Ground straps at the bottom of engine ?

I saw a grounding point on the passenger side bottom of the frame and the strap was ripped from rotting. I cannot see where the other end was connected since it doesn't exist anymore.

 

Is that a ground strap going from exhaust manifold to car frame ?

 

If so is it on both sides or only passenger side.

 

Thanks

Ground straps are on both sides, and they connect from frame to exhaust manifold.

 

Both of mine have rotted through. On one side I electrical taped the ends together for now, and on the other side I just clamped the loose end between the heat shields on the manifold.

 

I'll replace both soon.

Attaches to the manifold heat shield, don't believe there is one in the same location on driver's side IIRC

Ok thanks a lot. I will take care of them next time I go under the car.

Mine rotted through as well on the passenger side. 7 years of New England winters was a pretty good run though. How anyone expected a bare copper mesh wire not to fall apart in Snow country is beyond me..

If I'm not mistaken, I thought they went from the body to the bottom of the heads, both driver and passenger side? Mine are toast- I've got new straps sitting on the shelf waiting to go in.

I think some are on head and some are on exhaust manifold. I think pass side is to manifold and drivers is to head

That makes sense..

My ground straps are in great shape, I don't know why you guys are having such problems...

 

 

 

 

 

I have a wealth of problems... The ground straps are minuscule compared to the other issues I'm having. BMB, too bad you don't live closer- I'd like to take that SMFW off your hands.

I'd like you to take it off my hands too! It's just too heavy to ship

 

Understood. Honestly, I don't want to have to pull my FW, I just want to eliminate possible reasons why my TOB would go.. again.

 

Sorry to threadjack- It's all I can think about right now.

I think they go to the heads, I remember cleaning mine and putting them on when the short block was installed. I think there is only one on the drivers side front bottom of the head.

 

Not sure I have pictures, I'll check.

 

Found these but none of the bottom one (s).

Make your own out of a piece of Monster Cable speaker wire. Find the largest gauge you can-12 if possible and just put ends on it and heat shrink them to the connectors. If you can't find 12 gauge, make a double out of 14. It's nothing but a flexible connection. I've made my own on cars for years that way and they never go bad because of the shield and heat shrink.

Or you could splurge and spend the $3 it costs at a parts store..

And have it corrode like the OE one.

Anyone have a part number handy? I noticed my pass side one has rotted off as well.

Is this an issue if one or both of the ground straps are torn? I just cut and reconnected the driver side but the other is completely gone. Will this lead to electrical interference or engine codes?

I've been told that it takes a lot of ground issues before you'll notice any electrical problems. I'd suggest taking care of it eventually, but it won't be a problem unless you have multiple other grounding issues.

Do that ^ any good piece of wire with a crimp on end will work.

 

In the bottom right side of this picture, above the inlet tube, you can see the black ground cable I made for the race car attached to the frame.

Here's a better picture.

Here are the wires I made the other day,

You can develop noise in your radio from the straps being broken.

Does anyone know if the bolts that hold the straps on are M6 or M8?

Thanks, Zack K.

6mm for the two on the bottom of the heads.

Possible electrolysis in the cooling system as well as RFI interference.
