Hi,

Hopeing someone can help and advise me on whichh type of coolant the above Grand Voyager needs.

Some people say orange, others, red and one suggested green!!

Anybody know???

 

100,000 mile stuff the color does not matter its only dye
Do not use DEX cool GM based stuff the engine will gel up from it.

 

If you have an aluminium-cored coolant radiator, in UK "Comma GO-5" seems to be the one. One presumes the 'GO-5' title means you can go for 5 years. It's not cheap BTW. The same stuff was used in my S-type Jag. Use in 50-50% ratio with water.
You do well to see the antifreeze is changed, once the radiator is plugged up with corrosion, replacement is the only cure. Overheating makes the thermostat jam open too, as it is designed to. All in all, lots of dosh out of wallet.
