My water pump belt broke the other day so I went out and bought a new one. Installed it and turn on the car and smoke came pouring out the engine compartment. The belt burnt off at the engine pulley. I just repalced the water pump a few months ago and I tried to turn the smog pump pulley but I couldn't budge it by hand. Should I be able to turn the smog pump by hand? I check the belt tension before turn over the engine. What do you guys think, bad smog pump?

Forgot one important peice of info my rig is an 87 FJ60 with a 2F engine.
Yes, bad smog pump.
Should 'spin' bt hand.
Does your PS leak ? PS fluid onto smog pump is a bad thing....
. . .it's the most common reason for smog pump failure on the 60's.
Do you have emissins testing ?
If not, remove pump, open'back' & remove 'vanes'. the vanes have a thicker than foil band around the edge. When a vane fails (gets disploved by PS fluid), the band jambs between the spinnig drum & pump housing and locker 'er up tight....
If you need pump, via internet you may find a source far cheaper (under $100) than a new toyota unit (hundreds of $).

You should be able to pull all the interior parts out, and you are left with a 8lb belt tensioner!
Sounds like exactly what happened to me. I got the pulley from JimC and this is a great time to consider a desmog if you live in an area you can do it.

yeah I did have a power steering leak when I bought. I fixed it awhile ago but I guess it finally caught up with me. So if I gut my smog pump for an 8lb tensioner do I still need to modify other parts of the engine? Or do I need to plug lines or modify the ERG(I think that is what it is called)?

Does anyone think that I may have broke it by putting new hoses on wrong? I had to replace all the 1" (more or less) lines on the smog pump.
And so this maybe causing the problem with my vacuum switch for the a/c compresser idle up? When I got it off the boat and started her up the a/c compressor idle up started to surge and in like 2 second intervals.

No, hooking up hoses will not kill smog pump.
Pully doesn't come off to remove 'vanes': take pup out of rig, back side 9where hoses connect) comes off. You'll see the vanes (with their arms to a centershaft & little bearings) vanes, arms little bearings : pull & trash. Look way down inside & look for thin metal 'band' that may be wedged between drum & housing.
A/C rapid cycling (on-off-on-off) is oft due to the system ;just barely' having enough freon to work; need more.
BUT if you're testing A/C and it's really cold (like inside of truck is already freezinf) then it may just be the A/C control system functioning normally....'test' on a very warm day....
The smog pump can not affect A/C (other than locking/failing pump slowing engine down, and slower engine rev's will cause A/C to kick off)

i've got one of those fancy 8 lb belt tensioners. easy fix. most difficult part was getting the long bolt that holds the pump out and back in.
My 87 also had some surging when the ac was on and it was easily adjusted for on the front of the carb with one of the adjusting screws.
