    thats not the pump, elbows or the rad hose split near the pump. hard to tell where the steam was coming from.

    Elbows are new aluminum so pretty sure not those. Hoses are original so that may be the place to start.

    grab the water pump pulley with two hands, push and pull the sides, car off of course lol if the pulley moves the pump is bad.

    with a mirror on a stick deal you can look under the water pump and see if the weep hole is wet too.

    sounds like a hose tho. thats aloud hiss.

    if you find it tight to get to the hose clamp, take the coil bracket off. makes some nice room.

    theres got to be a spot on the ground from it leaking out, or in the oil, or coming out the tail pipes.

    It all leaked out while my daughter was driving overheated a bit and went into reduced power mode. She pulled into a parking lot and waited for me and it to cool down. I brought 2 gal of water/ weak antifreeze and filled it back up and drove it the 7 miles home. Never overheated just the nice hissing you hear in the video. Oil looked good. Belts spray it all around the engine compartment but mostly down under coil pack.

    sounds like the hose split on ya. if you think the engine side is fun to get to, you've not looked at the rad side yet. its tight as hell.

    theres a tool to reach in and clamp on them factory pinch hose clamps. channel locks work ( what i used) But im sure the right tool for the right job is much easier.

    look how simple that looks lol

    Nice! I did new hoses on my 03 with a players and not removing anything and swearing a lot. I think I will take the coil bracket off. Hope it's the hose but I'm a little skeptical yet.

    ive had a hose split already on this car, and many other times in the past. they tend to split right on the edge of what they are put on. most of the time you can cut it off and still make the hose reach and clamp it on to keep going if in a pinch.

    I can confirm that I have had my water pump gasket go bad and leak. I was chasing my tail changing coolant elbows and hoses when finally after a few months of just adding water the gasket completely failed and would go empty in 5 minutes of driving. After pulling the water pump off indeed, it was the gasket. The whole bottom portion had blown out. Water pump pulley and bearing were fine. Replaced it with a Gates water pump that included a metal gasket.

    Could a stuck thermostat make it get get hot and puke water out of somewhere and not actually have a hole? My guess is the gasket or hose would go. I have not checked the stat yet but should pick up a new one.

    nice!. now to find the time to work on it lol

    id fill it up with water, fire it up and look for a leak before diving in to deep. if its the hose it might leak before you start it.
