Coolant reservoir rules
speedyxjs - 23/9/09 at 11:08 AM

Just want to check before i take it further, am i right in thinking the coolant reservoir has to be transparent and hold at least one litre?

unless its been changed since IVA came in, no. mines aluminium and holds about 500ml

Cool, that means i will be able to use my power steering reservoir as it is black and about 300ml but the outlets are the right size

You’re just making up new rules now

There are no requirements for coolant reservoirs - it's not safety or environment related.

The washer bottle must be at least 1 litre but there's no requirement about being transparent.

No rules, but remember water expands about 4% by volume from 20 to 100C...

So for 300ml expansion space the most coolant would be 300ml*(1/1.04)= 7.5 ltrs..

And that's without any air in the system..

My CVH has around 9ltrs; I guess the Jag engine must be similar? You are going to need a 1ltr or more to get it to work unless you have a separate expansion bottle on the pressure cap outlet..
