DC Power 370xp & 5.7 350 Vortec tension pulley problem


Recommended Posts

Is there a way to tighten the free moving tension pulley on this type of setup... my alt is slipping but belt is not sqeacking...it's a old belt which is going to get changed out for a gatorback & hopefully fixes it...but I was wondering if there is a way to tighten it a little ?

Change the belt, maybe even shorter if it still slips. How much surface contact do you have at the alt, belt to pully?

there is no way to set the tension manually. how old is your tensioner? I just swapped mine out when i did my alts. its like 30 bucks for a new tensioner.

I think this is the best thing to do after talking to a few alternator shops...my tensioner is weak & I'll replace it with a new belt....thanks for info

I'm going with a Gates green belt but that website is a little confusing for me...can anyone tell me which belt I should get from them...people say the green HD belt would be best but can't find the one I need.....I need the correct name of the belt since there is a few different types so I can order or get at O'reilly's if they have it.....

So I might have to cut some ribs off so it can fit correctly on pulleys...

Which one is the better belt...Goodyear Gatorback or Gates green stripe...this is for one 370 DC Power alt so I dont think I need the all green HD Gates belt....I'm going to buy one or the other in the next 2 hours so your input is needed....I have used the Gatorback before so I know it's a good belt...me & a homie are going to install the Gates belt tensioner & a new belt @ 5pm so which one should I get
