wow so no one has a stock factory 82 85 LG4 anymore ?

damn

that sucks

help ?

thanks

 

my '82 LG4 fan and water pump are sitting on the ground. I can give you any measurements you need, let me know.
I'm about to start a new thread about replacing it...

 

how large is fan across

is the radiator stock ?
if so then is it alum or copper

how wide from tank seam to tank seam

does radiator sit in the shroud or in front of it

thanks

 

17"

dunno. easy way to tell?

Not sure which measurement you want here.
pic
arrow to arrow is 26 3/8" +/- 1/16"
*edit* there's a broom handle in the way, that's what the left red arrow points to, I actually measured all the way to the end of the fins, just like the right side.

in shroud


That about cover it?

 

yeh that solves a few mysteris for me so far

i appreciate

also if anyone has pic of an original early third gen LG4 fan then please lemme see

also do they use one of those aluminum spacers ? or is it clutch driven all the third gen years ?

thanks again

 

From my '83 service manual it states that the majority on non-A/C vehicles have a 4 blade fan.Then some models have a 5 blade variable pitch fan.The next paragrah states that some A/C equipped vehicles have a clutch fan.Now that's about as clear as mud LOL.To complicate things more,cars with heavy duty cooling will have a 7 blade clutch fan(mine is like this and the fan is 18" across).The flex fan vehicles would have to use some type of spacer to place the fan properly in the shroud.The fan is positioned inside the shroud typically with the blades width centered(half inside and half outside).I hope this helps more than it confuses.
