I ordered a 2010 GMC Terrain SLT AWD/3.0 engine from Rimrock Auto Group,Billings,MT to be built the week of 12-14-09. The dealer says an engine block heater is not available on this vehicle. GMC website does not show it as an option. These Suv's are made in Canada and come with engine block heater as stnadard equipment there. Also the Cadillac SRX has the same engine and the block heater is an available option on them for $100.00. Why can't we get it here in Northern Montana where temperature can get to -40 degrees. It is a must here! Did something get overlooked here? They say these engines start good in cold weather,even at that it is very hard on an engine to start them in extreme cold temperature without a heat source.Not every one has heated garage. Is GMC going to provide an engine heater option? Please advise me what can be done for this problem.Thank you.
