Ok can someone circle the hose that I should remove while trying to get all of the air bubbles out of the system?

I am confused of which hose i have to disconnect.

Is the throttle body hose the one that wraps around and is closer to the passenger side of the throttle body?

Did you include a picture?
This is REALLY easy. Look a the back side of your intake manifold. You will see a hose that essentially goes into the back side of the top of it. This is the ONLY hose there. It is about a 5/8" (.625) diameter hose.
You really can't miss it.
It is at the rear of the engine, okay? Points towards the front.

i just take off the radiator cap and start the engine. the air will bubble out. just keep adding fluid. when the fluid starts to back itself out you should shut the car off and let it cool down (w/ or w/o the radiator cap on). Repeat until you don't have to add coolant.


pretty easy.

that is pretty much what i do also.

The hose is located on the topside of the rear of the throttle body, near the firewall and the TPS. It runs down to the rear iron.....just disconnect it and watch it closely. As soon as you see coolant come out, quickly connect it to avoid a mess

Just playing devils advocate here but...

Why would this help alleviate more bubbles out of the cooling system?

Is it necessary to drain the car from the block also?
or is it ok just to let it drain from the radiator only?

ANd if i just let it drain from the radiator, will there be alot of coolant still left over?

Right now im looking at going with a 65 water and 35 coolant setup.

This would equate to ~ 5.5L of water and ~3.0L of coolant I rounded off =)

and if i dont drain the block how much Litres of coolant is usually in there?

its the highest point in the system.

Why wouldnt you drain the block? It's a 12mm bolt located on the driver's side of the center iron. Quite a bit of coolant is held within the motor, if you just drain the rad you're not properly 'flushing' your coolant

What about draining the radiator, filling up again with distilled water, driving it for a few heat cycles, then draining again. Wouldn't that pretty much clear most of the old coolant out?

Try one of these BEST TOOL I ever bought for a rotary! With this and a jack easy as pie to fix that air in the system problem.

+1 Agreed. Takes the hassle out of burping the system. Very easy, very quick.

how would you know your coolant to water mixture?

If you drain, fill, and drain, the coolant concentration will be very low in the remaining volume in the engine. Just use a hydrometer (is that was that this is called? Can't remember from my beer making days) to measure the coolant concentration. I'm not that particular about my coolant concentration. Frankly, I think a pretty wide range will work just fine. Keep in mind that I'm in a pretty mild climate.

When filling the system should i disconnect this hose while i am filling the coolant using the lisle funnel?

And should I disconnect this hose after the car is warmed up, when the thermostat opens.

All you're doing there is mixing the old coolant with water. You'll still have old coolant in the system even if you do that several times. It'll just be diluted with water.

With a cooling system as sensitive as this, I wouldn't cut any corners or fiddle with the ratio.

cheaper version of airlift, i use the nicer version of this for everything, works amazingly well. if you have an air compressor this is an essential tool. essential.
