That the right stuff?

yup. make sure to check the price at the nearest NAPA, and have them price match it.

around here NAPA is significantly cheaper than O-Reilly on Zerex GO5.

One quick question, can I use filtered water? Or does it have to be distilled water? I forgot to pick some up last night

There's a large gap between "can" and "should".

[NCUNLIMITED]

so that's a no?

Distilled only. I'm pretty sure it actually says that on the radiator top

hey how's the price of the premixed compare to mixing your own?

There is no premix Zerex

I could have swore I saw it mentioned in that oreiilly link above... not important though I was just curious.

Premix Zerex is 11.50

personally, I buy the undiluted. here's my version of the flush procedure...

1. buy an antifreeze tester, 5 gallon bucket, antifreeze drain pan, a black sharpie, a medium sized plastic funnel, 2 bottles of undiluted Zerex GO5, and 4 bottles distilled water.
2. drain coolant into drain pan to be properly disposed of. don't dump it in your yard or flush it. you can use old windshield washer fluid containers, milk jugs or your distilled water jugs to cart it off to be recycled.
3. flush the cooling system completely with garden hose flush kit, as directed by instructions. water should run clear before finished.
4. drain system completely (tap water)
5. refill with distilled water (~2-2.5 gallons)
6. if thermostat is not removed, run engine warm. if removed, just run it. (circulate distilled water)
7. let cool & drain again. if water is still contaminated and does not run clear, return to step 2.
8. if not draining from engine block plug, dump about 1/3 gallon of undiluted Zerex into the radiator to offset distilled water still held in engine block. Set this bottle aside. if you drain the block, skip this step.
9. take unopened 1 gallon Zerex bottle & 1 unopened distilled water and dump them into 5 gallon bucket. mix well with paint stirrer or whatever is clean & handy.
10. use antifreeze tester to verify concentration of bucket, so you know how to use & read it.
11. take contents of 5 gallon bucket, dump into empty Zerex GO5 container until full, using funnel. mark 50/50 MIX on the Zerex container with black sharpie.
12. put funnel on radiator opening, and dump your new 50/50 mix into the radiator until system full. as the radiator appears full, squeeze the upper radiator hose to push out as much air as possible. also fill the overflow bottle to the HOT mark.
13. put antifreeze remaining in 5 gallon bucket into 50/50 MIX bottle.
14. warm engine up. there will be air in the cooling system. if you have an air bleed opening on the thermostat, over time the air will be vented into the overflow bottle, and antifreeze will be sucked into the radiator from the overflow bottle. Continue topping off the overflow as necessary. It should read on the cold mark when the engine is cold, and at the hot mark when the engine is at the normal operating temp of ~195-210°F.
15. after driving for a few days, verify antifreeze concentration with tester at radiator cap. if concentration is too low, add 100% undiluted antifreeze to overflow bottle or radiator. if concentration too high, add distilled water to achieve desired 50/50 concentration.
16. if you must drain some to keep system from overflowing, make sure drain pan is clean. you can save this basically new antifreeze by pouring it back into the 50/50 MIX container, and adding undiluted or distilled as necessary to maintain desired concentration.

After completion, you should have a partial 50/50 mix bottle, and a partial 100% undiluted bottle.

The total coolant volume of the 4.0L is about 2.6 gallons (10 liters), and the block itself will hold quite a bit, so just draining the radiator won't do it.

Also, regarding the flush kits - note many of them have a black rubber gasket, which may NOT be compatible with HOAT coolant. It will deteriorate over a couple years time...at least mine did. Replace this gasket with a regular silicone garden hose gasket.

Nice Unlimited I been waiting for the little write-up to show it's head somewhere for a bit now

I haven't checked my condition since I got it ...that said I'm sure you can imagine I'm too lazy to look it up right now...do you care to mention where I should look for the plug so that I can drain the block as well? Also, that's a freeze plug right? Do I recall correctly that once removed you have to put a new one in its place?

Seriously though, thanks for those instructions.

it is not a freeze plug. there is a small drain plug on the rear drivers side of the block (IIRC), it uses a 3/8" or 1/2" square drive if memory serves me correct. Since my coolant was clean with no signs of corrosion, I didn't mess with it because the space is kinda tight with the two mini-cats & trans lines there.

much obliged sir. I think I'll check the condition and watch the flush material and skip it if all else looks good. Thanks again
