In the market of an h3 im seeing alot of 2006 models.. In my other post someone told me there's a way to check a vin and see if the truck is more likely to have the problem.. does anyone know the exact vin or numbers that would tell me if that truck would have the bad gasket? thanks! Or if possible post a link to the other thread where it would be located I cannot seem to find it.

 

According to the post in this thread, Tainter may be the guy to get the VIN range from... https://www.hummerforums.com/forum/h...try-buy-22812/. hopefully he can help out.

 

Found it! See link: https://www.hummerforums.com/forum/h...s-16269/page2/ Post Number 13 from DocOlds

 

This just made me a little nervous about mine....going to check it after work. I'm at 55k miles right now and it runs flawlessly, keeping my fingers crossed.

 

Im no expert on this topic, i just knew there was some info out there because i searched it on this forum before i made my h3 purchase... but you should know that not every h3 in the vin range is guaranteed to have the head issue. its just more common for H3s within that range. Read all the posts in the links i provided (specifically the second one) and you will get some info about it.

 

but it sounds like they found the problem and did a fix at a certain date ,right?
b4 that date id figure its likely to show up sometime.huh?

 

There is no "head gasket problem", nothing to do with gaskets.

From a post of mine 2.4 years ago:

There is a search feature here, like every other forum I can think of.

The S/Ns affected is any 2006 H3 lower than 287591 .... the first one started with 100,001, your truck build date will be Nov. 06 or earlier. Not all have the problem, but some could. The head issue affected not only the I5, 4s and 6s were subject to the same issues. Call GM with your vin# and build date (from the sticker in the driver's door jam) and ask.

Just in case you're gonna say, wow they didn't even build that many 3s? The VINs are assigned at the same shreveport plant building Colorados and Canyons. Their VIN sequence unit #s are mixed in and subject to the same TSB re: the head/valve issue.

The recall and extended warranty was for very early 2006s, those with the 3.5L L52 Motors built before March 31, 2006. That is not to say some 3.7L LLRs have never had a valve or head issue. All the Atlas motors built since 4/1/06 have the new hardened valve seats.

 

Just to defend the OP a little; from what i got out of the initial post, it sounds like Speed did try to search the forum but couldnt locate it. thats why the link was provided to the very thread that your 2.4 year old quote came from.

 

i love details. the 2.4 years intrigues me. thats 2 years and .4 times 12=4.8 months,which at 30 days per month=.8 times 30 or 24 days.
so its 2yr,4 mo. and 24 days old!

doc that had to take u some figgering!

im done for today,enuf damage

 

Amazing. You can do complex math, but spell at first grade level?


My 06 and 07 both had the head issue fixed under warranty. Expensive fix otherwise.
