Never had to do it recently, particularly due to the anti-dumping laws around here (thankful to our legislators for doing this, I like the SF bay...) I leave it to the service guys who can recycle/dispose of the old stuff cleanly. If you're going to the coolant route (one might wonder why I say that because isn't that the de facto standard? Read my next statement...), then the only difference between the Volvo and Prestone/Xerex/you-name-the-store -brand coolants is the cost. See similar questions...

Auto manufacturers have learned that a balanced coolant solution of water and ethylene glycol is an ideal mixture of carry off heat, under a variety of outside temperature extremes and operational loads. (air conditioning, heavy loads). Bad coolant: It is strongly advised against the use of ordinary fresh tap water in cooling system for two reasons: ordinary fresh tap water contains harmful chemicals and minerals like salts and iron which increase the formation of rust and scale.

Spark plugs and wires often require replacement by the time your car reaches 60-70k miles. www.fordpartsnetwork.com has these, or some have used MSD wires, which have lower resistance, part #32219. Copper plugs are recommended by many, but do require more frequent changes than platinum plugs. When attempting to change the plugs, be sure to have a LONG socket extension (10" is a good start), as the plugs are DEEP in the heads. See similar questions...

The license is a small file that is copied to the folder where GeneXproTools was installed and can be moved from system to system. How to restore the DEMO functionality? I have the Professional Edition, but I want to 'test' the ability for classification using about 5400 input variables. See similar questions...

Manual toothbrushes should be replaced every three to four months, when the bristles look worn or splayed and after illnesses such as colds or flu. See similar questions...

Most pacemakers will last between 8 and 10 years, after which the entire pacemaker or its battery and/or wire(s) need to be replaced. Replacing a pacemaker may be done on an outpatient basis or may include an overnight stay in the hospital. See similar questions...

A coolant additive is not needed. Use a good quality antifreeze, mixed 50/50 with distilled water, change the coolant mixture at least every 5 years, and your cooling system should stay healthy. See similar questions...

It is a fact that 40% of all engine failures can be attributed to cooling system problems. If inhibitors, pH, Nitrites, SCA (Supplemental Coolant Additive), % Antifreeze, Freeze Point and Acid Content are not maintained at the proper levels, coolants can reek havoc on an engine. See similar questions...

Engine coolants should be tested at least twice a year, once before winter sets in and again right before summer. POLARIS recommends every 500 hours or 3 months for Level I or Level II analysis and every 1000 hours or 6 months for Level III analysis. Education and training are key to understanding cooling system preventive maintenance and coolant analysis. Click on Training and Consultation on the Products menu to view the POLARIS training schedule. See similar questions...

The items that need replacement are the polishing pads, polishing compound and final spray. How often you need to replace them depends on two factors: See similar questions...

Because it's the right thing to do. And because we all have an obligation to preserve the resources in the school. See similar questions...

The coolant temperature sensor is located left of the throttle body and a few inches lower. It has a red plug. It is typical that these get corroded (both the plug and sensor). Many experience better performance after cleaning it. The Mass Air Flow (MAF) sensor directly measures the amount of air flowing into the engine. The sensor is mounted between the air cleaner assembly and the air cleaner outlet tube. See similar questions...

In an original generation I type smallblock engine, coolant enters the front of the block and circulates through the block's water jacket. The coolant is heated by the cylinder cases, and then this hot coolant is then routed through the cylinder heads and intake manifold before returning through the thermostat to the radiator.

Each situation will vary depending upon the specific water-hardness, type of machining application. As a general starting point, for both ferrous and non-ferrous metals, (aluminum, brass, steel or stainless) a concentration of 8 - 10% is used to establish a baseline. Gradually decrease the dilution by adding make up coolant until the optimum concentration is found for your particular application and situation. See similar questions...
