I got this info,first hand from Seaview Chev in Lynnwood. When the Duramax first came out the Aluminum heads didn't handle the heat the way they thought they would and had lots of overheating problems.I thought that it was a well known problem?

Since then a friend bought an 02 Duramax and have towed their 39' fifthwheel all thru the states and have had no heat problems. They are also very pleased with the Allison tranny.
