where are block drain plugs?

[gride]

2005 ex330 closed cooled. how many plugs/hoses are there and roughly where are they located? if you know what size tools to use that would be a great help also.

The 5.7L engine has a block drain on one side and on the other side is the knock sensor. There is a plug on each exhaust manifold and one plug on the large hose from the circulation pump to the thermostat housing. You should also remove the hose from the trans cooler.

I don't know the details on draining the closed cooling system but you don't drain the block or pull the knock sensor or you will loose your coolant. Look on PCM's website and they should have a manual that will clue you in.

is there a perfect seal substitute from autozone b/c i couldn't find it.

gride, the engine manual is on this website to download, make it your best friend. If your closed cooling was factory installed then it should have the quick drain kit installed. There are hoses that run to the drain ports on the engine and exhaust system and then combine in one hose with nut on the end of it. Remove the nut and it drains the exhaust manifolds and engine coolant heat exchanger. On a 196 this hose is laying in the bilge of the boat next to the drain plug. Do not confuse it with the "quick drain" oil hose which runs from the oil pan and is usually secured on the top of the engine. With closed cooling and the fresh water drain kit there area ton of black hoses around the engine. Follow each one to make sure you understand how the system works. You might consider marking them with colored electrical tape for future reference.

After you drain that system you still need to remove two bolts from the pull end of the exhaust manifolds. You may or may not have them on the 5.7, again check your manual. Pull the impeller, replace with a new one, drain the water out and replace the old one, or store the old one in a plastic bag and reinstall it in the spring. Drain the water separator and replace it dry, don't lose the rubber washer. Drain the transmission fluid cooler, there is a nut you can remove to do this or you can just remove the hose. Check for low spots along the raw water line before and after the transmission cooler, lift them as you can to get the water out. Again, this is off the top of my head, the best, and as far as I am concerned only, real reference is the PCM manual which Jeff has made available on this site.

What are you using "perfect seal" for?

[gride]

the manual says to put perfect seal on the drain plugs when re-installing. i can't seem to find any real info what exactly it is and can't find that specific product online either.

[j2nh]

I use anti -seize (NAPA). Nasty silver paste that makes a huge mess if you get it on anything other than the intended bolt/threads.

[gride]

no napa here. if i say anti-seize to someone at o'reilly or autozone will they know?

Yes they will.

Gride,
I couldnt get a straight answer for the 2008 engine, but here is what I found out through trial and error

For the 2008 330EX
1) On either side of the block, there are knock sensors. When removed, coolant leaks out
2) Use a 1/2" extension on the V-drive plug
3) I used a cresent on the bottom driver side of the heat exchanger
4) The heater is also tied to the closed cooling (contains coolant)

This is about all I tried, but I work offshore and ran out of time and had to come to work.

Hopefully some we can get some answers for these engines, as the PCM manual is not clear

[gride]

ya i mean i've looked at my engine, read the manual a bunch, looked at diagrams, etc. im sure after i did it once it would be easier than putting together walmart furniture.

Hi gride . I think there is a substitute but I'm not sure yet. I will tell it to you if I am very sure on it.
