Cooling System or Antifreeze

Symptoms of a Blown Head Gasket

A blown head gasket may cause a number of different symptoms. Coolant in the engine oil, an engine misfire or oil leaking from the engine could all be a symptom. Each of these symptoms could also have other causes and an actual blown head gasket may show none of the above symptoms.

Replacing Engine Coolant

Replacing coolant is not difficult, but it must be done correctly. Improper replacement of coolant is worse than not changing at all. Many shops do the job improperly. Using a new car dealership is also no assurance the job will be done properly. Best is to find a cooling system specialist that uses OEM coolant and distilled water, or do the job yourself.

Antifreeze & Coolant Tips

The two primary symptoms of automotive cooling system failure are leaks and an overheated engine. Corrosion is the most common issue, largely caused by a lack of and improperly done maintenance. Properly replacing coolant is far more complex than most people realize.

How To Fix a Car's Heater

A modern automotive heater provides warmth in the coldest situation. When it fails, things can get cold in a hurry. Finding the cause is important and easier with a basic understanding of how the system works.

When Is An Engine Overheated And Why, Part-II

Modern engines are designed to run within a narrow range of temperature. Because the metals used in an engine, expand at different rates, excess temperature causes a great many problems. Above a certain temperature, permanent engine damage will result.

When Is An Engine Overheated and Why, Part-I

Internal combustion engines convert fuel into mechanical energy and a lot of heat. When the heat of an engine is not controlled, by the cooling system, things get out of hand very quickly. At what temperature is an engine considered overheated and what happens when it is?

How A Radiator Works and Preventing Radiator Problems, Part II

There are many places that cooling systems may leak, some obvious and others difficult to locate. Accurate diagnosis and repair will keep the problem from expanding drastically.

How A Radiator Works and Preventing Radiator Problems, Part I

Years tend to slip by and with cars, this is no exception. It is easy to forget about the radiator. Radiators get rid of heat generated by the engine. When they fail, the results will be very clear.

Engine Thermostats, Fuel Mileage and Over Heating

Most folks realize an engine thermostat can cause a vehicle to overheat. Did you know thermostats are also one of the leading causes of poor fuel milage?

Preventing Water Pump Leaks and Problems

Water pumps are often likened to the heart of the cooling system. When the pump fails, the results are not pleasant. Most water pump failure can be prevented with a few simple measures.

Ford 4.6L Plastic Intake Manifold Problems

The 4.6L Ford engine has been installed in millions of vehicles over the years. It is the engine of the very popular Ford Crown Victoria, Mercury Grand Marquis, and Lincoln Town Car. These engines use plastic intake manifolds and from 1996 through 2001 there was a problem that can leave drivers stranded.  The problem is a sudden cracking of the intake manifold.

GM V8 Losing Coolant With No Apparent Leak

If your General Motors SUV or truck is losing coolant, with no visible signs of a leak, the source may shock you. Worse, allowing the problem to go on may well mean a new engine.

Dexcool, Coolants and Proper Service

Search the web, and you will find huge amounts of mis-information on engine coolants.  This is especially common in the case of the orange GM coolant, Dexcool.  Statistically, I see no less problems with green, yellow, red or any other coolant on the market.  Properly serviced, all coolants work well.  Improperly serviced all coolants will have problems.

Vehicle Temperature Controls

Automotive climate control systems are convenient and dependable. With dual-zone climate control we can even select our individual temperature preference. We need several components to make this happen. When things go wrong, it takes an understanding of the system to find the problem.

Leaking Intake Manifold Gaskets

Late model General Motors vehicles have had more than their share of problems with intake manifold gasket failure. Many times these vehicles come to us, leaking again after having had the intake gaskets replaced elsewhere. Any number of things have been blamed, from Dexcool coolant to defective gaskets. I feel neither of these adequately explains the large number of repeat failures suffered by these engines.
