Fans

[bigbluebus2500]

Hi, Newby here.

Just got my first Caprice. It's a 1994 Wagon with LT-1.

One question: why do some of these cars have electric cooling fans like mine, and I've seen others, same year that has a mechanical one (belt driven)?

Cars equipped with HD cooling (RPO V08) have a primary mechanical fan and secondary electric. Cars with base cooling or extra-capacity cooling (RPO V03) have dual electrics.

Thanks for the reply; one more thing: So if it has a belt driven fan and shroud...can I automatically assume it has the heavy duty cooling, like for towing? Does it also include an extra trans cooler? Does RPO V08 also include a heavy duty radiator as well?

Is there a difference between base cooling and extra-capacity cooling?

The V92 tow pack always includes V08 cooling, which always includes the mech fan [which incurs a 10 peak horse penalty].

Technically, no. All 94-96 B-cars have an integral transmission cooler close-coupled to the radiator.
All LT1 B- & D- cars also have an additional external transmission oil cooler.

Couldn't tell you. These days, the only radiator variants I can find are:
civilian radiator with integral motor oil & transmission oil coolers
9C1 radiator with integral transmission oil cooler only, no oil cooler
(On this, I could be misinformed.)

The base cooling option was a 150W primary fan, and a 100W 2ndary fan.
The V03 cooling option upgraded the 2ndary fan to 240W.
The V08 cooling option that came with the V92 tow pack upgraded the primary fan from a 150W elec fan to a 7,457W mechanical fan, and kept the 240W 2ndary.
