I was wondering how I can find out what the belt and vacuum routing is on a 1991 astro van? My stickers came off from inder the hood.
Thank You.

this link appears to be broken. Does anyone have the vacuum schematics?

vacuum schematics arent always same just because same engine and model and year.

different emissions levels and packages plus if built in 48 states or in cali or in canada all have different vacuum schematics

i would go to a junkyard and try to locate another vna your year with same three letter emissions digit code on the sticker,.

or in the SPID label in glovebox in the engine cover

the vacuum lines on these are pretyt basic though

not much to them.

cruise control
egr vacuum solenoid
heater a/c vacuum line
pcv
most everything connects to or originates from an intake manifold vacuum source

i might have the sticker on the rad support of the 92 i just stripped, ill check and see

The upper image is busy and reduced. Sorry. The board won't seem to accept
images larger than 600 horizontal without clipping them.

As others have suggested, various individual vehicles will have slightly
different vacuum routings. Veh's built for cold climates, for example,
have a different PCV valve hose routing.

thanks, the second pic was what I was lookink for. The other thing I was looking for was the check valve in front of the TBI going to the "black ball" under the heatercore. Engine runs well, just want to double check my vacuum lines.
