One more question, anyone know if it should be peeing out water as soon as the engine starts on garden hose or does the thermostat need to open first. It was fine but after sitting for about 2 months, I hooked up a garden hose on a pretty chilly day recently and it ran good but wasn't peeling out water. I shut it down. I'm thinking I may need a water pump. It's a 2018 purchased used so no real history or maintenance records with it. Thank you
