Stop Leak Will Come Back To Bite You

Yeah that's what I'm thinking. Still, if you're trying to calculate percent of coolant vs water (which raises it's head whenever you've done a straight water flush, it's really handy to know the full capacity.

Too: wouldn't it be nice if the coolant measuring gizmos read in percent, not freeze protection temp? A work around: buy a decent one, then experiment: say first mix up and test a 60% solution, make a mark on the tester. Then dilute it to 50% and 40%, check with tester at each percent and mark.

I think temp is a factor too, so maybe do all these tests at room temp, ditto when testing the car's coolant.

 

Too complicated....50-50 is "standard". It works for 80% of the cars.
But places like north and south dakota, wyoming, and the very north where it's usually
below zero all the time, you do 5% water and the rest antifreeze. And different engine oil.
These are not the "standard", they are the exemption. Which is usually covered in the manual.

You don't NEED exact measurements for oil and coolant changes. Too many variables.
How level was the car? How long did you let it drain? How hot/cold was it?
Even if the system was completely dry, you put in the gallon, then run the system and install any extra
to "top it off".

 

I've got a booze making hydrometer. Maybe that'd work?

 

@cnc97 approach is probably best: put in 70%, with a system that's a got a liter or two of residual water, and you won't be far off.

 

It would be minute... so put 60-40 in it.

 

Dang sorry for the delay guys ! I haven’t been on in a while ! Thank you for all the advice . I’m bleeding the air system again because the heater isn’t blowing as warm as it should and I want to make sure the air bubbles are out. I got an oil change today and they said my oil filter was shredded into three pieces so this must have been from the engine replacement I just had because the oil guy at Walmart said “don’t go to them again” and I said I just purchased this engine and the last time I got an oil change it was here”.
