Flushed coolant 3x now has crap in it now

[oil pan 4]

About 3 years ago I had parked my z28 while I was in japan.
A year and a half ago I came home and while I was there I changed the coolant. I flushed it 3 times with 3 different brands of cleaners.
Sence then I have put about 3000 miles on it sence I unparked it, insured, registerd and had it inspected.
I have also added a bit of that prestone all makes models junk. only one hit, less then a cup.
I was checking every thing out cause I'm going to new york this weekend. One thing I did was rinced all the crap out of the coolant res.
Then stuck a hydrometer in the mix to check the %'s of water and coolant.
When the Hydrometer pulled the sample and it was full of all kinds of junk mixed with coolant.
The engine was cold and had been siting over night and all kinds of stuff was in there.
I am going to fix it once and for all.
I ordered a filter head from advance and sunday I'm going to put it on the heater hose.
When I put it on I will have 2 filters, a dirt cheap one and a good one because the first one will clog right up I think.
I figure $20 for a coolant filter and 10 or 15 minutes to put it on insted of $50 for a new pump plus an hour or so to put it on.
Any one elso running coolant filters?

What good is trapping the goop in a filter, which then clogs up and overheats the car, when you want it outta there? Flush again. And again until it runs clear. Then fill with G-05?

Check this filter out.

I'd throw it on my car, but I have a new car warranty, they won't allow it.

Playing Russian roulette with several flush chemistries may not have been your smartest move, either - especially if you failed to flush it all out with multiple cycles of de-ionized or distilled water...

Get plenty of distilled water ready. Open you drain valve on the radiator. Remove your radiator cap, run the engine, keep adding distilled water through the radiator until it runs clear out the radiator drain. (Removing thermostat for this will make it faster, but not necessary) Run two more gallons through it after it runs clear. Shut off engine. Let all water drain out. Refill with some water and some radiator cleaner. Run engine. Drain. Refill with water, run engine, drain. Reapeat again. Repeat more if you feel necessary, you don't want to leave any radiator cleaner behind when you add antifreeze. Refill with 50/50 mix of antifreeze and water, figure this out by finding you cooling system capacity in owners manual and adding the proper amount of coolant and then finishing by filling with water.

What year is the Camaro? Zerex G-05 should be safe to use...

1) With the engine cold, remove the radiator cap and open the radiator drain plug and drain the radiator until it is dry then close the radiator drain plug.

2) Fill the radiator with distilled water. Put the radiator cap back on.

3) With the automobile parked, run the engine with the heater on high at the hottest setting until normal operating temperature is achieved for 10-15 minutes.

4) Repeat Steps #1, #2, and #3 at least three more times until the distilled water in Step #1 drains clear.

5) Drain, fill, and rinse out the coolant overflow tank 3 times with distilled water. I recommend removing the overflow tank while doing this but this is optional.

6) Pour in a bottle of either Prestone Super Radiator Cleaner or Zerex Radiator Super Cleaner into the radiator. If your cooling system is larger than 12 qts., use 2 bottles of radiator cleaner at the same time.

7) Pour in distilled water until the radiator is full then put the radiator cap back on. Fill the overflow tank with distilled water to the "full" or "cold" mark.

8) Drive the automobile for 4-6 hours (can be on and off over a few days). Be sure to constantly check the level of distilled water in both the radiator and overflow tank. Be sure to run the heater on high at the hottest setting all the time if you can stand it. If not, run the heater on high at the hottest setting at least 3 times for 10-15 minutes during the 4-6 hour period.

9) Repeat Steps #1, #2, and #3 at least three more times until the distilled water in Step #1 drains clear.

10) Repeat Step #9 one more time just to be sure the distilled water drains clear.

11) This would be a great time to install a new thermostat and gasket if you know how to do this. Some vehicles do not have a thermostat gasket. If yours has a thermostat gasket, be sure to have a small tube of black gasket sealant. Be sure to correctly apply it to both sides of the thermostat gasket.

12) This would also be a great time to replace that old radiator cap with a new one.

13) With the engine cold, remove the radiator cap and open the radiator drain plug and drain the radiator until it is dry then close the radiator drain plug.

14) Pour in straight coolant sticking with whatever your manufacturer recommends NEVER SUBSTITUTE TO SAVE MONEY! Use enough to achieve no less than a 50/50 mixture of coolant and distilled water but no more than 70/30. Refer to your vehicle's owner's manual for the correct capacity of your cooling system. If you have a 12 quart cooling system, you will need 6 quarts of coolant (1.5 gallons) to achieve a 50/50 mixture of coolant and distilled water. If you want a 70/30 mixture of coolant and distilled water, you will need to pour in about 8 1/2 quarts of coolant (2.125 gallons).

15) With a half full jug of distilled water, fill it up with straight coolant to have a 50/50 diluted mix for top off. Be sure to shake it for about 3-5 seconds so it mixes.

16) Top off both the radiator and overflow tank as needed. Put the radiator cap back on.

17) Keep a watch for any coolant leaks. Repair any coolant leaks immediately.

18) Repeat all of the above steps every 2 years.

I think using a garden hose and a back-flushing tee is a bad idea since city water has additives and chemicals in it such as chlorine, fluoride (except for Indiana), etc. Well water is even worse.

You can get a jug of "Sam's Choice Distilled Water" at Wal-Mart for $.59. It is a good idea to buy a baker's dozen so you have enough. A few more jugs won't hurt anything either especially if you have a large capacity cooling system.

I own a 1998 Ford Mustang GT. It originally used conventional green coolant. Since green coolant is starting to get hard to find, I replaced it with Motorcraft Premium Gold Engine Coolant (Zerex G-05) which I bought directly from a Ford dealership.
