Cooling fan question

[bail]

I have a corolla 1997 gli which has 2 cooling fans one behind the radiator the other one located in front of radiator which runs with the compressor. Would like to ask how come it does not run consistently the one located in front? Is this normal? Does it only run if engine/radiator is hot? Every time i start he engine and aircon i noticed it does not spin immediately

It will let the engine warm up first...otherwise it will take forever to warm up. It is designed that way.

the fan in front is a push fan and is mainly used to push air flow across the condenser,
the fan behind is a pull fan and is mainly used to pull air across the radiator,

engine cool, a/c off-----------------------both fans off

engine warm, a/c off---------------------radiator fan on, condenser fan off

engine cool, a/c on-----------------------both fans run at half speed

engine warm, a/c on---------------------both fans run full speed

Ganyan talaga design nung mga fan, pag cool pa ang engine di talaga gagana ung fan sa radiator, pinaka the best kc mag warm up muna engine bago gamitin para mag fit ng maganda ung piston ring sa liner. Ung iba ginagawa naka rekta ung fan,kaya pag naka on ung ignition aandar na ung fan kahit cool pa ang engine, matagal mag warm up ung engine pag naka rekta ang fan

Good day po!

Di po ako makapag post ng new thread kaya dito na lang ako magtatanong. Yung 2014 LC Prado namin walang cold air na lumalabas sa second row pero sa 1st at 3rd row meron. Usually bumubuga siya ng cold air after 5-10 mins. Normal lang po ba ito?
