AYEOH5.0

been on google, can only find for a 305 chevy 5.0 noone seems to post water pump specs when they post a big chart of torque values. anyone know?

decently tight with a 3/8 ratchet is fine, although I'm sure the proper spec is somewhere in the 20-30ft lb range. Not too much, but not too loose.

I must have done over a thousand waterpumps by now, never torqued a single one, never had a leak caused by improper torquing.

okay thank you. and if you could possibly answer another q for me? i had to buy a pulley spacer with my new balancer and it says it included an adapter ring that goes between the damper and the spacer, but i didnt get one with it. could i just install the spacer straight up?

I'm not sure. I've never had to install one.

Does anyone know the torque spec for a 3.7 water pump replacement - it would be great to get it for the thermostat and the water pump if possible. I can't find it anywhere.

The 4.6 and 5.0 water pumps are 177 in-lbs, in sequence for step 1, then +60 degree
turn in sequence for step 2.

Call an auto parts store like Advanced or O'Reillys and they may be able to look it up for you.

Do you have a picture or at least the part number of the balancer you're using thats requiring a spacer & what make,model & year car are you working on?? Ive seen some balancers with a spacer that required a snap ring,some that required spacers and some that didn't require anything.When you say adapter ring,its probably referring to a snap ring. If so,the snap ring is used so that the pulley will have something to bottom out on.There should be 1-2 grooves in the spacer where the snap ring fits into.You choose which groove to use based on where the pulley needs to sit for proper alignment with the other pullies.If you set the pulley on the spacer,does it bottom out against the spacer correctly or does it slide completely over it and hit the balancer?? If it hits the balancer, the snap ring is needed.

***ATTENTION***
The torque values listed below are strictly for a 86-95 5.0 Mustang.They are NOT for a late model 3.7ltr.....
If these values are used on a 3.7ltr,severe damage will occur to the pump,bolts,tstat housing,etc,so please
DONT use these for the 3.7 ​

My Chiltons manual shows 12-18 ftlbs also for the 86-95 water pump bolt torque.The wp pulley to hub bolt torque is shown as 36-47 ftlbs.Specs are for a 86-93 5.0 Mustang.
