300Tdi coolant reservoirs

[wally]

I recently replaced the coolant reservoir on my 300Tdi for the second time. I hadn't had to top up the coolant but I did notice it just starting to weep along the join. I only got four years life out of the old one which is not too inspiring. You would think that somebody somewhere would have come up with an aftermarket one that actually lasts.

There is someone on Ebay selling stainless steel or aluminium ones for around $300- a lot of money i know but would last 1000 years.

The black plastic ones have a bad reputation. By all accounts the white plastic replacements have overcome the problem of seam failure.

The white plastic ones are better, I have never had to replace one of them yet.

Some I have fitted quite a few years and KM's ago too.

our white plastic replacement tanks are ok (so far that is) .... fingers crossed

at least the weep on the black tanks gave us a little warning....

Check your cap is venting, I have come across 2 split tanks on the same Disco that were caused by the cap nopt venting under pressure.

30PSI is the max I think from memory.

15 psi.
I've had problems with aftermarket ones not sealing.
The genuine caps (German) are cheap from places like the company in Sydney that cannot be named. Pt # NTC7161 (just happened to have the invoice sitting here )

Haven't had a problem yet from the genuine white tank I fitted a few years back either.

240 k,s and my black plastic one is still going strong
While your changing you black plastic tank because it might split change the head gasket cause that might blow and everything else on the car that might blow or fail
