Hello,

Just lately my fan has been making a really loud noise just after starting my car. It sounds almost like an industrial fan that's blowing really hard. The noise gose away afeter a few minutes. What could this mean?

 

Your SAP is bad or you have a large crack in one of the hoses leading from it.

 

what is SAP?

 

Your Engine Coolant Temp sensor may be out. It could cause the fan to run at inappropriate times.
