Dripping while stationary...


Recommended Posts

All,

Apologies if this is a basic question, my gut tells me that any dripping is bad so I figured I should check on here!

I drove my 1997 GT3 to work this morning, the roads were damp, so the car was wet when I arrived at work. While in the car park I have noticed a wet patch developing on the floor. :)

The drips look to be coming from the the middle of the car (possible slightly to the passenger side) on a level with the front wheels. Around that area, there is what feels like a rubber lined hole which is slightly damp, so I am guessing the drip is coming from there.

The fluid is colorless and doesn't really taste of anything... I would give a smell also, however I have no sense of smell so wouldn't know where to start.

Sorry for the lack of details/names, I am not particularly technical and am still getting the hang of Esprit ownership! :lol:

Does this sound serious? :)

A colorless, tasteless liquid that drips from a rained on car.... humm... what could it be??? :)

Seriously dude, do you think it's wise to taste unknown fluids dripping from you car? Call me crazy...

Well that is what I am hoping, but having had it for 3 weeks now, I am still a bit precious about the car. The bit that made me wonder is that it is still dripping now, 4 1/2 hrs after I stopped.

As for the taste thing... I remember reading that some people on here diagnose their fluids by taste... so I thought I would go with that! Don't worry though, I didn't take a straw to the puddle :lol: merely a little taste from the finger... I probably put worse things down my throat (so to speak) during years at university!

does it have aircon?

<{POST_SNAPBACK}>

Yep, it has aircon, and I would have had it on for at least part of the journey.

Probably isn't related, but when I was over the weekend, mf gf noticed an occasional drip on her foot in the passenger seat. It looked as if it was condensation from what I presume would be an aircon pipe... (it was a bigger pipe up in the passenger foot well) - This pipe is dry at the moment.

Hi Lemon,

I had EXACTLY the same thing on my 98 GT3, if one looks in the middle, between the front wheels you will spy some clips and black rubber hoses, that are connecting to metal hoses, these run to the back of the car, and carry the coolant. Where the rubber hoses contact the metal pipes they cause corrosion, especially if the coolant has been topped up with tap water.

CHECK YOUR COOLANT BEFORE DRIVING HOME, and get your self a couple of lemonade bottles in case you need to top up (not with lemonade!) on the way home. In my case, the leak only occured once the engine was hot, and some expansion occured.

First fix is to try and clean up the area and push the hoses on a little further and secure with fresh clips, if this doesn't solve it, then one may need new pipes, which I believe is quite a big job. My dealer fixed mine.

Anyway, that'd be my guess as to your drips. Good luck!

I hear from a very knowledgable source...

It is likely to be water coming from the Evaporator Drain Tube. This exits under the vehicle in the region that the owner has identified.

There is a 5/8" PVC tube from the Evaporator in the cockpit which drains condensate from the Heater Box. It is not unusual to see water draining from here in the current hot and humid conditions we are currently experiencing.

It is worth checking this before investigating any other possibilities. There is a comment that a drip was also noticed in the passenger footwell which was coming from a pipe in the heater area. This is condensation from a pipe where the insulation has become defective of displaced.

Thanks for everyone's comments... :)

Bibs: that sounds like a strong posibility...

After Bramble's post I went and took another look at underneath the car (my work shirt is now filthy!) and also checked the coolant levels. The coolant looked normal with some overflow still in the other tank. and although the light was poor under the car, I couldn't really find any wet areas around the coolant pipes running down the center of the car.

The only area that felt damp was this hole mentioned previously... as put slightly better by bibs, a 5/8" pipe :lol:

Will have a further dig tonight with the torch and let people know...

Thanks!

I am also having problems with water leaking from somewhere around the front of the car on a GT3, the water leaking is definetly coming from the header tank as this emptys overnight onto the floor but the leak does not seem to be coming from where the hoses attach to the fixed pipes rather further down maybe on the fixed pipes themselves and flowing out of points in the chassis underneath, I was wondering if anyone had ever replaced the water feed return pipes that run through the chassis and how hard a job it was, i am not sure if you can pull them out after unclipping both ends or if you need to access them from below the gear shift protecter plate as i can see no way to them through the chassis below except at either end.

