How can i tell if my coolant leak coming from my water pump

The water pump is in front of your motor. If the coolant is leaking from under the water pump, then the gaskets on your pump need to be replaced. Depending on how many miles you have on your vehicle, you're better off replacing the whole pump, plus the belts and thermostat. Yes, new gaskets come with the pump.

The front and rear differentials on my 2007 Yukon Denali (72,000+ miles) have synthetic lube. My dealer recommends that the lubes be changed at about $100 each. The maintenance schedule in the owner's...

not unless you travel in extremely dusty/sandy roads. Most ppl dont change their fluids for the life of their suvs. If you drove thru deep water often i would also change it but the front and rears are sealed and synthetic fluids is man made and takes an extremely long time to break down.

When is the recommended change for a timing belt change?

Ok, first, GM uses a timing chain in its engines, which goes much longer than a belt. With the timing chain, you don't have to worry about changing it until you're having to worry about overhauling the engine. Some people will try to sell you additional shop work, but it's not necessary. These are known to go for more than 400,000 miles with no problems if the engine lasts that long, but are always changed when the engine is rebuilt or overhauled. I currently own a silverado with 120,000 miles on the original timing chain, an s-10 with 210,000 miles on the original timing chain, and a suburban with 135,000 miles on the original timing chain, just for a reference for you. Hope this helped you out.

Water pump for 2002 Yukon Denali

Your water pump can last an indefinate amount of time as there are no rules on how long this may or may not last.At this juncture I would check for any play or lose feeling(or roughness) in the shaft with the belt off and inspect for any signs of weeping through the bottom "weep hole".If it feels tight and no excessive coolant trail appears from the bottom hole,I would personally "keep on truckin" as a failing pump will exhibit these an other signs of failure before it becomes a major issue....
