Massive coolant loss, where from?!

[shalmaneser 26]

Hi guys, need your help on a tricky one.

 

Just finished the cambelt, filled up with coolant, all good. Go for a drive to check I haven't got the timing wrong, it's not going to blow up etc etc. Anyway, all is going well and engine is well warmed through and feeling very strong until I decide to give it some beans out of a roundabout, hit the limiter and the engine promptly explodes in a cloud of steam.

 

Turn the engine off, and coast into a convenient quiet street, lift the hood...

 

All the water pipes around the cambelt area are fine, somehow water is pissing down the distributor side of the block all over the diff. Can't see the source of the leak, does anyone have any clues as to what I should be looking for? It's not the thermostat hose, or the water matrix hose as far as I can tell, it's something else? What else could give up the ghost under high pressure down there?

 

Had to run home about 5 miles, good bit of exercise though. However it means I can't poke around to see what's wrong, so need to make some educated guesses from this end.

 

Plus, as if that wasn't enough the engine is making a funny whirring sound when engine braking, doesn't happen under power or while crusing - I'm thinking clutch release bearing?

 

Bloody car is pissing me off ATM, first the heater matrix, then the water leak from the water pump, now this!!!!

 

Will have a brand new car by the end of this, wish I'd just thrown in the towel and bought a gti6 engine!

Thermostat housing gasket/seal. Mine leaked from here, although only slightly, rather than massive sudden loss.

s-shaped hose from the SAD/temp sensor housing to the thermostat housing? fairly common failure point with the age of them now.

This would be my first suspicion - probably the most common coolant hose to fail, usually on the inside radius of the bend so it's not immediately obvious at a glance. They can go suddenly and in an impressive cloud of steam too, speaking from unfortunate experience...

Sounds likely, what's the deal with replacements? Do BBM do the part, or is it still available from Pug?

[Anthony 1,003]

Available from Peugeot certainly and less than a tenner from memory - my dealer had one in stock last time I needed one too

 

Otherwise, I'm sure that Stew from BakerBM will sell you that hose on its own

[welshpug 1,657]

yes to both

[shalmaneser 26]

excellent - don't s'pose anyone knows the part number do they?!

Your Peugeot man should know!

Your Peugeot man should know!

 

But he's an arse and I don't trust him!

 

Trying to find it on Sarty's engine guides but it's mysteriously absent....

[Anthony 1,003]

Servicebox isn't working at the moment, but I'll have a look later for you - well worth signing yourself up on there though, as it's extremely useful for occasions just like this!

[Anthony 1,003]

Good news is that I've found it on Servicebox, and it's part number 135104

 

Bad news is that it's listed as NFP, so you might well not be able to get one from Peugeot anymore...

[welshpug 1,657]

doh, was only a few months ago that blue haddock got one iirc.

 

stew stocks them though, about £15 I think.

Maybe about a year ago when he still had a 205...

[shalmaneser 26]

Cheers guys will give my friendly local dealer a call to check on the off chance. Doubt the news will be good though!

 

I'm on servicebox, but it's being an arse ATM...

 

BBM it is.

 

EDIT: Found the hose, why the hell is it in the airconditioning section?! Only £7.11, hopefully my dealer can find one.

Sometimes you have to think a little outside the box when it comes to Servicebox - while you'd logically think that it was a coolant hose and thus would be with all the other coolant hoses in the engine cooling section, that would make too much sense, and instead, because it's a hose that feeds the heater matrix, it's in the heating and air-conditioning section

 

I was looking for door hinge pins the other day, and after much headscratching, eventually found them in the weatherstrip section...

[shalmaneser 26]

Top diagnosis boys, it was the hose you suggested.

 

Phoned Pug, unsurprisingly the guy was less than helpful - either way there was no stock as servicebox suggested.

 

Waiting for BBM to get back to me now.

 

Just the clutch to do after this and I might actually be able to drive the bloody thing!
