SOURCE: location of fuse box/panel for 2004 yukon denali xl

There are 2 fuse panels in the Denali.
One is a panel on the drivers side, its on the dash but facing the door.

The ohter is under the dash and above the pedals, this one is much tougher to access.

Your Owner's Manual should tell you where the fuses are that you need to access.

Mark your drive shaft coincidenly with the rear axle and tranny. Remove drive shaft. Press out the old u joints and press in the new. You will need a torch for heat and a lot of patience. Have fun!

SOURCE: 2004 Yukon XL Denali fuel gauge fluctuations

Your sending unit for the guage is part of your fuel pump in the tank. But first try your fuel pump relay, may be working intermittenly when you hit a bump or something. Or possibly a loose wire somewhere along the way. Much less expensive (worth a look).

Where is the knock senser on a 2002 lincon ls


Hello Antwan Davis,

It appears to be inside & (b'twix) the heads on top of the engine...

I remember seeing connections for two on MY 2004 Navigator...
(I'm getting pretty old... )

Most folks get "knock" issues by thinking they can get away with "REGULAR" gas...

Simple answer:
They Can't...!!

Simple test... buy some "LEAD FREE" octane booster...
add the recommended amount to your tank...

If the "KNOCK" goes away...You don't have to worry about deeper DAMAGE ...

It is very distinctive looking...

Check out the link below ... Hope THIS HELPS
(OH BY THE WAY... it is far cheaper to run he recommended octane than to buy these terribly cute OCTANE boosters.

Will a 2001 yukon denali radiator fit in a 2004 yukon denali xl?


Yes, as long as the engine is of similar size, you shouldn't have any problems fitting the radiator from a 2001 Yukon to a 2004 Yukon XL model. There are a couple of things to be aware of. The radiator should have the same connections on it as the one you are replacing for best fit, but are not required. If a mechanic is doing the work, they shouldn't have any issue resolving any concerns like auto to manual transmission differences...but playing it safe and getting the replacement from a like vehicle is best.

I have an engine code PO332 knock sensor 2 circuit low imput bank 2 what is this problem .the car is a 2001 gmc yukon xl .


The most likely cause of your code is a bad rear knock sensor. You should check the knock sensor wiring harness for corrosion. But if that checks out the sensor will have to be replaced. The knock sensor is under the intake manifold, although it's not too difficult to remove. Both knock sensors should be replaced along with the wiring harness, just because of labor involved in gaining access to the sensors. You could try clearing the code, it may stay off for a long time.
