Coolant Changing Question

My Ph is about 8.5. Hardness is OK and alkalinity way, way low. I think they call it litmus paper and landscapers use it to test the Ph of soil. You don't need pool test strips to test for chlorine and other chemicals because they are fairly expensive. If you know someone with a pool ask them for a strip and they'll probably give you a few.

I figure after five years it could stand cleaning so I got a can of flush, put it in and drove it for a day then drained it refilled and drove around an hour, drained it again refilled and put it to bed for the night. When I did the flush drain I caught some and it was pretty brown looking but nothing terrible. This morning I drove it a few miles to get the t'stat open, drained it and refilled then drove it several miles again then drained it put in the 50/50 mix and water and ready to rock.

PH greater than 7.0 is basic and lower than 7.0 is acidic. So, from what I see, I'd rather have it on the basic high side than low in the acidic range. Click here to learn more about pool and spa water chemistry. http://www.aquachek.com/chemistries.asp?l=2 then scroll down and click pH.

CAPISH?

Since starting this thread, I have googled a lot of (Auto ph recommendations) and all suggested to keep ones coolant PH between 8.5 and 10/0.
Just my findings.

I read you 5/5 Rob. They had some kind of cooling system conditioner at WalMart becside the flush I used and I didn't pay it much attention but next time I wander that way I'm going to read the label. Starting to get real hot here and I take our lil' girl doggie to work with me on service calls and I let the car idle a lot with the A/C on so my best girl friend won't get to hot. Every stop I pop the hood and raise it figuring it will save a few degrees and let the A/C do a better job. Have to say, AC works so good you can hang meat in there when it's 100F outside.

HA! Wait'll the heat index is 105F and the humidity is 85% and I'll show you how to sweat. We're on an island on the SC coast half way between Charleston and Savannah surrounded by water so humidity is the order of the day. Yup, been a good learning thread and sure 'preciate you throwing it in the ring for discussion.
