Chevrolet Tahoe Z71: I have a 2004 Tahoe. My oil pressure will

Customer Question

I have a 2004 Tahoe. My oil pressure will drop to zero at stops every so often. When I start driving again, the pressure gauge goes back up. I took it to the dealership and they replaced the sender. That didn't work. So they looked further and said the cluster was worn, which is causing the problem. Is this simply the gauge cluster on the dash or is it something else? I am being quoted $650 to have it fixed, which sounds high if it is simply the gauge on the dash.

Hello, my name is ***** ***** I'm here to help get your problem solved. The instrument cluster is common to fail so I agree with dealerships diagnosis. You can buy a cluster yourself and install for $200 or buy cluster and have shop install which will bring total to $300. The next cheapest option would be remove cluster yourself, send it in for repair, and then install yourself which would cost a total of around $80. Here are links to buy cluster or have repair service done. Let me know if you would like replacement instructions, thanks.

If you could provide replacement instructions that would be great. So the oil gauge itself can't be replaced? The entire cluster has to be replaced? If the oil cluster is bad, is there any negative effect it can have on the engine or any other components or will it just be the annoyance of having the oil gauge fluctuate and read inaccurately?

You could rebuild the cluster yourself for around $40 but I haven't done it so not sure how easy/hard it might be. The only problem with not fixing gauge is you woudlnt know if you were having a real oil pressure problem in the future. Here are replacement instructions for cluster, let me know if you have more questions. Thanks.

Thanks again for that info. Do you have any sort of link to rebuilding the cluster yourself or links to the parts needed?
Expert:  Dan replied 2 years ago.
I have no links to rebuild cluster as that isn't something the service manuals cover or something practiced. Let me know if you have more questions, thanks.
