Fan Belts

[LIRacer]

I have a 1970 LT-1. I was a californis car so I believe it had A.I.R.. The fan belt pulley plate on the water pump only has two groves with one belt going for the Crank / water pump, and the other for the crank, water pump and alternator.


questions:
1. Did all LT-1 s come with AIR
2.How do you adjust the tension on a belt going only between the water pump and crank pulleys?

1. All LT-1s had AIR irrespective of original delivery destination.
2. The belt is not adjustable. If it's slipping it needs to be replaced.

What he said.

Make sure the replacement belt for the crank/water pump is not too tight. IT will take out the water pump bearings fairly fast if it is. And too loose it's wasted space. I have the number for a BB but not the SB crank to water pump belt.
