On there way, ordered the radiator through bimmerworld for a total of 220 after shipping. The tan blade through pelican for a total of 40 after shipping.
Onto the story. Changed my valve cover gasket yesterday with some help. My help lost an extension turns out the extension was in the fan shroud, long story short, it ate my radiator and my fan. Back to driving the ranger...
Everything should be in today, pics of prior installation and finished product. Any tips on bleeding the system?
10) It really helps to have a friend lend a hand by sitting in the car revving the motor and keeping an eye on the temp gauge. Start off by removing the coolant reservoir cap and the plastic bleeder screw right next to it. Fill the coolant reservoir with a 50/50 mix of coolant and distilled water. Have your friend start the car, turn on the heater to full hot on the vent position and rev the motor to about 2500 RPM, if the temp gauge goes past the 12 o'clock position, shut the motor off, let it cool down and start over again. Watch the coolant reservoir, as the engine warms up the coolant level should drop, refill as the coolant is sucked out of the reservoir. Watch the bleeder screw hole also, when coolant with no air bubbles begins to overflow then you're almost done. It's a good idea to have some paper towels handy to mop up any overflow. Screw the bleeder screw back in (be careful to not break the plastic screw) and continue to rev the motor, you should see a continuous stream of coolant spraying in to the reservoir from the small hole at the top. Continue letting that spray in to the reservoir while your friend revs the motor for a couple of minutes, until the gauge hits the 12 o'clock mark, to ensure any remaining air is gone. If the heater is blowing hot air when you're revving the motor AND when the engine is at idle then your cooling system is properly bled. If your vents are blowing cool air at idle then you still have air in the system, try revving the motor more and/or squeeze the radiator hoses to help dislodge any trapped air. Once your system is fully bled, top off the reservoir and replace the cap. Check the coolant level in a day or two and top off as needed.
That's what I just ordered, still got to figure out the cheapest way to get it Downunder. Lifetime warranty on these units, so if you are planning to keep your car for 5 years, its probably worth the angst when you factor in a failed radiator on a trip. No more plastic end tanks or expansion bottles for me.
