HY 72 engine and Green coolant

[H Pickup Lover]

Hi,

Please excuse me if this has been answered in the past.

We have a HP 1966 with H72 engine. It has blue coolant in it. I belive it was shipped with this in the radiator from France.

My question is can we use "green" coolant which here in the US is used in older cars including our DS.

Wondering if this green coolant is Okay?

Here's info from Amazon. Original Green Low Silicate Concentrate Antifreeze

Many Thanks,

Hi Kat & Garric,

You can use any type of coolant, as long as you flush the system before you change the colour.

Some mixtures are allowed, but I would not take te risk as you don't know the specifications of your current coolant.
