The proper ratio depends on the temperatures your vehicle will be operated/stored in. Typically, a 50/50 ratio will be just fine. If you will park/store your vehicle in extremely cold (sub-zero) temperatures, you can increase to 60% coolant to 40% water.
yes its the same place it might have an extra outlet for the turbo.
50/50 for most application
A cracked turbo on a 1990 Eagle Talon TSI can potentially lead to burning coolant rather than water. If the crack allows coolant to enter the exhaust system, it can result in white smoke, which is a sign of burning coolant. However, if the turbo is cracked but not leaking coolant, it won't directly cause water to burn. It's essential to inspect the turbo for any signs of damage and address any leaks to avoid serious engine issues.
You need a 50/50 mixture of water and antifreeze.
Usually 50 / 50 mix ( Ford states not to exceed 60 % antifreeze and preferably distilled water )
Any Ethylene Glycol based coolant mixed in a 1:1 ratio with water. Prediluted means it is already in the correct ratio.
50/50
Genuine Subaru Coolant or equivalent (50% water & 50% Ethylene-Glycol basis coolant) as per page 10-13 of the "OWNER'S MANUAL".....
Minimum 50/50. Maximum 70/30 (coolant/water).
a 50/50 mix of good quality antifreeze and water
50% water to 50% coolant is the standard unless you live in a very cold climate where it goes down to -25 degrees F or lower, then you may want to mix 25% water to 75% coolant but never straight coolant.
50/50 50% Dex Coolant and 50% Distilled Water. This is assuming you did not buy a premixed gallon of coolant. This will protect you to -40 F.
