I have a 2003 L36 and need to replace the UIM and LIM gaskets. I have the follwing part #*.

LIM Gm # 89017816
coolant elbows GM #24503423
UIM GM #89017554

My question is I also see the following part #* list for this

They have a special on shipping, only $8.94 flat rate.
upper-$49
lower$28
elbows $10each

Good deal.

Where did you get those 2 part numbers? GM seems to use 8 digit numbers so 1711317 may be a typo. A google search shows 89017279 as the lower intake for the 3.1 & 3.4'*.

You might want change the valve cover gaskets while you're at it. Some of us also get the throttle body gasket & give the throttle body a good cleaning. Fuel injector O rings are generally replaced but I'm not sure if I'd worry about it on a 2003.

Thanks for the info , sorry it'* been a while but the computer has been down.The 317 # was a typo and that # is now the 554#. will check out Intense Racing. I have 115k miles so I'm going to do the O rings and everything.

Thanks Again
