Fan Shroud

[kselvi]

I have a 75 Blazer with a 350. I need a fan shroud. I cannot found that old of parts at local salvage yards. I have tried a couple of other GMC shrouds, but the bolt patterns and sizes do not match.

What model years can work on my Blazer?

it depends on if you have the heavy duty cooling or not. The shrouds will work from 73-80, but are different between the HD cooling and non HD cooling. The HD setup has a bracket that bolts to the top of the radiator support and goes straight back, the non HD cooling has a bracket that bolts to the backside of the rad support, and makes a 90 degree angle to hold the radiator and shroud.

Like johnboy said. My two cents are this...if you try and convert to a HD cooling sytem and your core support was not a HD cooling unit you will need to add 4 nutzerts into the top of the core support to bolt in the top plate that holds the radiator. If you get a good gm parts guy you can order them from gm....but...you will need an air operated installer as they are thick and will break a hand setter...been there done that. Most dealerships for semi's will have such a tool as the cabs and sleepers are all put together with rivets that use crimp collars...and for the life of me this morning i can't get the correct name out of my pee brain....wait a minute...they are called huck bolts.

Check with LMCtruck.com. I recently got a one piece Big Block shroud from them for $50.00. I couldn't find one until trying them.
