Re: Are there any GM Techs out there?
GM has standards for heater performance, so heating up coolant quickly so the heater provides heat to the passengers is a high priority . Included in that is they don't want to shock the block and heads with cold coolant ,so the special thermostat was developed . I believe its similar to the older LT1 style thermostat .
