Q: What coolant should I use? A: All Lancers feature aluminium cylinder heads and only coolants suitable for such should be used. Look for coolants that are ethylene glycol based. Alcohol based coolants should not be used with aluminium cylinder heads. Generally, for maximum protection, use a 50/50 mixture of coolant to water. Alternatively read the directions on the coolant packaging. Change the coolant a minimum of every 2 years. Back to question page
