Redline Super Coolant Water Wetter Flush help?

scruffydog

I just bought 5x 1/2 gallon Redline Super Coolant Water Wetter to replace my existing Anti-freeze Coolant. However, I need some help in the proper way of flushing the system.

So far what I've done is open then drain plug drained most of the Coolant and then I opened up the radiator cap (while leaving the drain plug off) poured regular water into the radiator filling port until it's no longer bluish color and comes out as clear water.

Now it's time for me to fill up and this is where I'm confused. I looked up the capacity of the Coolant needed which was about 5x 1/2 gallon coolant but I managed to fill up and topped off the radiator cap at only 1 and a 1/4 bottles.

I assume most of the Coolant system is still filled (if not majority of it) with water rather than the Super Coolant Water Wetter. Any idea what I should do next?

Cheers

Copied this from the 370Z service manual. I included the draining, refilling, and flushing directions. DO NOT REMOVE THE DRAIN PLUGS ON CYLINDER BLOCK, thats only for when you dissemble the engine block.
You can download the service manual at this link.

ENGINE COOLANT : Draining
WARNING:
INFOID:0000000004751764
• To avoid being scalded, never change engine coolant when the engine is hot.
• Wrap a thick cloth around radiator cap and carefully remove radiator cap. First, turn radiator cap a
quarter of a turn to release built-up pressure. Then turn radiator cap all the way.
1. Open radiator drain plug (2) at the bottom of radiator, and then remove radiator cap.

When draining all of engine coolant in the system, open water drain plugs on cylinder block. Refer
to EM-74, "Setting". O
2. Remove reservoir tank if necessary, and drain engine coolant and clean reservoir tank before installing.
3. Check drained engine coolant for contaminants such as rust, corrosion or discoloration.
If contaminated, flush the engine cooling system. Refer to MA-21, "ENGINE COOLANT : Flushing".

ENGINE COOLANT : Refilling INFOID:0000000004751765
1. Install radiator drain plug.
CAUTION:
Be sure to clean drain plug and install with new O-ring.

2. Remove air cleaner case (LH). Refer to EM-27, "Exploded View".
3. Install reservoir tank if removed.
4. Check that each hose clamp has been firmly tightened.
5. Remove air relief plug (2) on radiator left side.

6. Fill radiator, and reservoir tank if removed, to specified level.
• Pour engine coolant through engine coolant filler neck slowly of less than 2 (2-1/8 US qt, 1-3/4 lmp qt) a minute
to allow air in system to escape.
• Use Genuine NISSAN Long Life Antifreeze/Coolant or
equivalent mixed with water (distilled or demineralized). Refer to MA-14, "FOR NORTH AMERICA : Fluids and Lubri- cants" (FOR NORTH AMERICA) or MA-15, "EXCEPT FOR NORTH AMERICA : Fluids and Lubricants" (EXCEPT FOR NORTH AMERICA).

9. Install air cleaner case (LH). Refer to EM-27, "Exploded View".
10. Install radiator cap.
11. Warm up engine until opening thermostat. Standard for warming-up time is approximately 10 minutes at 3,000 rpm.
• Check thermostat opening condition by touching radiator hose (lower) to see a flow of warm water.
CAUTION:
Watch water temperature gauge so as not to overheat engine.

12. Stop the engine and cool down to less than approximately 50°C (122°F).
• Cool down using fan to reduce the time. A • If necessary, refill radiator up to filler neck with engine coolant.
13. Refill reservoir tank to “MAX” level line with engine coolant.
14. Repeat steps 11 through 13 two or more times with radiator cap installed until engine coolant level no B longer drops.
15. Check cooling system for leakage with engine running.
16. Warm up the engine, and check for sound of engine coolant flow while running engine from idle up to C 3,000 rpm with heater temperature controller set at several position between “COOL” and “WARM”.
• Sound may be noticeable at heater unit.
17. Repeat step 16 three times.
18. If sound is heard, bleed air from cooling system by repeating step 6, and steps from 10 to 17 until engine coolant level no longer drops.
19. Check that the reservoir tank cap is tightened.

Thank you very much! I will give it a try. Looks like I'll have to wait till the dealership's open during the week so I can replace the seals for each drain plug. on the engine block.
