Overheating engine radiator fan

Volkswagen Golf 1996 Golf mk3 1.6 141900 miles

I drive golf mk3 1.6L '96 model I would drive short distances and my car radiator fan stays on longer than expected I return from my short trip park my car and radiator fan would stay running for long period not normal... Coolant level in reservoir bottle hardly seems to drop temp gauge sometimes leans slightly over 90 degree. Could there be blockage somewhere in cooling system? Should I flush... Another issue I recently had hot water pipe replaced but now seem to have Hot air blowing into cabin even when heater switch is in off position...i tried using car heater but it doesn't seems to blow hot air into cabin cool air only

If the radiator fan is staying on longer than expected and the engine is overheating, it could be a problem with the cooling system or a malfunctioning component.
Here are a few things you can try:

Check the radiator. A radiator that is clogged or damaged can cause the engine to overheat. You can check the radiator by looking for any visible damage or debris and by checking the coolant level.
Check the thermostat. The thermostat is responsible for regulating the flow of coolant to the engine. If the thermostat is stuck open or closed, it can cause the engine to overheat.
Check the radiator fan. If the radiator fan is not functioning properly, it can cause the engine to overheat. You can check the radiator fan by turning the ignition on and observing the fan to see if it is spinning.
Check the water pump. The water pump is responsible for circulating the coolant through the engine. If the water pump is not functioning properly, it can cause the engine to overheat.
As for the issue with the heating system, if hot air is blowing into the cabin even when the heater switch is in the off position, it could be a problem with the heating system or a malfunctioning component.
Check the heater control valve. The heater control valve is responsible for regulating the flow of hot coolant to the heater core. If the heater control valve is stuck open or closed, it can cause hot air to be blown into the cabin even when the heater switch is off.
Check the heater core. The heater core is responsible for heating the air that is blown into the cabin. If the heater core is clogged or damaged, it can cause hot air to be blown into the cabin even when the heater switch is off.
Check the blower motor. The blower motor is responsible for blowing air into the cabin. If the blower motor is not functioning properly, it can cause hot air to be blown into the cabin even when the heater switch is off.
If you are unable to identify the source of the problem or if the issue persists after checking these components, I recommend having a mechanic diagnose and repair the issue to ensure that the problem is properly addressed and the vehicle is safe to drive.

Hi last week as i was driving my VW mk4 out of the carpot i noticed a sign on the dashboard indicating that there was no coolant. I opened the bonet only to find the coolant pot in a mess! it was full of oil thick milky substance!! it had NEVER shown a sign of heating. I have not used it since then. What could be the problem and what is the likely solution?

Hi I got a mechanic from AGBA MOTORS NAIROBI who fixed the problem. He replaced the oil mixer which was worn out! Then flashed all the oil and replaced with new engine oil and a new oil filter. Now good to go!

1) Was ECU reset / programmed for new battery as this changes the charging method? 2) Check / clean ground points & main positive & negative cables for corrosion & loose connections.

Heat problem

Volkswagen Golf 2010 2.0 TDI 280000 miles

VW Golf Mk6 2.0 TDI: the heater blows hot air until the engine reaches 90°C, then it completely stops. When it reaches 90°C, there is a clicking/ticking noise and after that no heat at all. What could be the cause?
