Head bolt locations - need some help.

[kitra]

I'm trying to assemble the 5.0 liter V8 in a 1999 Mercury Mountaineer. Some of the head-bolts have a stud protruding from them. The book shows only 1 side, and show 2 with a stud sticking up. The head-bolt kits from Ford only came with a total of 2 head bolts with the stud sticking up. Does anyone know which head bolts have the stud sticking out the top of them and their locations. They are only the lower head bolts as the uppers are under the valve covers.

I would be great is someone knows as these TTY headbolts are good for one tightening so I don't want to have to remove them once they are torqued.

Thanks millions!

They go in the cylinder head on the left side...

The location for the studded bolts is the middle hole and the rear hole on the left head...I am trying to pull a picture from my service manual to show this location...

Text from the manual... 3. Note:
Only the LH cylinder head is equipped with spark plug wire brackets.

Install the cylinder head on the head gasket and loosely install the new bolts.

And the torque specs are as follows...

µ 4. Tighten the bolts in three steps.

l Step 1: Tighten to 34-47 Nm (25-35 lb/ft).

l Step 2: Tighten to 61-75 Nm (45-55 lb/ft).

l Step 3: Tighten an additional 85-90 degrees.

You've been an amazing helpful resource, Ranger7ltr. Getting is close to fire point. Heads on, exhaust manifolds done, lower intake, valve covers, now working on wiring harnesses, and upper intake, EGR and all that stuff, no coil pack installed yet or spark plugs. So with any luck, it will be running tomorrow. Thanks again!

Not a problem...

Hope your project goes well...Get her running and see if the heads are working properly and the engine is working well...

BTW, the last time I had to change heads was thanks to a leaky coolant bypass line that blew out...This would be a great time to replace the hoses throughout your truck too... Just an FYI...

Good luck!!!!
