OK.. am I trippin? 1st vs 2nd gen question
Why do the first gen LS's have two radiator fans and the 2nd gens only have one?
Or are they all supposed to have two fans? The 1999 I picked up today has one fan. :chicken: /I peeped the owners manual it says "cooling fan" I.E. one, but wanted other's input as well. Thank you. |
That is correct, gen 1s have 2 fans, your 99 only has 1.
|
Don't the 2nd gens technically have two?
The main cooling fan operated by a hydraulic fan clutch, and then an auxillary electric cooling fan that's mostly for the air conditioning off to the side? While the first gen had two electric fans in addition to the main cooling can for a total of 3. |
It depends on the market area.
My '90 and '94 had only one electric fan, and my '98 has none! |

On the LHD gen 2 LS400 with one electric fan, the number of fan vanes even varied depending on market, e.g. more fan vanes for the Middle East. |

The reason was given in post #4. It depended on market, i.e. the range of climates that might be encountered.
