2000 K2500 454 a/t 4x4 w/ac Long weekend ahead, so I want to make a few repairs. The intake is leaking again (replaced 3 years ago). I did not do it, so I am looking for some advise. What all parts should I get besides the upper and lower intake gaskets? I have coolant, oil and filter. Are there any special tools I will need? Should I replace the thermostat? Are there any 'tricks' or 'short cuts' I should know about? Or anything you can tell me from past experiance will be appreciated. Thanks.
