Please i need help. My radiator fan does not kick in on time, it works like it has a mind of it's own. I always have to turn my airconditioner on before the fan blows.

The car is overheating, its a 1999 Volvo s80. I have called a mechanic in my country Nigeria, and they said they have to relay the fan to work direct, which means they have to hotwire the fan to the battery, it wouldn't work with the thermostat anymore.

Please i want to know if this proposed method will not have any effect on water flowing into the engine when the thermostat won't be working anymore.

Please someone help me before i ask them to proceed.

 

The thermostat is not really connected to that fan. The thermostat which controls water flow is totally mechanical. So I think they are not talking about the thermostat that controls the water. The water flow will be okay.
