i have a b18b1 with a full size dual core mishimoto radiator in my integra and im wondering if i need to have a radiator fan. when i drive it the temp stays a little below half. but when it sits there idling the temp slowly rises. its low on antifreeze right now so i dont know if that plays much of a factor but its used as a daily. with a radiator this size i just want to know if i need to go out and purchase a fan.

 

if you dont have a fan and you get stuck in traffic your engine might overheat buddy. i would invest in a fan. check out zirgo fans they're not expensive and have a good rate of cfms for their size

 

thanks

 

That is exactly what fans are for.

 

i picked up a fan like that zirgo one at autozone for $50 for a 12 inch and these fans are awesome!
