1996 mercury Grand Marquis exhaust bolts

Showing 7 out of 7 Posts
Question From mercuryman on 1996 mercury Grand Marquis exhaust bolts

I have a 1996 Mercury Grand Marquis, and the exhaust to manifold pair of stud bolts are stripped. I want to have the new pair when I get off the old bolts.
How can I find the size?
I went to 4 auto part stores, and 3 hardware stores, and they only have 12 mm which is too big.

I need to know if it is a 10mm or 11, and the entire exact size would be better. Does anyone know the correct size, and who has them in stock.
Rock auto, and home depot DO NOT.

Response From Discretesignals

You mean down on the manifold exhaust flange? These studs?

Those are the ones I found, but are 12mm for the manifold to engine. I need just the pair to connect the catalylic converter to the manifold. They look exactly like that, but are smaller size. No one has them in the auto store, but Dorman has them online. I need to find out if they are a 10mm or 11mm, but the place is closed till Monday morning. My guess is a 10mm since most of the bolts on my mercury are a 10 mm

Response From Discretesignals

These are the one that screw into the cylinder heads for the exhaust manifold.

I need the 2 that are on the front end of the catalylic converter. It connects near the starter, and connects to the end of the manifold. They are the 2 stud bolts that connect the front of the catalylic conv. to the car.

Response From Discretesignals

The two that bolt up the front pipe to the exhaust manifold outlet aren't bolts. They are studs and nuts. The stud screws into the exhaust manifold outlet.

Your saying 12mm studs are too big for the exhaust manifold outlet?

You could try the dealer if you can't find the right one. Call out number is N806227-S100 for the stud and N806228-S100 for the nut. Don't know if they are still available though.

Yes ,its the manifold outlet, and they are studs, and nuts. Nobody around me has them, but one dealer online. Thanks for the fast reply. I hope to get them early next week to finish the job.

Question From shorad1 on 89 mercury topaz jerking

My 89 mercury topaz jerks and is slow on the road as i drive. it feels like it is a vacumm prob but i have no idea.

Response From steve01832 Top Rated Answer

You may want to start by doing an exhaust backpressure test. If the converter is clogged the vehicle will not accelerate. Also check your EGR to see if it's hanging open. If these aren't the culprit, post again with more info about the car.

Response From Tom Greenleaf

If the car idles well it's probably not a vacuum leak but certainly worth checking out all vacuum connections and the hosing.

While in there rule out any leaks in air cleaner and wiring connections, You will get a check engine light or code that may help if this continues, T

93 Mercury Tracer loses power

Question From grayszy on 93 Mercury Tracer loses power

1.9 Mercury Tracer started losing power a few weeks back, especially goiing up hills and during acceleration. No engine light. Changed the fuel filter, air filter, plugs and wires. Corrected the problem briefly. Problem started again and only way I can start out is in low gear. Changed TPS. No improvement. Runs fine until it warms up. Any Suggestions?

Response From Tom Greenleaf Top Rated Answer

Exhaust restriction? Fuel pressure problem? Worth checking,

Question From bassmasterskip on Mercury Mountanieer

1997 Mercury Mountaineer 5.o 4wd When taking off real fast the car makes a thumping noise in front end If you take off slow no noise One mechanis says transfer case another says exhaust bracket. Transfer diagnosis says chain is slipping on gears Is this acurate a chain and gears system.

Response From Tom Greenleaf Top Rated Answer

I'm not the best at 4X4 but it's not chain driven - I'm pretty dang sure of that. Check out the smaller stuff first like u-joints, slip joints and and rubber mounts,

Broken Exhaust Bolt- Mercury Mystique/Ford Contour

Showing 2 out of 3 Posts | Show 1 Hidden Posts
Question From blt on Broken Exhaust Bolt- Mercury Mystique/Ford Contour

Hello,
One of the 2 exhaust bolts broke joining the flat flanges between the flex joint and pipe leading to the muffler.
This cased the gasket to separate and decay eventually making my car sound more like a motorcycle.
These 2 rusted in bolts have round heads and protrude about 1/8 inch from the flange.
Are these bolts or pressed in studs? How do I remove these to replace with new bolts and gasket without disturbing/damaging the rest of the system?
Thankyou

Response From Tom Greenleaf Top Rated Answer

There are all kinds of funky tools for this but best is usually oxy-acet torch which you probably don't have. If there's plenty of room there are permanant "C" clamps with points and things that can go right over the broken bolt. If this is with spring there that won't work. The muffler shops do this all the time and could save you a weekend to get out of this,

Response From blt

Thanks Tom for your reply,

After using a rust buster and hammering on a punch, I took it to the local (Meineke shop) and the guy quoted me $65-85 and that included using my new gasket! Forget that. Went to a local general repair shop and he did it for $20. A few bursts with a small air chisel with a hammer head and it popped out. The nut on the other bolt came off with the impact wrench and surprisingly did not snap the bolt, after ten years of rusting. No heat needed! So it's good to go...
