Radiator fluid or coolant becomes corrosive over time and damages the cooling system. Manufacturers give recommendations for replacement, but they can be confusing. Because coolant depletion is a chemical reaction, time if far more important than mileage. With a five year or 100,000 mile recommendation, five years are the key.
Testing the pH of coolant gives a pretty good idea. New coolant has reserve alkalinity and measures 8.5 or higher. When coolant reaches 7.0 the reserve alkalinity is depleted and damage may begin. This is a good time to replace.
Rust and sediment can accumulate in the cooling system. Flushing the radiator helps keep the cooling system clean.
You don't, unless you are flushing the system. Use distilled water and add it to the coolant recovery bottle - and it needs to be mixed with coolant.
Heater core (radiator) needs to be cleaned or changed
Just flushing the radiator, no but to flush the system, yes.
A cracked radiator can not be fixed. A cracked radiator needs to be replaced . A mechanic can replace one in a few hours.
Yes, it is
a very nice person who needs to start flushing the toilt. a very nice person who needs to start flushing the toilt.
Low coolant? Radiator probably needs flushing and/or replacing after 40 years. Bad thermostat? System airbound? Water pump not circulating coolant? Hoses collapsing? Bad radiator cap?
A raidator in need of a flush will not cause a battery drain.
following this link to see a picture of it. they are used in automotive application with radiator flushing machines http://www.sherco-auto.com/hose.htm
It flushes out old coolant and particulates which have formed in your cooling system.
Mineral sludge from tap water. A good radiator flushing will help and then use proper coolant to help keep the sludge building up and blocking the radiator.
