Why does the Volkswagen Sagitar's heater warm up slowly?

[VonLiam]

Reasons why the Volkswagen Sagitar's heater warms up slowly: 1. The thermostat is constantly open or opens too early, causing the cooling system to enter the large circulation prematurely. The cold air cools the antifreeze, resulting in insufficient heating; 2. The water pump impeller is damaged or slipping, leading to insufficient flow through the heater core, preventing heat from rising; 3. Air pockets in the engine cooling system cause poor circulation, resulting in high coolant temperature but insufficient heating. In terms of body dimensions, the Sagitar measures 4753 mm in length, 1800 mm in width, and 1462 mm in height, with a wheelbase of 2731 mm. Regarding the suspension, the Sagitar features a MacPherson strut front suspension and a multi-link rear suspension.
