Mine has 122,000 on it.Believe me i have spent a week looking into this and if you dont flush the systom you will have this problem and used the correct antifreeze.you cannot tell what head you have by looking at the block the problem is not there if you look at a head gasket you will see six holes inbetween the cylinder holes on the 2000 and 2001 head if you set the head gasket on the head and look at these holes you will only see three in the head but if you do the same w a 2002 and up head you will see 6 holes 2000 and 2001 this was a big water restriction so they changed it so the water could flow easier and help keep the motor cooler aswellmine barly moves of the blue mark since i drilled the holes out and replaced the head.I did this work myself there was no way ii was paying the dealership 3000 dollers when i could do it i have driven it for 40 miles since i did the job and have had no problems and like i said it barely moves past the blue mark now and before it would go halfway and above.
