Their were 3 fan motors used in the 94-96 cars. 100 watt,150 watt and 240 watt. The 100 and 150 used the same mount,the 150 was just a little deeper.100 and 150= completely interchangeable and put on MANY cars. The 240 watt is a different story. It uses a different mount and its only available for the driver side. The 240 watt cools VERY well, however continued use WILL melt the weak stock relays and any sockets their put in! The startup current is just to much. It was mostly used as the secondary to the mechanical on towing versions. It does have a few other applications as well! The fan itself is interchangeable with all 3. The V92 tow pack always includes V08 cooling, which always includes the mech fan [which incurs a 10 peak horse penalty].
Does it also include an extra trans cooler?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.Does RPO V08 also include a heavy duty radiator as well?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.)Is there a difference between base cooling and extra-capacity cooling?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.There are two optional cooling system upgrades for LT1 B/D-cars, called V03 (Extra Capacity Cooling), and V08 (Heavy Duty Cooling). Performance models such as the WX3 (Impala SS) and 9C1 (Police) cars automatically get the upgraded V03 (Extra Capacity Cooling) system. V03 includes a larger radiator, an increased capacity A/C condenser, and an upgraded secondary electric fan. V03 is also optional on most B/D-car models.
Note that the '94 V03 (Extra Capacity Cooling) option uses a 150-watt primary (RH) fan, and an upgraded 240-watt secondary (LH) fan. In '95-'96 the V03 package was revised and no longer included an upgraded 240-watt secondary fan. Instead the standard 100-watt secondary fan was used, which is the same as the base cooling system.
PM538 for the driver side and PM540 passenger side on SS cooling package. The driver's side fan on my car has part number 22137068 and the PM9040 is the direct replacement.( '95 Caprice wagon)
The primary fan is the one on the passenger side. It comes on when the A/C is on or if the A/C is off and the temp gets to 228 degrees. The other one is the secondary fan and it comes on when the temp gets to 232 degrees.
