How do you change the knock sensor in a 2000 suburban?
The knock sensor (depending on engine) can reside either above the starter, or under the intake manifold. 5.7L and 7.4L knock sensors reside above the starter, passenger side of the engine. Exercise caution when removing them, as they're also blocking the water/coolant block drain on that side. 5.3L, 6.0L engines have two knock sensors under the intake manifold--so you'd need to remove the intake manifold to access them.

What is the most likely cause of coolant leaking from the rear of the engine in a 2000 blazer?
You need to climb up and lean over the engine and run your fingers around the back 2 corners of the intake manifold and see if you get antifreeze on them. They are none for the intake gaskets to leak engine coolant. It is a common problem with the vortec engines. There are also 2 freeze plugs in the back of the engine where the fly-wheel is bolted to the engine that could be leaking engine coolant. There is also a heater core hose that goes into the rear left corner of the intake that could be leaking. The hose fits into a quick disconnect fitting that screews into the intake. It is common for the fitting to leak too,

Car knocking noise?
An engine with a knocking noise is almost always a serious condition but not always. When you say knock, if you are referring to what some would call a ping, then that is not so serious and can be caused by simply using the wrong octane fuel. If your engine requires premium fuel then use only premium fuel. If it requires regular then don't waste your money on premium as it will provide no benefit. The condition is more commonly called pre-detonation. It can also be caused by carbon deposit buildup inside the cylinders. Using the wrong spark plugs can cause carbon buildup and pinging or knocking. Dirty fuel injectors, a bad knock sensor and an engine running too hot will also cause a knock. But the most serious reason for a knock is worn crankshaft or piston bearings. The only fix for this is an engine overhaul. Have your engine diagnosed by a professional to see what is causing the knock. You may only need to have the carbon deposits removed to solve the problem.
Where is the engine plenum gasket in a 1999 Nissan quest 6 Cy?
The upper intake manifold may also be referred to as the intake plentum. If you are going to replace that gasket you might as well change the lower manifold gasket and knock sensor ( under the lower manifold with 1 bolt holding it to block). Do yourself a favor and CHANGE the knock sensor because they fail all the time on that engine. Read the repair manual (could be found at library or bought at parts store) and understand all the steps before attempting.
