Thread: catastrophic coolant 'leak' (more like a pouring out)

    Question catastrophic coolant 'leak' (more like a pouring out)

    Hi All,
    Hope you are well. Desperately seeking some help with a new leak I have.

    I've attached photo's of the pipes and section of the engine in question. All coolant related.

    Aside from the throttle body assembly leaking this is a newly discovered leak. Mind you when I mention leak, I had filled the chamber "opaque bottle located on driver side" to 1/2 way before doing my kindy run and by the time I had come back it was empty and while stopped noticed the coolant dripping out very fast from underneath. Seems to only be the case once the engine is hot and when cooled down seems to not leak as quickly.

    It's dripping/running from the underside of the vehicle at blistering rates so I am wondering... the cylinder type shape seems to be where the coolant pipes converge into... is there a seal or something in between those or joining a top and bottom half of that cylinder shape??

    as an interim fix can some silicon be used to seal the two pieces as such until it gets repaired or is it something else that I need to check?? My husband has silicone which can withstand high engine temps...

    I've attached two pics, one of where I think the leak is coming from and the other relative to where it's in engine wise...

    I welcome any advise... my lp is getting into the sick category now *boo hoo*...

    Thanks,

    Lp

    *** edit, i've looked in the RAVE CD and "cooling system V8 > component layout" - I seem to think the problem lies with item #20 but I don't know exactly what item #20 is... so any help appreciated... - thanks :-D

    The cylinder thing you refer to is the thermostat. I wouldn't drive it patched up if you dont have too.

    if its leaking from the join, order a new one. They arent supposed to come apart.

    My first thought would be your water pump, the photos show the coolant seems to be coming from somewhere other than your thermostat, but the second photo looks as if it could be coming from the top hose. Do you have a plastic screw head in the top hose that goes over the radiator? These are prone to breaking and were redesigned to fit in the tee junction at the top. It still might be water pump mine went when I was out shopping, I noticed a massive puddle under the car when I came back to it. I had a land rover mechanic in mornington fix it, he was very good and reasonably priced. His business details were: Mornington Prestige, 13 Bennetts Rd Mornington, PH:59736670. I would get it checked sooner rather than later.
    Cheers Matt

    Thanks so much for that, much appreciated.

    At the most my trips to kindy are local and are about 5 - 10k's away from home each way. I only have 2 trips this week. IF I continue filling up / checking the chamber each trip do you think I will be ok still driving it for these short runs while I wait for the part.

    I'll ring some wreckers tomorrow in my area that may have NEW parts, I can't wait for shipping times from the UK to be honest...

    Just another question, do I need any new clamps that attach to this or anything else that you could advise / share please?


    Many thanks

    Lp

    I would first try and confirm which part is at fault, generally people will replace the hose clamps with standard adjustable ones much easier to use and probably more reliable.

    the colours look a bit strange,,,
    the pink could be OAT I suppose,,
    and whats with the green on everything else??
    and the T piece has already been replaced,,

    replace the clamps on all the "red" bits,,

    you could open the bonnet when hot--
    but maybe wear a welders helmet and rain coat??

    The throttle body leak is common enough, just join the two hoses.

    it certainly pumps the fluid out!!

    yes,, new hose clamps,

    Thanks Matt for the reply. Pain in the ar$e isn't it!! I've just inspected all of the clamps and they all seem to be in order, not cracked, split or broken off. They seem to be plastic not metal (unless the metal ones were powder coated black) but they are definately not able to be moved/prised apart (unless I use a flathead screwdriver or the like??)... I've attached a photo of the top "T" section - all appears to be in order. (Let me know if this isn't the top "T" section ok!!)

    I'm aware of Malcolm @ MP, it's where I had it 1st serviced and received a long list of repairs LOL!!! But this is new *sigh*...

    Thanks again for your help :-D

    Thanks Pedro! Yes it's OAT coolant - red nulon stuff that gets filled into the chamber driver side.

    Green - NFI... you tell me as I can't see any green LOL!!!

    With the "T" piece, so it's been replaced?? I have no idea.... or were you making a statement?

    Do you think I should replace the clamps first as apposed to the plastic chamber that holds the three pipes or just do everything?

    "The throttle body leak is common enough, just join the two hoses"

    u wanna give step by step instructions for that luv? I'm a chick !!!


    ** edit** Forgot to mention, when I did open the bonnet I did hear a slight hissing sound coming from the chamber in question that Matt posted earlier which to me sounded like air escaping from somewhere....

    thanks :-D

    Lol

    It might just be me but there should be a bleed screw in the middle of that T piece, coolant looks to be coming from that general area by the splash marks.

    As has been said see if you can work out exactly where it is leaking. Even if you need to use a mirror with it running.

    It could be almost anything, but it looks pretty severe so you should be able to find it.

    Start it up with the bonnet open and see if you can see any more.
