If you have concerns about warranties on aftermarket filters and mufflers, read on. According to the experts at Donaldson Co., there is no need to worry about voiding your warranty if you purchase aftermarket filters or mufflers. However, you still need to follow the manufacturer’s recommended maintenance practices.
Donaldson points out that the Magnuson-Moss Warranty Act protects warranties. Detailed information on the act can be accessed at www.ftc.gov/bcp/conline/pubs/buspubs/warranty.htm.
Donaldson adds that it warrants its aftermarket products against failure due to defects in materials and workmanship for the period specified under the terms and conditions for the particular product.
Maintaining cooling systems prevents big problems
Most cooling-system problems have long incubation periods. It can take several years for corrosion, scale, rust and other deposits in the system to jeopardize everyday driving, according to The Penray Cos. A clogged radiator, if not replaced in time, can lead to a blown head gasket.
The radiator isn’t the only component being compromised. Poorly maintained coolant corrodes the water pump, which can lead to failure. Bad coolant also can cause scaling and overheating. The thermostat, hoses, cap and overflow system also must be working properly for the system to perform.
While many coolants and antifreezes guarantee protection for the life of the engine, Penray highly recommends regular maintenance and testing of coolant to ensure its condition and protection levels.
Here’s what to look for when checking coolant:
• Color – Coolant color indicates the type of coolant and how it is to be maintained. Mixing technologies and maintaining them incorrectly leads to problems.
• Clarity – Regardless of color, all coolants should be clear. If coolant appears cloudy or has particulates floating in it, this is a sign of bigger problems.
• Freeze point – Properly maintained coolant should have a freeze point of -34 ºF. This indicates a proper 50/50 mix of antifreeze and water.
• Chemical protection – Chemical levels must be maintained and monitored in coolant.
The easiest way to check the coolant is with test strips, which provide quick and accurate results in fewer than two minutes. Options are available for standard, extended life, heavy-duty and conventional coolants.
