Thread: wading plug size?

If it's a Tdi, it's 1/4" BSP

Sorry all. It's a td5 2005.
Sounds like it's the same size.
Thanks

TD5 dont need a wading plug...

Heck mine swam all its life and never had one fitted...

I haven't had to fit them in my TDI yet and can understand the timing belt one...don't want to shorten its life. But the other one? Fly wheel or wherever it is... Is that really necessary? Always thought I wouldn't bother with that one.

Muddy water in the throw out bearing .
It will shorten its life very quickly , I found this out the hard way .

On my 300Tdi Defender, I have just applied the same principle as used by Land Rover on its gearbox, transfer box and diff breathers. ie They have plastic hoses attached and the open ends are located well above any likely planned wading depth. Bought two brass fittings to screw into 1/4" BSP holes where wading plugs go and to take 3/8" hose pushed onto them. To minimise possibility of hose and fitting catching on anything passing under vehicle, they are right angle type with the middle part like a cube which makes them easy to screw in. Have used clear 3/8" plastic tube. While inspecting under vehicle, dirt can be wiped off the outside next to the fittings to check that there is no oil coming out of the clutch or timing belt housings.

The wading plug on a td5 is a 15mm thread for the record .
$3 bucks from local hardware store.
Thanks all

Did the same thing to the gearbox plug but mainly to stop oil dripping on the driveway and monitor how much oil is coming through the seals.
