Title: Coolant Change - Part 1
Post by: x25xe on 05 August 2006, 22:05:01

Started work on my coolant change today, using Markjay's excellent write up [smiley=thumbsup.gif]

Gave the bolts securing the undertray a good soaking in plus gas along with those that fix the radiator cover and went out to buy various bits like hose clips, drain bowl and some of Sainsbury's finest mineral water!

Got back home and removed undertray and radiator cover and located the rad drain tap.  All OK so far.

Removed the expansion tank cap and then noted a series of cracks following the neck of the tank. Bu**er!

Pictures show what I mean: (first attempt at posting a pic so hope it works!)

So, went to vaux (dealer only ½ mile up the road from me) to get a price.  £39 for a tank with sensor and in stock!  Why do that have that and not a brake light switch I wonder?

Anyway, I will be fitting a new tank as, whilst I am sure that this one will be OK for a while, I like to do things properly.  Will be phoning Autovaux on Monday to fit out their price.

Still, I was going to take the bottle of and use a bottle brush to clean it up - at least I will have a nice shiny new one now I suppose!

If i am looking at the correct thing.....i think they are mould marks......i got the same on my bottle....if you run a nail over them they stand proud a bit.....and nothing to worry about.

I carnt see anything else in the pics that look like cracks.

Cheers

Thanks for your input TD!

The cracks are around the filler neck on the bottle and the are certinally cracks.  You can feel that they are cracks when running a nail across them.

I will be fitting a new bottle for peace of mind apart from anything else.  Also, the old expansion tank is somewhat dirty so a new one will save having to clean it up and display my newly replaced coolant off to best effect!
