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:
1) What action will go a long ways toward prolonging the life of the radiator?
2) When does corrosion eventually take over and attack the innards of the system?
3) Why are heat exchangers difficult to clean?
4) 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.
