There is no temperature indicator and the car overheats. This caused the hose to the coolant to leak. I had the housing unit replaced but then the car still ran hot. I had the get the whole thermostat replaced. No forum could assist with the replacement of the 2019 as if this year model doesn’t exist and the part needed doesn’t fit properly making my car inoperable.
