wat is the percherader in bleeding out the coolant system on an sr20det?
do you mean the complete procedure or just to get the last bit of air out of it? I'll assume you mean the last bit of air.... to get the last bit of air out, have car running and warm,interior heater on full tilt on hottest setting, keep squeezing the coolant pipes to get air out as your topping up the rad the whole time, and then the Lil trick is to jack the front of the car up while doing the above, suddenly you'll go "oh fuck where's me coolant gone" so be at the ready to top it up again as needed. you'll know when its done when you just cant get any bubbles appearing in the rad, and the heater should be blowing well hot inside the car. take her for a spin and keep an eye on the temp, check rad again to see if it needs topping up.
thats pretty much it.
ps: let it cool down abit before ya check it after the spin....
ya lad just to get the air out of the system cheers for that
On the coolant outlet from the block to the top of the rad there is a bleed screw. Open this when filling the system so any air will be pushed out. When the system is full, start the engine and slowly remove the bleed screw so any air left is pushed out by the pump pressure.
The rad top pipe isn't the highest point in the system so squeezing that won't remove all the trapped air.
hence jacking the front of the car in the air. i know someone who rung the threads where that bleed screw is, and so from then on iv tented to leave that lil fellow alone. to be sure to be sure........Quote:
