and I just took off spark plug wires until I found the one that was causing it. Guess I could change wires and plugs and see if that helps. Also, I will be taking the plug out temporarily to see what kind of crap it has on the firing tip.
 
Do you smell fuel in the bubbling from the coolant overflow resevoir? If you do, that's a dead giveaway to a dead head gasket and would perfectly explain why that cylinder is dead (all the good stuff gets blown into the radiator) which was caused when the engine overheated after the water pump failed and leaked all the coolant out...

What a run-on sentence...

Just changed wires a plugs, and there's no hint of fuel or oil in the radiator or overflow tank. The cylinder isn't firing, but I can smell fuel, so I know the fuel injectors are pumping fuel into the chamber. I can't think of anything else that would cause this. Maybe it is a blown head gasket, but how else can I tell? There's no signs except for the cylinder not firing, and it doesn't sound like there's air leaking out of the gasket. =(

btw, nice grammar =)
 
Smell the coolant while it's bubbling. Actually if it's overflowing/bubbling while the engine is bone cold, you know that the head gasket is fried right there (or the head is warped).

You won't hear air leaking out of the gasket, it's too noisy in there to tell...
