How much coolant for t stat replacement only?
How much coolant should be expected to be replaced when replacing the t stat?
I just did a flush this past spring. A small leak at the housing presented itself even with RTV. I bought RRs billet housing. Turns out the t stat o-ring was crimped. During removal, I lost all fluid in the degas tank. How much fluid should I buy to top off?

They sell hose pinch off pliers, get two to clamp down on the rad hoses, it'll minimize the flow out of the radiator. I have the ones from HarborFreight, they work well.

This is what I do. Years ago I bought a light gray colored plastic oil pan with a pour spout on it. I use this pan for coolant work only.
When I go to use it, I rinse it with water and dry it off. This ensures the coolant drained into it stays free from contamination.
If you want to go the extra mile, you can strain the coolant through a cloth before putting it back in the degas bottle.

Since you will probably have to buy a gallon anyway (unless you think you lost more than two gallons of coolant), and also a gallon of distilled water. Mix up a quart or two of 50% each at a time in a pitcher and keep adding until topped off.

I just didn't know if 1 gal each or 2 would be needed if someone had a better idea of what I lost in the tank and upper hose. I bought 2 of each to play it safe. At least, I think that should be safe.
I'm not sure if it is fitting or ironic that I'm back working on the cooling system on the hottest day of the year. 112 degrees right now in N TX.

Distilled water is less than a buck a gallon. So it's worth diluting the coolant.

Those of us up north have to be **** about the ratio to prevent frozen/cracked blocks.
