Bought this lovely used car 6 months ago and I love her! Cools down fast in the summer. Winter heating however, is not doing so well. My old car (1996 Mazda Protégé) heated up in the coldest weather within a mile. Miss Prius however barely gets there in 3 miles, before she gets lukewarm. Is there a problem? Or do I just live with it and wear warmer clothing? Thankyou
You may wish to have the thermostat tested or replaced. amazon.com/Stant-14108-Thermostat-Degrees-Fahrenheit/dp/B000C809F6 $20 with the seal. You may wish to consider Grill blocking, with pipe insulation. amazon.com/M-D-Building-Products-50150-Insulation/dp/B011D1381C $42 for more than enough. Grill blocking is safest if you have a way of measuring the coolant temp. I use a Scanguage 2, but their are cheaper strategies.
