Bleeding the coolant system 04 RX8
 

Hello I am I'm need of propper bleeding procedures for the coolant system. I just replaced my radiator after it exploded when I shut the car off. I found out the hard way it's nothing like bleeding a regular car. Any help greatly appreciated thanks a lot -Matt

have you checked the DIY forums? Plenty of DIY info there...

Lift the front of the car up, unscrew the radiator cap, start engine, rev + warm it up, turn off when warm. That should get most/all the air bubbles out. You can also try this:

After performing repairs or any time cooling system coolant is drained, the cooling system must be purged of air. Use the following procedure below to remove air from cooling system:

1. Safely elevate front of vehicle on hoist. Elevating the front end only, at a steep angle will allow air trapped in system to escape easily.
2. Temporarily remove a coolant hose to the throttle body.
3. Fill coolant system with proper mix ratio of coolant / water per work shop manual.
4. Start engine N carefully monitor coolant level, topping off as necessary.
5. When coolant begins to flow from throttle body hose, air is bled from system.
6. Carefully attach coolant hose back to throttle body pipe. **Caution, coolant may be extremly hot!
7. Verify proper coolant level N add as necessary.
8. Check system for leaks.
9. Verify repair.

Thank you Ross the rapid response is much appreciated!! Thanks for the info

Is it the hose on the bottom left of the TB? I'm assuming I need to remove the intake to get to it.

i *think* it's the hose on top, but when I tried this coolant shot out immediately.
