#08-03-10-005A: Use of Chrome or Chrome Plated Steel Valve Caps on Aluminum Valve Stems - (Mar 31, 2009)

Subject:Use of Chrome or Chrome Plated Steel Valve Caps on Aluminum Valve Stems

Models:2010 and Prior GM Passenger Cars and Light Duty Trucks (including Saturn)
2010 and Prior HUMMER H2, H3
2009 and Prior Saab 9-7X

This bulletin is being revised to include the 2010 model year. Please discard Corporate Bulletin Number 08-03-10-005 (Section 03 -- Suspension).
This bulletin is being issued to inform dealers about the use of chrome or chrome-plated steel valve caps on aluminum valve systems.
Dealers/customers cannot install a chrome or chrome-plated steel valve cap on an aluminum valve system. If this happens, the contact between the different metals results in galvanic corrosion, which will seize the cap to the stem and may fracture the stem when attempting to remove the cap.

Inform customers of corrosion issues when chrome or chrome-plated steel valve caps are used on aluminum valve stems.
Use only plastic or aluminum caps with aluminum valve systems.

That's what I was trying to say!

MS3DALE · 12-09-2010, 10:24 AM

Galvanic Corrosion?

WOW! I've seen that happen with Light Bulbs; esp. Aluminum base lamps in Aluminum Sockets.

Mine didn't do that.

They were only on for about 4 months though.

I guess if you really need "jewelry" type valve caps you could put some sort of anti-seize on the threads?

Redemption · 12-09-2010, 01:07 PM

anti-seize will work just fine!

I use rubber caps because the kids in the hood like to collect the fancy chrome ones.