The fact the leak is happening overnight and draining the header tank would point me to it being the feed pipe rather than the return which has to run uphill from the radiator but the feed pipe has to run through the water pump on its way so this must be allowing water to flow through the header tank and pump to the leak somewhere on the fixed chassis feed pipe and allowing water to flow back from the radiator???????.

I am new to owning a lotus so this is all new to me but anyone who has worked with the fixed chassis feed return pipes i would like to hear from :(

Coopelar,

Not sure I can be too much help on this one for replaceing the coolant pipes through the chassis but I did have a coolant leak front passenger side conection to the rad in the inner wheel arch, but nothing as bad as loosing all coolant over night! :D

With that sort of loss cant you jack the car up stick the hose in header and locate the leak ? or even connect the hose direct to one end of the the coolant pipes put it under a bit of pressure and track the spray ?

Obviously you get soaked but it will save blowing up your engine ... :(

Just my thought, good luck.

carl c

with it leaking nowhere near the hose connections my only other option is the fixed chassis pipes but there hidden in the chassis down the entire length of the car underneath, i am going to disconnect it from the engine end and block the pipe fill the header tank and check theres no leak on that part then i think i may get some hose and bypass the entire chassis pipes to the radiator and leave it overnight to see if that part leaks which i suspect it will not therefore pointing to the chassis pipes but i was mainly wondering if anyone had ever replaced these or worked near them because i have no clue other than the workshop diagram how there held in, the diagram shows a bracket and and a anti vibration pad but i cant see these under the car or work out where best to access them. :rolleyes:

Erm I really hope that you do not have a leak in the ali tubes that run through the body as I am pretty sure there is no way to take them out with the body on but I pray for your sake I am wrong.

I doubt it is these though my car was 22 years old and was only showing piting on the ends. Good luck mate.

Like Troy says I really hope its not the pipes through the chassis :) as that would be a super nasty job and surely its more likey to be a fault else where that is more exposed and prone to damadge/decay.

Your idea or running temperory lines sounds like a sensible next step.

Good Luck and fingers crossed !

I suppose I could go over to Keen's house if you are really in a bind about the coolant pipes.

What would you like to know about the coolant pipes?

Ok just a quick update, i managed to get the car in the air on some axle stands and check the rubber pipes to and from the fixed chassis ones, i filled the header tank up as it was empty and literally 30 seconds later i had a waterfall coming out of from near the front end of the tunnel which holds the fixed pipes. All the rubber connections looked ok but the clips need replacing as they have rusted to next to nothing but the leak definetly seems to be eminating from inside the chassis :lol: .

I have been having a bit of trouble getting some hose to try bypass the fixed pipes but thats down to me working nights at the moment but with that final check it should tell me if its them or not which if they are leaves me with a problem, to get them changed by my specialist chris foulds it looks like the radiator has to come out to be able to pull the pipes out (which slided easily when i had a hold of them) , this will leave me with at least a

I really wouldn't run new pipes inside the old and narrow the internal diameter. Esprit cooling is marginal at the best of times and the reduced flow would be risky. Put it this way I can't think of anything much more expensive than an overheat, warped cylinder head and consequent top end rebuild.

Sorry!

Sorry i amended my details i am based in leeds, and yes matkutub this is my main concern as well although my temperature and cooling have been fine besides this sitting at 90 degrees most of the time rising to 100 when stood in traffice and then the fans kick in ( only 3 of the 4 at the moment ), the pipe idea does sound risky but i was not sure over such a length if it would affect it too much.

Have to admit to never having pulled a hose through the chassis of an esprit but... is it that difficult? It appears to be a case of pushing it through at one end, pulling it further under the gear stick and then guiding it through another hole at the other end?

What about using some of the smaller diameter pipe to join the old and the new together at one end and then just pulling the new pipe through?

Good luck!

(Edit) Ignore this post... I have now looked at the pipes you are talking about and they are not what I thought... :huh: I will get my coat...
