02 max. Im replacing the radiator Monday, how do you guys go about bleeding the system? I don't see bleeder screw. Thanks

 

I would help you...but I saw your thread in general discussion so I've lost all motivation to help you.

That said...the search function is your friend.

 

Don't be like that marry...il give u some if u want

 

I think you'll be assigned to work with george__

 

 

Haha

Look OP...no need to be a total lazy douche. Just do a search and you shall find what you are looking for, that simple really.

 

I never seen a bunch **** like I do on this forum.

 

 

Flush is the way to go...

1) Remove lower radiator hose (LRH) and drain radiator and reconnect.
2) Remove block bolts and drain block and keep heat to high with blower set highest.
3) If the block bolts are hard to get, then fill radiator with distilled water, remove upper radiator hose (URH) and plug the upper radiator hole at the radiator end with towel. Connect a water hose the one I got was from Home Depot for $5 and of 4 ft length, it is deep blue in color which fits snuggly onto the URH and clamp it and point the extended hose to a gallon bucket. Start car and keep filling the radiator with distilled water while thermostat opens and sends out the coolant out of the block via the URH to the gallon bucket.
4) Run thro 4G of distilled water, and after sometime its only water that comes off the URH.
5) Stop and reconnect URH and drain the radiator and fill the radiator with full strength Nissan coolant (leaving 1/2L for overflow tank).
6) Block has 3.5-4.0L of distilled water and radiator 3.5L of coolant (total capacity is around 7.5L including heater)
7) Start engine and cycle thro for the water and coolant to mix.
8) Fill overflow tank completely with 1/2L coolant and distilled water.
9) Purge remaining air in system but opening radiator cap on an inclined drivethro and keep running for 45 min.
10) All air is out of the closed loop system. Fill overflow tank to full and check levels for a week.

Flush Procedure

You'll need to flush the engine until clear water comes out to get it all.

1) Remove lower radiator hose (LRH) and drain radiator and reconnect.

2) Remove block bolts and drain block and keep heat to high with blower set highest.

3) If the block bolts are hard to get, then fill radiator with distilled water, remove upper radiator hose (URH) and plug the upper radiator hole at the radiator end with towel. Connect a water hose the one I got was from Home Depot for $5 and of 4 ft length, it is deep blue in color which fits snuggly onto the URH and clamp it and point the extended hose to a gallon bucket. Start car and keep filling the radiator with distilled water while thermostat opens and sends out the coolant out of the block via the URH to the gallon bucket.

4) Run through 4 Gallons of distilled water, and after sometime its only water that comes off the URH.

5) Stop and reconnect URH and drain the radiator and fill the radiator with full strength Nissan coolant (leaving 1/2L for overflow tank).

6) Block has 3.5-4.0L of distilled water and radiator 3.5L of coolant (total capacity is around 7.5L including heater)

7) Start engine and cycle through for the water and coolant to mix.

8) Fill overflow tank completely with 1/2L coolant and distilled water.

9) Purge remaining air in system by opening radiator cap on an inclined drivethrough and keep running for 45 min.

10) All air is out of the closed loop system. Fill overflow tank to full and check levels for a week.

 

^why not just take out the drain plug from the bottom of the radiator?
Take off the hose you say?

 

 

Thanks bro. Is the thermostat hard to do? It looks like its really tight spot to clean the gasket off the block from the top.I dont have a jack . Im doing the radiator off the ground. U think I should just leave the stat?

I do have those yellow ramps but idk if I wanna get under the car with it on cheap ramps.

you might as well do the thermostat when you replace radiator? You can also get new rubber bushings from the dealership if you want.

 

Thanks if I think I got enough room il do it

 

bumbing an old but important thread.
How long does it take to cycle through the fluid in the engine?

 

What do you mean by "cycle through"?

 

Isn't it a PITA to get the block plugs on these cars?

 

Yep.
Don't even try.

 

i meant how long do i have to let the car run with the upper right hose disconnected while i am adding water before all the fluid is exchanged. it was taking forever. was only coming out in a trickle

 

 

Overthinking it. Just pull the radiator, install new, and fill it up. What makes you think it needs completely flushed? I think a lot of times inexperience guys make things worse trying to work on them too much. Forget the thermostat. If it works, leave it be.
