Pattern expansion tanks... any good?

Recommended Posts

as the old adage goes

 

"buy cheap and pay dear"

 

remember the amount of pressure and heat it will be under..............the last thing I would do is buy a cheaper patern part expansion tank

agreed, stop being a tight arse and buy a vag one, otherwise 20 pounds will seem rather insignificant when you get a garage bill of 1k so fix/rebuild your engine!

never heard of any problems with the GSF ones, I wouldn't pay for a VAG one either, unless it was second hand.

They're not under that much heat and pressure anyway, I'd be more worried about old rubber coolant hoses than a pattern expansion tank TBH.

Not everything that's non VAG is rubbish, that seems to be a recently aquired myth with VW's.

I've run on loads of pattern parts since I bought my first dub in 1989 and the only problem I've ever really had was a slightly weak beam pattern on a mexican made pattern mk1 headlight.

i would buy a 2nd hand one (i work in a salvage yard) but the only reason we are changing is because it is filthy.

 

as for the hoses, they have nearly all been changed over the last year.. lol

 

i may get one and see what the quality is like

Err yeah, a lot of people have had issues with the pattern ones leaking and also the senders tend to only last a year or so...

 

What car is it - my G60 one from VAG was £16+ vat but that was a few years ago now... I did buy a MK4 one recently tho and it was £10, sender plug different to Corrado tho...

Avoid the GSF ones. My GSF one was so badly patterned that I couldn't even connect the damn level sensor plug to the side of the bottle. It just flat out would not go on, regardless of a little strategic filing of the connector on the bottle. Complete pants - if they can't even get THAT bit right....

 

For cleaning the old one out, someone suggested a bit of laundry / washing powder and hot water... seal it in and shake it about a bit and let it work the grime out but it seems to be the plastic that discolours over time rather than it just getting dirty.
