How to replace water pump on a 1994 mustang 5.0 cobra

At this website https://big-manuals.com/products/ford-mustang-gt-cobra-1994-2004-workshop-service-repair-manual
I found so many manuals that aren't here.. Also complete, this one is not, much better language, complete manual of 800+ pages, and they also have live assistance feature
You can go ahead and try it out

There are three kinds of 302s made from 1982-2001. 5.0L HO This engine was used in 1983-1995 Mustangs, Mark VII Lincolns, and some T-birds and Cougars. All Explorer 5.0L engines are 5.0L HO engines as well. They use the 351W firing order, 1-3-7-2-6-5-4-8. Except for the 1983-84 Mustangs, all of these engines are roller cam equipped. They use a reverse rotation water pump and front cover. The 1994-5 Mustang and all Explorers use a unique front cover and water pump. 5.0L Full Size Car This engine was used in 1982-1990 Crown Victoria and Grand Marquis. They use the 289-302 firing order, 1-5-4-2-6-3-7-8. Most of these cars are not roller cam equipped, however sometime in the early 1990s they started using roller cams but retained the 302 firing order. They use a standard (clockwise) rotation water pump and front cover. 5.0L Truck (except Explorer) These engines are similar to the Full Size Car engines, except they use different intake manifolds and camshaft profiles. They also use the 289-302 firing order, 1-5-4-2-6-3-7-8. They also began using roller cams sometime in the early 1990s. They use a reverse rotation water pump and front cover.

Good Luck

Hope this helps ya.. Cobra... :-)

maybe you should put the fuel injector in the car. Hope this helps

you can get high performance rebuild kits for those t-5 trans from summit for a very reasonable price and just get it rebuilt and you can hold up to 800 horses on that t-5 after that or just pick up a new or used tranny and replace it

place the pump in a vice,you have to have a special pulley tool set,follow instructions.

relays are normally in the fuse panel on the left side of dash by knee.

It's a bad bearing in the water pump and since the its a OEM part and installed by the dealer it will be under warranty,you should take it back to the dealer where the work was done.

A bent/kinked metal fuel line could cause this. Post your findings.

i believe this part you are referring to is the intake manifold. it seems to be a big problem with the older ford mustangs. make sure before you spend the big bucks on it that it's not just the water pump gasket.
