Getting tired of fixing my 5.3 GM

[ferniesnow]

Been to local GM dealer twice...that's where it was yesterday.

Poor technician? Or they just don't care?

I cured my Gm woes .....kijiji....!!

I had the exact same thing happen to the wife's 14 equinox at 40k, took it to gm, they cleaned the connection and put the grease in,was good for a couple months, just happened again last week. anyone know if there is a recall on this as well? thanks

It's not a recall, how many times I got to say it


The equinox I don't think has special policy, would be just power train warranty if it covers what's wrong

What was wrong with your 6.0 l??

 

[imdoo'n]

so this is a recall! a gm secret recall!

 

[imdoo'n]

this recall just for the 5.3 l?

Anyone having these issues? Check engine light comes one, followed by "service stabilitrak" and "service anti-lock brakes"....30 seconds later you get "engine power reduced" and you slow to a crawl. OK...happened the first time at 90,000km (year and a half ago)...told by an Autopro dealer in Red Deer that it needs a throttle body...900 bucks later and I'm down the road. Happened again a month ago at 135,000km. Take it to the Autopro in Sylvan who tells me there is a service bulletin from GM and to take it there as they will fix it for free...no charge. Was informed that this comes up on the Autopro software when the truck VIN and code is input and that the previous Autopro dealer should have known this. (don't go to Wrenchmaster is the moral of the story here) Took truck to Kipp Scott and they changed the TP sensor under warranty.
Anyways, lasted a month. Same issue Friday...then again today. Kipp Scott says they "cleaned connectors and added dielectric grease to harness, but if it happens again, you need a new wiring harness". Getting dinged 2 or 3 hrs labor on this one. (haven't picked it up yet, so not sure)

WTF GM? I am pi$$ed. Is it time for a Toyota Tundra? Any GM techs out there have any advice?

Don't get me wrong...I love this truck. Just spent a bunch of $$ and time making it all pretty again and put new tires on 'er....but this throttle body thing is annoying.

I know people heads are in different places but Dielectric grease was never intended for electrical wiring harnesses. It's purpose is SPARK PLUG wire connection ONLY.
Dielectric grease is a CONDUCTOR and not an insulator. Thus when used in a harness, it can actually act as a short. I have diagnosed many vehicles that code out for various reason's, some was because of contaminated connection causing a short or false signal's from dielectric grease.
I even ran into a BMW motorcycle that would miss and stumble because the owner used dielectric grease on all the connection. After it was all cleaned up, all was good. If it was good on connection's the factory would use it. Spark plug wire connection is what it is intended for, like i said, its a conductor. Use it on multi pin connector and don't be surprise if it doesn't short out to another pin causing unwanted codes and weird runability issues.

Here is the rule that can be used with dielectric grease. It is ok for use in basic 12v auto system's like head light and tail light sockets and connectors or trailer connection's. In area's that raw 12volt is being used.
It should never be used on connection related to engine management system. Where .5v variance can cause issues with the ECU and related components. The biggest problem with dielectric grease is stray voltage causing false signals.

 

[tex78]

I disagree mike, something that has low voltage reference and looks at resistance like t.p sensors, air bag coil circuits ect

Lots of new vehicles are getting connectors takes out and spices put in, because of fretting ( micro carbon arcing on connected pins that cause connections to get bad)

Dielectric grease helps seal, stop fretting, and get a better contact in connectors


Many auto manufacturers have recalls for things not working ext, where one of the steps is to ADD dielectric grease,

This is what we use, and it clearly states "non-conductive".

Thought you were looking for a truck? Not a shiny sales gal!

Looking is ok, now if he took her for a test ride there might be an issue

Ok did you go into my shop and take that from my cupboard.....been using it for years.....

Yes thats is one of the product i use regularly.
I will post a pic. of another product that i just started using about a year ago.
Or you can google it, "Original PENLUB and anti-friction, from Lubri-lab. I got a case of it and put it in the shop for the guys to use and see the results. The guys love it and it works flawlessly.

I think you mean it's a insulator not a conductor ?

If it was a conductor it would short out every connection out there instantly wouldn't it?

We use it in lots of our field connections on instrumation connections to keep rain out. I've used it on lots of trucks and even a log guys scooter that kept shorting out from water in connections!

funny thing is I have 2 Tundra's in the driveway and never had issues.... and Toyota will give me a new truck for free when I get 1 million kms on them.

Only if Toyota would smarten up with the tundra and make the crew cab with a 6-1/2' box they would sell a ton more trucks. They currently have the chassis with the double cab with the 8' box??? With kids it's nice to have that room of the crew cab but a 6-1/2' box is a must and that's just getting by.

Toyota is the only manufacture that don't one in a half ton, drives me nuts!!

As Overkill stated, it is an insulator - dielectric is actually a synonym for non-conductive. I think the only potentially valid debate around the use of dielectric grease is the fact that it does not conduct and may prevent you from getting a solid connection. However, on a healthy connector, the contacts should displace the grease enough to make a solid connection. I can't say for sure, but I believe manufacturers do use a very small coating of dielectric grease in some applications to help prevent the connectors from corroding.

Agreed, but I've seen connections where it was way overdone at assembly and it will actually hydraulic the pins right out of the connector, or enough they're only connecting intermittently.

Dielectric grease is merely a corrosion fighter, it does not increase conductivity.

Happened again. Ask me how safe this is when on the Deerfoot in the left lane and suddenly your power is limited to 0.3%. Pull over, shut key off for 2 min, re-start and drive home normally (with check engine light on). Disconnect battery for 5 min and engine light gone. I am NOT putting a fricking wiring harness in a truck with this low of km.

Wow that sucks!!
