Water leak?

[TRex]

Hi
 Can someone shoot me a link with photos/explanation of the cooling system run/piping on the 13B REW engine please...

 Basically I think I may have a slight leak near the turbo area, after a big run seems to leak coolant, puddle on floor after half an hour or so!
 
 No it is not the expansion tank etc, all undertrays are off the car so I can trace the leak better.

 Looking at the front Turbo, I see there is some piping going to it so also asuming that it is also water cooled as well as oiled?

 Anyway, this piping seems to be corroded a bit and I suspect thats where it\'s coming from, cannot see to well as it is in there..
 But before I removed surrounding bits to have a better look, it would be nice to see a setup of the water lines around the engine to have a better idea what to look for and where to trace from and to.........

Sorry to hear about that mate.  Just posted one up too as mines also desided to loose coolant (must have been writing them at the same time!)  Hope its nothing major for you.

Thanks m8.....

 Should not be something big as it\'s better to have an external leak.  You know what they say, \'better out than in... \'

 It\'s just that it looks like a crappy place where it seems to be ****ing out from and would like to see exactly whats around that area with regards to piping etc for a better idea and understanding.........

 With regard to your prob and your photos, it looks like the AST and tank area. So could also be the common fault of the tank splitting.
 
 New to these machines, so hopefully some nice person that knows what they are talking about will be along soon to set us right....... :god

Thread still here>>>>>> :wiggle

They are at the back as shown.  IIRC the hoses can be removed without removing the turbos.  All the pipework / airpump need removing to get to them though.

I have EXACTLY the same symptoms. I even removed all the Turbo heat shields to try and see where the leak is. WHile I was down there, I noticed I had incorrectly (previously) fitted the turbo oil return gasket.

At least I think I have fixed the oil leak.

I do have a little leaking from the inlet manifold gasket, and the radiator. :-(

[TRex]

Thats what I\'m talking about!!

 JON, thank you very much sir............ :cheers

 I see those pipes look corroded similar to mine and exactly where you have circled is abouts where I suspect could be leaking.....
 Airpump already off, hence why I can see them! But thats about it, I can only see them and they look a bugger to get at without removing more stuff!!

 Anyway dude, thanks again for that photo as thats exactly what I was after...
 This is what this club is about....... :yes

[jonrx7uk]

No probs.

The turbo to intercooler \'Y\' pipework needs taking off (the photo actually shows it on the wrong way round? dont ask).  to do this you need to take off the 2nd turbo inlet pipe.  Its a tight squeeze but it does come off if you loosen all the bolts for both pieces (i loosened the clutch pedal bolts in the footwell to help me and loosened the brake servo heatshield).

Let us know how you get on.

Cheers

Cheers, I\'ll tackle it by the weekend and let you know how it goes...
 
 Funny thing is, took her out for a blast today and not leaking now somehow! :rolleyes:

 BUt will still have a hunt in there as the pipes does seem a bit unhealthy.. I have some lenghts of new hose, so may as well replace what I could with new clamps etc.

 Rgds

Took a blast today and can confirm the leak..
It\'s exactly where I thought it was....... yes in a right bastard of a place! :mad:

 Look like the Turbos, manifold assy may all have to come off.

 It\'s where the arrow points to in the photo below, the pipe has a pin hole leak and after a big hard run with the temps up, it sprays like a mutha......

 If anyone has a simpler idea how to get to the pipes(remove them) without taking off the manifold assy, then please yes!
 
 Thinking a quick fix of putting some metal epoxy around there as I can just about get in there to do that... but it\'s gonna be taking some serious heat around that area..... hhmmm....

Yoh boys slow down. Both pipes can be done without taking the turbos to bits. I had the same problem and took it nice and slow.
The first pipe is under and to the rear of the bracket that holds the intercooler piping ( grey plastic pipe with two bolt holders one on either side ), it bends to the right and down. Remove the cross brace ( the one from the suspension bolts ) then remove your intercooler pipe connection into the turbo. You should then be able to see a small upright  right angled connector which comes out of the top of the thermostat housing, it is situated behind the filler cap. This is the first pipe to replace. Pull/cut if off both ends. It\'s tight but you can clean up both ends of the pipes that the rubber hose connects to. Now slip the new pipe over the pipe that is down and to the right. DO NOT RE-USE THE SPRING CLIPS FROM THE OLD PIPE. Slide a new jub/clip down and do it up. Now slide another one on and fix to the top right angled connection. Thats the easy one done. The 2nd one is to the left and down towards the bottom of the thermostat housing, same type of angled connection and a very tight other pipe. This pipe should have a heat covering sleeve on it KEEP IT don\'t cut it off.
Remove both ends of the pipe and clean up both ends of the pipe. Fit the new pipe to the pipe connected to the turbos using the same method as above REMEMBER TO SLIP THE RUBBER HEAT SHIELD back onto the new pipe before fitting the last j/clip.
Job done. TIP--- also check that the coolent level sender plastic nut with the wire comming out of it is not also leaking. It\'s difficult to see if it is as it\'s so near to the main rad feed pipe junction under the thermostat. My one had been tightened so much the plastic thread had twisted off, i changed the complete sender. You may get away with unconnecting it\'s wire junction and removing it replace the washer DON\'T TRY AND GET ONE FROM A DIY SHOP THEY DON\'T FIT get a mazda one it does have a part number. The other place i found a leak was the thermostat it\'s self i was going to replace it anyway so having taken it off i discovered that the water had been leaking from this flush plate seal area so i cleaned up the seating hole fitted the new one and sealed the flush joint with high temp sealant. I no longer have any leaks. Hope this helps.

I think TRex is on about the actual metal pipes on the turbos themselves as opposed to the rubber pipes (replace these anyway).  Looking at the position of them on the turbos, it looks like the turbos have to come off i\'m affraid...  as they are right at the back under the LIM.

Good Luck

Jon

When the rubber pipes leak you don\'t see any fluid as it evaporates with the heat from the turbos. It may well be the pipes, try it first, before replacing everything. Process of elimination.

[TRex]

Warthog thanks dude... Trying to understand exactly what pipes you are talking about.  
 I am talking about the water pipe that goes to the Turbos for cooling them...  It\'s the pipe I have pointed to with the yellow arrow.
 As Jon said, the position is pretty close to the engine and lower intake manifold and sod all room to get anything in there insitu.
 
  If they are the same pipes, then fantastic dude, I\'ll give it a go from what you said there, no probs......... thanks

Got some very high temp metal-set epoxy, but I prefer to actually do a permanant fix as 1/  more of that pipe may be corroded and rupture again. 2/ Don\'t want to take chances with cooling system!

 I\'ll tacke it in a few days and if it gets serious I\'ll take snaps as I go along for someones future benifit........

 By the way, anyone got a decent set of these pipes they wanna get rid of? :p

[TRex]

Ha, we posted at the same time........... :p

 Yes I am 100% positive where the leak/hole is now......
Exactly where I pointed to on the photo....
 It is deffo the METAL pipe thats ****ing........................
