Anti Freeze

[Number 6]

Rover 25 with a K series 1.4 engine.

Any one know which anti freeze to use ????
OATS or the old Blue Stuff.

Also if it already has the Blue stuff in would it be OK to give it a good flush and put OATS in ??

Your thoughts gentlemen please

I use a 5 year pink/red. Other colours you need to change every 2 years.

Well I use blue in my 214 changed annually, and that only has managed 380,000 miles on the same head gasket

Stick with blue, you know it makes sense

The difference between the two colours is that Pink / Red antifreeze contains a different type of corrosion inhibitor that has a much longer life than silicates, phosphates and borates.
Over time corrosion inhibitors are depleted and the corrosion protection is lost, therefore green / blue antifreeze should be changed every two years.

Aluminium is especially vulnerable to corrosion and many vehicles have heads, radiators and other aluminium components in the cooling system. If the coolant in an engine cooling system is changed before corrosion inhibitors reach dangerously low levels, corrosion damage is prevented.

I have seen many cases where the oat antifreeze has perished elastomers and even the nylons used in the plastic elbows!

In my old 25 1.6......which is now my dads..........I always use the OAT coolant.

I read a while ago that its kinder on the gaskets......or something.

Anyhooo......used it for the last 4 years and no ill effects

Oh Dear,annually???............The wife has had the car over 6 years and we have never changed it nor have we ever had to add any coolant during that time.Its done 90,000 miles and still on the original HG (runs away looking for a piece of wood).

Better go get some Blue stuff
