How many gallons of 50/50 premixed antifreeze solution does my my 2001 Nissan xterra 3.3l 6cyl vehicle's radiator hold?

it does not use antifreeze. you will need to buy Dexccol premixed 50/50 coolant. There is no universal coolant, use Dexcool only, it is red. you should never ever add water, only premixed coolant.
the premixed is good to -40 degrees F.

If the reservoir is empty, you may want to start out by draining your radiator completely and starting over. there is a petcock valve at the bottom of the radiator. EPA Says you can't drain it onto the ground, but that's your decision. Anyway.....Buy full strength antifreeze. Take a empty gallon jug (could be a gallon milk jug so you can see more easily) and mix one half antifreeze to one half water.Take the cap off the radiator and add it it there.When it is full, put the cap back on the radiator and crank your vehicle to circulate it.Then start adding the antifreeze/ water mixture to the reservoir.As it goes down keep adding until it levels out at the normally hot line on the reservoir. As for the type of antifreeze........it's basically all the same which is Propylene glycol. CAUTION ! DON"T REMOVE THE RADIATOR CAP AFTER THE ENGINE HAS WARMED UP ! Hope this helps.

just buy the premixed 50/50 antifreeze and fill to coolant fill line on your expansion tank. probably wont take much more than 1 gallon provided you don't have a bad leak.

if your radiator light is on. means your water level in the radiaror has dropped 1/3 of it's fluids. get a gallon of 50/50 antifreeze(its already premixed) just add it into the radiator. for best results start car when it's cold start adding intill full

50/50 with water.v6 capacity is 2.5 gallons. make sure your antifreeze is not already premixed 50/50 with water if it is just our it in. if its strait antifreeze mix it 50/50 with water. and if you did not get all the antifreeze out of the block it will not hold 2.5 gallons. refill procedure is fill the system up install the cap start the car watch the temperature hand till it comes up to normal stop the engine at this point and wait till it cools refill once more. this allow the engine to remove trapped air and open the thermostat for proper refill.

normally 2-3 gallons if you use the premixed 50/50 coolant, if you use straight coolant you will need to mix 50/50 with distilled water. the cooling system will hold approximately 3 gallons of coolant total

On the 4 cylinder you will need 1 1/4 gallons of antifreeze mixed with an equal amount of distilled water for a 50/50 mix. On the V6 you will need 1 5/8 gallons of antifreeze mixed with an equal amount of distilled water for a 50/50 mix. Make sure and use the correct type antifreeze.

If you are draining your radiator, or just need to add some, there are a couple of options. You can either buy antifreeze in a 50/50 premixed solution, or purchase one gallon of antifreeze and 1 gallon of distilled water (less than $1.00 at your local grocery store) and mix equaly in another container that way you have a proper mixture in your radiator. The 50/50 mixture comes in an orange color and the full strength comes in the traditional green color.

Always fill you radiator & resevoir with a 50/50 mix of coolant / water. Your vehicle should have dexcool which is a red/orange colored coolant. You can buy a universal equivalent which is premixed and is yellow (not green). It is safe to add universal coolant but not green antifreeze. Premixed (it will say on jug) would be your safe bet. Fill the radiator, add to overflow tank to full cold line, run vehicle until fully warmed up. Let cool back down & then recheck.
Don't forget to check for leaks....it is not normal to have your coolant get that low. You likely are leaking coolant.

If this helps please rate me!
You can do it.

Drain plug is on the bottom of the radiator. Should have a tab for the plug. PLUG DOSN'T COME ALL THE WAY OUT, you're only able to twist it so far. IF your confused, just undo lower radiator hose and have a big bucket. The anitfreeze you put in your car has to be a TOTAL mixture of 50/50. You can buy premixed 50/50 for a HIGHER price! If you don't want to pay that much, you can get STRAIGHT ANTIFREEZE. If you have an extra gallon jug around the garage, fill half with water and half with STRAIGHT antifreeze and tada! You got 50/50 antifreeze. Hope this helps ya.
