Hi all,
I am rather annoyed with the D2 today. When I bought it a little while ago it had no inhibitor in the radiator water. So I went out and put some cooling system cleaner throught the whole thing, Loctite branded powder from Repco. Flushed out the system well and truely then added $70 worth of red OAT.
Whilst trying to bleed the system I broke the little plastic valve in the STUPID top radiator hose. So I bought a brass one. While trying to get the broken plastic bit out, the part inside the hose came away from its mount. Top hose now useless. So off I go and get a new top hose, complete with plastic bleed valve....
3 hours later I have managed to recycle most of the expensive coolant and get the new hose on. (minus some bark to the hands and a few dollars into the swear jar!)
I get to work this morning and there is a bit of overflow under the car...not too much to worry about, perhaps its overfull. Nope....several hours later there is a flood and expensive red coolant running down the right side of the engine into an ever increasing ocean in the car park.
I can't find where it is coming from....any ideas? Did the system cleaner eat a hole somewhere? Did some of my sharp tongued comments of a highly derogatory nature directed at the car yesterday come back to bite me?
What a PAIN!!!!

OAT coolant will find any leak in an engine that has been run with either no coolant or glycol coolant. There will be gaskets weeping all over the place. I hate the stuff. It should only be used in engines with all hoses and gaskets in as-new condition, or to replace existing oat coolant.

Damn it...........
Recomendation? Do I flush the stuff out right now and put stop leak and green coolant in?

Wel, it's the quickest way to get it mobile. It may cost you a radiator rod out sometime in the future, keep an eye on the temps.
A friend of mine had a new engine run on green coolant for 12 months, was told to use oat with his new ally rad, I ended up putting a new head gasket in and cleaning every hose barb made of cast aluminium, and replaced a couple of hoses.

It cant hurt to fill in just with plain water or demineralised water for a few days or so while you sort out the leaks, when sorted add the red stuff.
Mine leaked from the fuel cooler inlet on the drivers side!

I went through a long process and now have no leaks, was not easy but was worth it.Originally Posted by Richard93Vogue
I had a leak on my radiator and my top hose, replaced my top hose, and my radiator leak got worse, replaced my radiator and my heater matrix sprung a leak. Must say that my TD5 has 290 000 kms on the clock and had Green Coolant in when I bought it.
IMHO I believe that if you are having troubles then bite the bullet and do all your hoses.
I have now replaced every single hose on the TD5, as well as the Heater Matrix, the radiator. I cleaned every metal pipe that a hose connected to, I flushed the system multiple times. I am now (touch wood) leak free for 1 month.
I have noticed corrosion in a few areas, and I have bought a new water pump, a new fitting and gasket for where the Top Hose attaches to the head, and I am looking for a well priced Oil Cooler Housing.
Once I have the Oil Cooler housing I will replace all of those, with many hours of annoying labour.
I suppose the moral of my story is only use the Red OAT, and check all your hoses, remember as you fix one leak the pressure in the system will just look for the next weak spot

The leaks that sprang up all over mine after a new radiator replacement were genarally as a result of corrosion on all hose interfaces. I've ended up taking off most of the hoses, wire brusing the spigots and giving them a thin smear of hylomar to smooth out the surface and then put it all back together again - the only hose I've had to replace was the water pump to coolant rail at the botom - the ends became too flared for re-use. I've also done the fuel cooler o-rings as well - that was untraceable when warm but appears when the engine's cooled.

Mine started to leak everywere like a sieve after repalcing the coolant from green back to red. It was coming out of the hose clamps everywhere and out of the fuel cooler on the side of the motor like it was going out of style. I just kept topping it up and the leaks have almost completely sorted themselves out now - I just mop up a drip in the mornings to keep the dog out of it and thats all. Don't go over the 60% recommended OAT mix as that makes it worse.
Cheers

Just today?? I am annoyed with mine every day
Can you give us some tips how to replace the matrix rad?
