Any tricks in draining and refilling the cooling system for the 355 5.2 cars? I see there is a bleeder screw on the top of the water elbow above the thermostat. Does this need to bled out or do the return hoses to the burp tank handle the air discharge? Thanks in advance for any experiences or advice.
Watson, My brief coolant change procedure: 1. Remove underside trays to allow access to radiators and block. 2. Open expansion tank cap. 3. Remove plugs. Drain both radiators. 4. Remove plugs. Drain block both sides. 5. Install both radiator and block plugs with new o rings and copper washers. 6. Pump system down with my AirLIft system. Check system holds vacuum. 7. Fill system using the AirLift system. No air pockets or purging needed using this tool. 8. Using my wifes turkey baster, remove coolant from expansion tank to correct factory level. I use BMWs coolant product.
The 355 is self bleeding so no need to remove any bleeding screw. Just run it, and continue to fill up the coolant to the right level. Check the next day and top up.
I downloaded this document somewhere in FChat (I think) many, many years ago, and have done countless coolant changes using the steps that are outlined, with great results. HTH, YMMV. Image Unavailable, Please Login
OK. I did breakdown and buy an airlift system. The reviews are very good. I have never heard of it until now. I already have the turkey baster
Is it possible to use the Airlift system (or some other tool) to evacuate the system? In other words, suck out all the coolant so you don't have to bother with all the steps necessary to drain the coolant the traditional way?
