    Losing coolant from timing belt side :(

    Okay so my car is steaming whenever i turn it off.

    There is evidence of water being leaked out because it lands in the splash guard that is under the crank pully

    it was NOT doing this before i changed my clutch and my coolant temp sensor.

    IT is not leaking from the sensor, its below the sensor.. kind of like its coming from the housing that the coolant hose connects to. I dont think its leaking out of the hose because the hose is NEW and i checked the clamp on it last night and its secure (not the stock clamp, its a scew driver intake clamp)

    I filled the car with coolant and after a 5min drive i have no pressure in the hoses and can take off the radiator cap. and it was FULL for sure.. im lost

    the only things i can think of is water pump failed and is leaking.. or the lower intake gasket blew (not sure if that would cause coolant leak. not sure why it would blow) or the part that the coolant hose runs too blew its gasket.

    plz help

    also, the car warms up before it starts doing this.. i figured i was all good after letting it sit for a min.

    Waterpump sounds most likely. Your second opinion on that comes from sparkly brass powder/flecks on the rad cap from the bearing.

    some passager side mounts bolts go into coolant passages if not sealed they can leak

    with the 3.0???? this sounds likely if thats how the 3.0 mount works.. when we drained the coolant to do the tranny we let the motor sit pretty damn low and the only mount that was hooked was the passenger side mount. we might of Fed so something up

    anyone have a second on the mount?

    im really hoping its not the water pump. i know its overdue but i was having ZERO issues before the clutch job.. i dont believe in coincidences

    I would carefully check for damaged hoses, when hanging the engine, you can strain them and put a small pinhole leak. Can you borrow a pressure tester? I hear Autozone etc rents them out.

    pressure tester?

    the hose is brand new... i did install the passenger side hose before we finished the clutch but i dont think thats the culprit. The steam is rising from under the T stat.. or right at the T stat. there was no water on the hose when i checked it last.. i guess ill check it again later when i pull of the intake. With the plenum flipped.. its a ----- to get to anything over there. 8 bolts with lockwashers on them makes it even more of a ----- to pull off.. time consuming.

    Yes, its a tool used to pressurize the cooling system to find leaks,

    I would think the O-rings for the coolant crossover tube are more likely... Possibly the bypass hose.

    Could be, if those were disturbed, but thought you could usually just about spot them from the top and side....

    Could also be the crosspipe rusted out in the middle somewhere and it's dripping out the valley.

    this is what ryan thinks too


    the tranny was pulled thus disturbing the coolant tube thats under the lower intake. i might have messed it up. im trying to pull the lower intake but the dizzy is in the way.. im not sure how to remove the dizzy without scewin up its timing

    Second that.

    Also - not sure if anybody else has had this (I can find pics for those who want them), but the factory rear waterpump housing that was on my 3.0L had been corroded from the inside out (where the crossover tube fits in).. it was all jagged with pieces missing / eaten away. It was like the aluminum had acid poured on it. If it is something similar on your car, be aware that the rear housing of the waterpump is a seperate part than the actual waterpump (front housing with pump) when buying parts.

    Hopefully that is not the case on your part.

    WEll you just scribe or paint the diz position and unbolt it, then as long as you DON'T TURN THE MOTOR AT ALL it will be good to put it back, unless you leave it to sit overnight, in which case the lifters can bleed down and the cam settle forward or back a few degrees.

    I would do two things.

    With the engine at TDC (should be able to tell by the front cam). Mark the rotor position with a Sharpie.
    Mark the distributor rotational position with either a Sharpie or a paint pen. (paint pen will likely show up better.)

    Between those two you should be able to R&R the distributor and get it very close to what it is now.

    Re: Losing coolant from timing belt side :(

    i pulled the altanotor off and it let me get the intake off. dizzy is still in

    i dont think the main coolant tube that runs under the lower intake is the cause.

    what is the bypas hose? is it that little guy that is next to the t stat?

    all gaskets look good so far.. nothing blew out. Im lost now. it might be the little coolant hose that is next to the t stat but i dont understand why it would be.

    this all started after i pulled the tranny, replaced coolant hoses, replaced coolant temp sensor. The motor was also sitting at an angle. why would something like a bad water pump just now start giving issues IMMEDIATELY after the car is started for the first time with the new clutch

    Well if you had to baby it on the old clutch, running it hotter and harder testing the new clutch could have provoked it.

    dude, take brents videos of him pinning the limiter and times it by 10. Thats how much hell ive given the car with the stock clutch. no babying here. (okay maybe not more than brent has done but i beat the HELL out of this thing!)

    and yes, it was immediately.. as far as i know, it didnt do this before and if it did, i should have noticed it because it would smoke when i turned the car off at a stop.. you could see steam coming out

    Did you disconnect the bypass hose?
