I pulled into my driveway tonight and as i was walking away i saw smoke coming from under the hood, my heart dropped . I ran over and popped the hood and noticed coolant was everywhere. I then saw that there were actual puddles right beside the injectors on the bottom on the intake manifold. I dont know what to do. Lately there has been coolant dripping under the crank pulley after the car has been sitting and sometimes does it at idle. I havent changed my water pump yet but i do have one from a 200sx (ca18et). Would the water pump cause puddles near the injectors. Im goin to take a closer look tommorow. I am just seein if anyone knows or experienced this before.

check your hoses, mine used to leak a good amount while cooling down so i pushed on some hoses filled it up and leaking stopped

Gravity Sucks! That means the highest point where there is coolant means that is what is leaking. Jack up your car and look at it.

if coolant was everywhere something could have ruptured and sprayed coolant near the injectors causing them to pool... there really isn't any coolant lines above the injectors (or even on the upper part of the intake manifold) that could be leaking there. My guess is a hose popped and sprayed up there.

I had an under-the-manifold coolant hose spring a pin sized hole that once it heated up sprayed coolant everywhere until it finally burst on my way home afew months ago (promptly draining my coolant all over the place). Just let the car run for awhile and see if you can figure out where the leak is (if its not immediatly apparent just by looking under the hood of course). Make sure you have enough coolant in the radiator and overflow tank before you start though

I have popped every coolant line except the upper rad hose and the 2 hoses that feed and return the oil cooler. It could be any of them that has sprayed up there, so fill it up, start the car and watch.

It has to beone of those little small coolant transfer hoses off the intake manifold to just below the throttle body. The best thing to do is clean the engine bay up, fill your radiator up with water instead of coolant, crank the car, and let her pressurize. You should easily be able to spot your leak and make the necessary adjustments/repairs.

Thanks everyone, i finally found where it was leaking from. It was a hose about the size of your thumb right under the throttle body that sprung a leak. Now I just gotta get it off. thanks for the help
