Cooling system cleaner

What is the best thing to use to clean out the cooling system. Thanks Jerry.

 

Coolant flush.

 

Yup! if you have anything aluminum in the system (radiator, heads, intake) use a compatible coolant flush!
There are a number of good products out there, but please read the instructions carefully.

This works well.

 

Prestone coolant flush with a reverse flush kit installed

 

Or thise big fuzzy Hamsters on acid...

 

Diet Coke,really!Fill the system up with it,run it a day or two,drain and flush w/ water.

 

I used Zep formula 50 cut 50/50 with water.

 

I have read on ford barn guys are using white vinegar with good results,run it for a week and flush it out,it needs to be neutralized with baking soda after woods .

 

God I will try the vinegar today. Thanks Jerry.

 

Spick-N-Span is supposed to be good, it was good enough that one of the flushes started adding it to theirs with a notice "with Spick-N-Span" on it to increase interest.

 

i've used dishwasher packets with pretty decent results

 

That's how I do it too! Just be careful handling the squirrels. One bite and you'll peak for hours...

 

Use Baking Soda after the white vinegar ....

 

Oxalic Acid A.K.A. wood bleach.......I used a small tub of it in my cooling system a couple of years ago with great results. I drained/flushed the system, filled with water/wood bleach and drove it around that way for ten days. Drained/flushed/refilled again and no more cooling problems. If you have a hard time finding it try the local/independent hardware stores, I had no luck with Lowes/Home Cheapo type places.

 

+1 I believe it was an ingredient in the coolant flush of days gone by. I think GM still uses it in their in-house coolant flush.
