Thread: TD5 Fuel Cooler leaks.

[quote=tombraider;552605]

"And considering the total number of leaks reported on this site equals <3 I'd say its nothing to worry about..."

It happened to mine and my investigations at the time suggested that it was pretty common.

I have also traced a water leak to my fuel cooler and have removed it for inspection. On disassembly there are 2 'o' rings, one at either end. These are rather large and I am now hoping to source some.

Has anyone done this or know what 'O' rings to get?

Yep my fuel cooler was leaking for about 12 months before I got" Davis performance "to put on another reco one. For only $ 110. fitted I thought it was a bargain.
I took a while to get it fixed because it only leaked when we had a frost and it was only a cup full at a time. So I kept an eye on the coolant levels and had it replaced when I did the major service and changed all fluids.
By this time it leaked every night, but not under pressure, and it was loosing a lot more fluid each time.
There were other issues with the motor at the same time but thats another story and not related.

I just got some BS225 Viton O-Rings as suggested earlier in the thread. I haven't fitted them yet, the night's arn't so cool at the moment and it has stopped leaking. I will be changing all coolant hases and coolant soon, so will do them then.

Is any one has a pic of the TD5 fuel cooler?
Thanks,
Amit

(Nótese que en la parte trasera tiene como una especie de válvula de retención con un muelle o quizás sea un termostato, en el pezón marca 86, ¿pudieran ser grados?

Las piezas utilizadas en esta reparación son dos juntas toricas de 49mm de diametro interior por 54 de diametro exterior más dos abrazaderas de 7 mm de ancho.

Pues esto es todo amigos.

Thanks for the photos, I'll be chasing the O rings in a few days and repairing the fuel cooler ASAP.

With the cold nights (well cold for QLD) starting, I noticed some coolant under my front diff this morning. Followed it back and its the same problem as encountered by others in this thread, a leaking fuel cooler. Not as uncommon as first suggested it seems.

Will try the o-rings first and see if that fixes the problem and take it from there. With luck the o-rings will solve the problem.
