Who makes a timing cover / water pump bolt kit for 94-95 GT's???

Dan95-5.0 · Feb 5, 2006

thanks for the sizes

do you have the sizes for the timing cover too?

95cobraguy · Feb 5, 2006

most of those bolts pass through the timing cover and thread into the block. when the water pump is off of the timing cover there is only 4 bolts holding it to the block.

Dude I would just take your bolts to a specialty hardware store that only deals with nuts and bolts and ask for what you want, they will match perfectly and you will have more options as in stainless, whatever you want to do. plus it will more then likely be cheaper in price also

Rockin_rickid you ask ARP if they could keep those measurments you gave them and make a kit for sn95's?

thats what i'm gonna do but the car is in storage right now. not going to take the motor apart till spring.

after i get the measurement for the timing cover, waterpump, valvecovers, lower intake, thermostat housing, i'm off to the bolt store to pick some up. i want to try and go today

thats a real nice kit but the allen head design scares me as far as rounding off. i have the arp lower intake, header, and t-stat housing bolts, and all the others (oil pan, valve covers, w/p and timing cover, accessories and various others) i pieced together from home depot and www.boltdepot.com

R.J. · Feb 7, 2006

canadian94gt: Do all the bolts in that kit fit as advertised? i.e. timing cover and water pump.

DarkProphet · Feb 7, 2006

If you go to their store, they offer them i hex head as well.

i was going to same the same thing. i would be afraid of rounding the bolts overtime

I have a little bit of experience with S/S fasteners. (For years, I polished them and sold them for 50's streetrod trucks). Anyway, a few things you should be aware of if you use them on your engine (or any other high strength application). Most of the S/S bolts you will find for sale retail are not very strong. They are typically about a Grade 3 if you are lucky. Most automotive grade fasteners are at least grade 5, most are grade 8. Always use anti-sieze designed for nickel based metals. The S/S threads will gall very easily. Don't use them where failure is going to be a tragedy, because they will frequently stretch and/or break. Valve cover bolts is about all I use S/S for on the engine.

So that E-bay kit probably wouldn't be a good choice since they're not Grade 8. Shoot, that looked like a pretty sweet deal.

Shoot me an auction number and I'll interrogate the poor guy if you'd like.
As a rule, I have found my S/S vendors unwilling to provide any guarantee of tensile strength in any bolt that wasn't outrageously expensive. Most of my opinions are based on experience out in the "garage lab". Actually putting the torque on the fasteners and measuring stretch or failure.

And BTW, I'm not saying you necessarily need grade 8 bolts for a timing cover. Grade 5 will suffice for engine covers. Most S/S hardware is about grade 3. The crappy hardware you get with your Wal-Mart stereo cabinet is usually about grade 2. Just to give you an idea.

I called ARP and told them that the kit I bought didn't fit even though it said it would. He offered to swap the ones I didn't need and send me ones I did for free.

I got:

2) 3AG1.250-5CL
2) 3AG2.000-5CL
2) 3AG2.250-5CL
1) 3AG2.500-5CL
4) 3AG3.250-5CL
2) 3AG4.250-5CL

These are all 12 point, black oxide 5/16-18 bolts. The x.xxx after the initial "3AG" in the part number is the underhead length.

If you want ARP, you can probably call them and order the specific ones you need (plus washers....). The cost of these bolts was 13.23 (w/o washers or tax or shipping as of mar 2004), although they were free as they were swapping for my others.... I think that the 'kit' of ARP bolts was more than that, meaning it would have been cheaper just to call ARP direct and order from them... maybe...

"These are all 12 point, black oxide 5/16-18 bolts."

Rick's way is a MUCH better plan. Or any plated high strength fastener. Those will keep proper torque, and come back out years later without an issue. I'd still throw a little neversieze on them due to the steel on aluminum contact.

Dan95-5.0 · Feb 8, 2006

perfect. thanks for the sizes.

will ARP sell there bolt kit and replace the timing cover bolts with the ones i need if i order direct from them?

R.J. · Feb 8, 2006

rockin_rick: Did you mention to them that these bolts make up a kit for SN95 Mustangs water pump/timing cover and they should sell them as a kit?

They did for me, perhaps I got the right guy on the right day

I'd just call them up and tell them that you wanted a kit for your waterpump/front cover, and they don't have one [that fits] and ask them if they'd sell you the individual bolts needed. In addition, I think that it may be cheaper to buy individually direct from them (but not sure). That's the impression that I remember getting back then...

I told them that I wanted a kit and for my year car, the ones that they said would fit didn't fit, and that they needed seperate kits. I didn't specifically say that they should sell them as a kit, I figured that if they were interested, they would have taken note.

heres a list i made with pretty much all the bolt sizes i'm gonna get tommorow.

Water pump/timing cover
the thread size is 5/16 -18. here are the measurements:
(2) 1 1/4 in. long
(2) 2.000 in. long
(2) 2.1/4 in. long
(1) 2.1/2 in. long
(4) 3.1/4 in. long
(2) 4.1/4 in. long

Valve Cover
the thread size is 1/4 - 20 thread,
(12) 1 in. long

Thermostat housing
the thread size is 5/16-18 thread,
(1) 7/8 in. long
(1) 3/8 in. long

Intake bolts
the thread size is 5/16-18 thread,
(12) 2 in. long

the valve cover bolts are a little bit longer then your regular sn95 because i'm using fox valve covers.

the only one i'm missing is the distributor hold down bolt and oil pan bolts. dont really care for the oil pan bolts. cant see them.

if you see something wrong let me know.

rockin_rick · Feb 10, 2006

I doubt that it would matter, but my measurements were taking into account the washer under the bolt heads. I doubt that the threads were that close to bottoming out, but cannot say for certain. Perhaps you should check or use washers under them, as ARP does.

I'd get studs for the valve covers, it will make putting them on a lot easier... I use an ARP valve cover stud kit - intended for chevy apps, IIRC.
