Discussion
Just curious as to which number pressurised water expansion cap everyone is using just done a test and my car blows water out off xpansion tank at 102 degrees my car has a number 13 cap wondering iff spring or seal failing ? Inpu would be useful . Also is anyone using Evans waterless coolant in there ultima yet ?

Hi Paul,Ours goes at about 110, and did have our old cap give up. It's fairly straightforward to get a new one as its a standard part. The guys on Layerthorpe had one for ours.
I am running Evans Waterless Coolant although car is not on the road yet, have had no issues so far but engine hasn't been pushed but has been up to temperature in the garage on hot days without issue. Good points so far no issues with removing header cap when hot, bad points are that it feels strange when it leaks and you have to wipe it up, almost sticky, but not and is tad more expensive that water. I'm happy so far, cars running an LS3.

I have run Evans in my SBC for years. Never had anything close to a boilover, leak or any sign of corrosion. The only temperature gauge I keep an eye on is my oil temp.Abbosevolution said:

Must agree its odd to mop up so far things are looking good . Car ticks over now without boiling up and temp are a lot lower for some reason . Also seems strange how you can take the radiator cap off with no pressure just need a dry day and a traffic jam v8yes said:

I started out by removing the stat as per Evans original recommendation, however I didn't like how long it was taking to warm up. I picked up a 'Hi-Flow' stat when I was ordering some bits from Summit. Seem to remember it was a Mr Gasket one http://shop.mr-gasket.com/cooling-system/thermosta...Now warms up quicker, doesn't seem to cause a problem with cooling.
