Is it wise to upgrade a Camry's fully functional stock radiator?
Answer: There's a saying that goes, "If it ain't broke, don't fix it." The same goes for the Toyota Camry's radiator. It does a sufficient job of keeping the car cool and will usually last the vehicle's lifetime. However, performance radiators may be considered if the engine is being upgraded since it may need more cooling power.
What are the ways to determine the source of a radiator leak? What should be done after the leak source is discovered?
Answer: If the radiator seems to be losing fluid as fast as it is being replaced, then it most likely has a leak. The source of the leak has to be discovered first. It can be found by visually inspecting the radiator while looking out for deposits of the colored fluid. Pressure test kits are also available and will let you fill the radiator with air before it is submerged under water. The air inside the radiator will escape in the form of air bubbles; the source of these bubbles will then indicate the location of the leak. Additives may be used to fix minor leaks in the radiator while more significant ones can be welded shut. If those don't do the trick, replacing the radiator will be necessary.
What is radiator flush and how often should it be done?
Answer: After quite some time, rust, dirt and other deposits will form and collect in your radiator. If these solid particles continue to grow unabated, they may block the tubes of the radiator, greatly decreasing the rate with which heat is released from your engine compartment. An overheating engine isn't a remote possibility when this happens. To stop the buildup of these solid deposits, the radiator has to be flushed at least once a year.
