    coolant explosion leak

    So three days ago I changed my timing belt water pump etc. Since then I have had zero issues until tonight. The. Car was smoking under the hood but not over heating. Popping the hood it smelled like hot coolant and there is coolant visibly all over the underside. Of the hood close to the radiator cap and overflow tank. My guess is the line running in to the overflow since it (the overflow) keeps running low. The other two caps have a good level consistently when checked and I see no visible cracks or leaks in the lines running along the top of the radiator. Any ideas why I have coolant spewing under neath the hood in that area. And to double check there are no o rings on the insert line for the overflow right?

    The overflow is not under pressure and there is no clamp necessary for the line to the white plastic container.

    Sounds like the radiator cracked. Common problem. Rev the motor with the hood open. If the radiator is cracked it will spew out fluid.

    +1 - timing belt is probably coincidental.

    Regardless of what the OP's problem ended up being, the same advice applies to your car. You need to get it pressure tested to see where it is leaking unless you can see where it is coming from more easily.

    it turned out to be a crack in the top of the oem radiator on the middle driver side where the plastic and metal meet. I found this out while going to go get the items I needed to do a compression test. I knew I had a leak as you can see in the op but it was not a severe enough loss of coolant to affect a short drive. But on that drive the fissure became worse and the cars temp crept up and I popped the hood and was able to see it. Not the best way to find your leak but I got lucky and didn't harm the engine. I recommend the compression test.

    I just found a hole in the top hose that comes from my rad to my engine, could that be my problem? My engine does not over heat on my temperature gauge, but she definitely smokes heavily all the sudden

    Yes a hole in a coolant line is a problem. Get it replaced. Park the car meanwhile.

    After that, refill from the upper reservoir then fill the overflow to the high line. Start the car and allow it to come up to full operating temperature for a few minutes with the passenger heater on hot and the fan on high. Turn off the car, allow to cool, and refill the top reservoir and the overflow.
