1993 ETC-Nothing 126K SOLD
1996 Deville-Nothing 135k SOLD
1997 ETC-HG Failure at 100,026
1998 STS-Nothing 112K
2003 STS-Nothing 52K
2005 STS-Nothing 13K
2006 STS-V-Nothing 17K

rolled the dice one too many times but the engine was replaced previously so they split the cost and ended up paying 2020.26 for the HG repair...

who had the 01 hg failure?!?!?!

**Playdrv4me** · #7 (**permalink**) 10-29-07, 09:59 PM

That would be me. 2001 SLS, I traded it before it got real bad for the last 1998 STS I had. Though I still see the car driving around town so they must have fixed it up nice or thrown some goop in it.

If you still see it driving around are you 100% sure it was the HG then?

YES. Had the coolant tested.

My 99 went bad I think due to not changing the coolant on time. Anyway the gaskets went bad and the rings also so the motor was pretty much a total loss. For the eight grand it would have cost to fix I got a much nicer car my current 2000 STS. The deciding factor for me though was not the motor but the lighter interrior on the 2000 and the black interrior of the 99 was burning my A$$ in the summer.

It probably got fixed it's not like the car is not worth fixing. If mine lasts another 60 thousand like my 99 did then I will fork out the 2500 to fix it.
