Yes, there are three. Two for the water jacket and one for the cam shaft.

Well, happy little friend, freeze plugs on a 1999 5.7L Tahoe are typically located on the sides of the engine block. They help protect the engine from cracking in cold weather by popping out if the coolant inside freezes and expands. Just remember to handle them gently and replace them if they show any signs of wear to keep your engine happy and healthy.
The holes in the cylinder block that allow the removal of sand used in the casting process are typically sealed by installing core plugs or freeze plugs. These plugs are designed to fit into the holes securely to prevent any leaks or debris from entering the engine block.
On a 2001 Isuzu Rodeo, freeze plugs, also known as core plugs, are typically located on the engine block. You can find them on the sides and rear of the engine block, where they help prevent coolant from leaking. They are often circular metal plugs that can be accessed by removing any necessary components for better visibility. If you're looking to inspect or replace them, ensure the engine is cool and the coolant system is drained.
They are on the sides and rear of the block. I am guessing that you are referring to the "Freeze" plugs. That term in itself is deceiving as these plugs were never designed to provide any sort of freeze protection. Many old timers call the "welsh" plugs but I suppose because they popped out when an engine block froze, they were incorrectly called freeze plugs. The caps cover casting blocks in the engine and are usually made of metal. The are located on the sides of the block under the heads and exhaust mainfolds but above the oil pan. They are harder to get at then they are to replace. I would suspect that if they failed you usually have other related issues as well. VBdenny

The motor has "freeze plugs" located in the front of the block (2, one 4 each side), think two down each side, and I believe two in the rear. If there's a lot of rust in the cooling system then over time it can and will eat a hole through any of the plugs, in your case possibly those in the rear, causing the leak. Freeze plugs are NOT to prevent the block from busting if frozen. They are holes used during sand casting of the block/heads and won't save a motor if it's subjected to freezing conditons.
At any automotive parts store.
To change the freeze plugs in a 2002 Ford Explorer, first, drain the engine coolant and remove any obstructions, such as the intake manifold if necessary. Then, use a suitable tool to carefully pry out the old freeze plugs. Clean the area where the new plugs will be installed, and tap in the new freeze plugs with a hammer, ensuring they are seated evenly. Finally, refill the coolant and check for leaks before starting the engine.
Any Auto Parts Store can provide this information. BTW, the are called Freeze Plugs or Casting Plugs, not Frost Plugs.
To normally install a block heater you must remove an expanstion/ freeze plug in tighten in the block heater. The 6 cylinder 4.2L engine unfortunately does not appear to have any such plugs. The V8 engine should have a screw in style block heater installed in the left front of the engine block just below the cylinder head.
If you can get to it, yes. But understand that there is probably rust and corrosion elsewhere in the engine and you probably have a few corroded freeze plugs that haven't given out yet. You may need to pull the starter and exhaust manifold to get to the freeze plug, and replacement plugs are available. Once they start to go it probably won't be stopping any time soon. A good anti-freeze with a rust inhibitor is certainly worth the investment if for no other reason than it prevents freeze plug failure.
