I. Reading Exercises:
Exercise 1. Read and memorize using a dictionary:
clutch; coolant ; core; fan; height ; hose; inlet; load; outlet; steam; tank; thickness; width; |
Exercise 2. Answer the questions:
What action will go a long ways toward prolonging the life of the radiator?
When does corrosion eventually take over and attack the innards of the system?
Why are heat exchangers difficult to clean?
Why some "value priced" replacement radiators may not cool as well as the original ones?
Exercise 3. Match the left part with the right:
1. Lack of maintenance can also allow |
a) rows of tubes, increased thickness and/or a more efficient fin and tube design to improve cooling performance. |
2. The most vulnerable components are the radiator and heater core, especially |
b) a buildup of rust and scale that can clog a radiator or heater core. |
3. Aftermarket "heavy-duty" or performance radiators typically have additional |
c) part of a "cooling module" that includes the A/C condenser and fan. |
4. On some newer vehicles, the radiator is |
d) lead-soldered copper/brass heat exchangers in older vehicles. |
Exercise 4. Open brackets choosing the right words:
On some newer vehicles, the radiator (are/is) part of a "cooling module" that includes the A/C condenser and fan. Some of these can (be/been) difficult to remove and may have to come out from the bottom rather than the top. Separating the radiator from the other components may also (are/be) a chore. And if it is a really new vehicle, the radiator may not yet be available as a separate item, which means you (has/have) to replace the entire module at added expense.
II. Speaking Exercises:
Exercise 1. Describe coolant; core; heat exchanger; service life; using the suggested words and expressions as in example:
coolant substance; fluid; cooling; part; device; heat; to generate; Coolant is a substance, ordinarily fluid, used for cooling any part of a device in which heat is generated. |
core central part; a body; structure; |
heat exchanger device; automobile radiator; to transfer; heat; fluid; environment; |
service life length of time; a machine; tool; apparatus; device; be operated or used; economically; breakdown; |
Exercise 2. Ask questions to the given answers:
Question: ___________________________________________ ?
Answer: The average service life of an OEM copper/brass radiator is six to 10 years.
Question: ___________________________________________ ?
Answer: Excessive heat can kill a radiator, too.
Question: ___________________________________________ ?
Answer: For some applications, you may also have a choice between an aluminum or copper/brass replacement radiator or heater core.
Question: ___________________________________________ ?
Answer: Aftermarket radiators may not always be an exact match with the original because of consolidation
Question: ___________________________________________ ?
Answer: The old radiator cap should not be reused unless it has passed a pressure test.
