I'm installing a Maradyne Mesa Heater into my 2014 Polaris Crew 570. I've read every post on the internet about this, but have yet to get a straight answer. So I decided to start a thread specifically for the options on the 570. There is a 1/2 bypass hose on the 570 engine that will provide pre thermostat water. Has anyone installed a heater tapping this bypass hose? What is the best way to tap the coolant lines for a heater? Thermostat adapter needed or not?
