Engine Coolant?

Question

i need to replace my car thermostat and decided to change the coolant at the same time and give tht system a good clean,

just need to know, how much coolant do i need to buy to re-fill the system...the owners manual and haynes manual dont say anything.......

i have a 1995 Astra does anyone know roughly what it is for this car or the average for all cars ?

i will be completely draining the system and refilling

Answer 1

look in the capacities section of the haynes manual and macke sure you check it a few days after so it up to the top

Answer 2

Depends, if you are only going to drain the radiator, replace the t-stat and refill the radiator then a gallon of 100% antifreeze will do. If you plan on doing a completed flush buy 2 gallons of 100% antifreeze. In the end you want a 50/50 mix, when you by the anitfreeze get a tester also so you can check the mixture.

Answer 3

Fill until the overflow bottle reaches the line. After the coolant has been changed and the car has been running with the heat in the car blasting away for a few minutes, you'll probably need to top up the overflow bottle again. The most important part is to not overfill. Stay at the line.

Answer 4

Just go get three gallons of it and do this. replace the thermostat and then leave the cap off and engine running as you fill it.
fit the cap on loose (half turn) and idle the engine. Once the level has dropped that means that the thermostat has opened and you need to top it off. you will have to do this a few times untill after the engine gets warm and opens that thermostat. then it is just a matter of topping it off.

Answer 5

Most vehicles require about 2 gallons, unless the engine block is drained. Get 2 gallons of 50/50 antifreeze/water mix from your dealer and just pour it in.
Never run straight antifreeze, because water is required to activate the lubricating and anti-corrosion properties.

Answer 6

Coolant only comes in gallon jugs. about a fifty/fifty ratio is good or you can purchase a hydrometer at the parts store for like about $2 it's usually a red bulb on top with a glass tube with differant colored balls in side of it and a small red hose attached. It will tell you how much cooling protection you have and you can make up your own mind

Answer 7

if you have a 4 or 6 cyl. engine, 2 gallons will definately be enough because you are going to mix it 50/50 with water to make 4 gallons (you will probably only need 3 gallons but better to have extra). if you are buying premix then I would buy 3.

Answer 8

I run almost straight antifreeze. I always buy distilled water to mix.
