Coolant flush ?

I also tested the old thermostat and at even 200 degree it would not open so hopefully that’s is all it was.

 

That would make it easy! How old was the old thermostat and hoses? Not the original, I hope?? Always a great idea to change that stuff out when doing timing belt package. And the idler / tensioner gizmos. And always with OEM parts, IMO.

 

I could swear I replaced the thermostat when I did the water pump and timing belt. But I can’t remember. It’s all new now. Hoses too!

 

Awesome. Toyota Pink SLLC and hopefully youre good to go. As others mentioned above, if youre concerned about a little distilled water still in your block, just dilute with a radiatir drain/refill annually yhe nect couple of yrs, and be sure to burp.

 

Do you think the test strips work best or just the one that resembles a turkey basted?

 

None of those!
Get a Refractometer

 

Never seen one of those. I’ll order one and give it a try.
