156 1.9jtd



A real beginners question relating to my 156 1.9 JTD. Need to add some coolant but can't understand from the manual if there is a particular type I need to use, and what level of mix I need to use.

I already have some Granville coolant but want to check first...

I would stay with destilled water for "some" coolant first time.

Go by colour. Red is generally mixed with red, blue is mixed with blue. Although some dealer supplied coolants are weird colours like green and orange. In the UK, most aftermarket coolants are blue or red. If you have red, add red, if you have blue, add blue.

On concentration and mix, do what it says on the bottle. Most are good to -25 at a. 50:50 mix.

If you mix red with blue, you will get a grungy, gloopy, goo formed in the bottle.

If possible, mix the coolant with de-ionised water, or water that has been through a Brita filter to remove the lime scale forming impurities.
