How do I replace my coolant?

Cooling FAQs
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.

When should I replace my coolant fluid?

Recochem Inc. - Products - FAQs
Answer: In general, follow your OEM's (Original Equipment Manufacturer) guidelines. If you do not have a guide and are using traditional coolant, then change every two years. Extended Life Antifreeze/Coolant is every 5 years or 250,000 km. Extended Life Heavy Duty is 1,000,000 km, 12,000 hours, or 4 years, whichever comes first. It is important to note that you should check a coolant system at least twice a year.

What Is Good Coolant?

FAQ : The Pressurized Cooling System
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.

How do I refill the coolant system?

Maintenance
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.

Where is the coolant temperature sensor located on the VE?

Frequently Asked 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.

How does coolant flow through my engine?

Page not found - ThirdGen.org
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.

How is Liquid Ice Coolant diluted?

Machine Tool Industrial Lubricants | Coolants | Liquid Ice
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.

Will Liquid Ice Coolant Foam?

Machine Tool Industrial Lubricants | Coolants | Liquid Ice
NO! Under most circumstances, Liquid Ice HP, HPX or VP Coolants will not build up foam in your coolant tank or Sump. Under high pressure (200 - 1000 PSI), aeration will cause it to look white instead of its normal clear, colorless appearance. This is perfectly normal, and the coolant will quickly revert back to the fully liquid state within a matter of seconds.

What can you tell me about engine Coolant?

Auto Mechanics", "Auto Repairs","Mechanic Talk", "Certified ...
Coolant is what keeps your engine operating at proper temperatures. However as coolant ages, its efficiency slowly declines. Older cars had large radiators with excess capacity. Today's cooling systems are designed "just big enough". And a little deterioration can soon cause big problems. The two main ingredients in "coolant" are water and antifreeze. Antifreeze is ethylene glycol based, which basically never wears out.

Where do I get the coolant for Freeze branding?

L & H Branding Irons
With freeze branding you will need to cool the irons down to a temperature that will allow you to achieve a clean consistent brand. The coolants that are used to perform this task are either liquid nitrogen or dry ice and alcohol. You should be able to pickup the coolants at any welding supply company or artificial inseminators carry the liquid nitrogen for use in storage of their semen.

How does coolant wear out?

Lube City | FAQ
Engine coolant (antifreeze) has additives that help prevent rust corrosion, scale buildup, chemical breakdown, and the formation of acid, which all contribute to the likelihood of a cooling system failure. Like engine oil, these additives do wear out because of the higher Rpm's and operating temperatures of today's engines. It is critical that coolant be replaced before it turns acidic and destroys the cooling system it was meant to protect.

How can Contaminated Coolant Harm my vehicle?

Lube City | FAQ
Contaminated coolant can cause deterioration of metal components in the radiator, heater core, engine block, plugs and thermostat. Rubber components such as hoses and gaskets react by leaking, causing coolant loss, resulting in overheating and engine failure.
