The coolant in the Atenza is added to the radiator, which is located on the left side of the engine compartment. It is a plastic container containing coolant, and you can add more by opening the plastic cap on top. The Atenza is equipped with two naturally aspirated engines: a 2.0L and a 2.5L. In terms of interior features, the Atenza comes with Mazda's MZD Connect system, in-car WiFi, and an ADD head-up display system, among other technological configurations. It also features upgraded NVH for improved cabin quietness. The Atenza utilizes the SKYACTIV-Chassis technology, incorporating a high-performance MacPherson strut front suspension and a multi-link rear suspension. Additional features include a heads-up safety concept cockpit, an integrated center armrest, an EPB electronic parking brake, a floating central information display, and an ADD head-up display system. The vehicle dimensions are 4870mm in length, 1840mm in width, and 1450mm in height, with a wheelbase of 2830mm.

The coolant for the Atenza is typically added to the expansion tank in the engine compartment. That tank is usually made of translucent plastic and located near the base of the windshield, with clear MAX and MIN marker lines for easy reference to the fluid level. It's crucial to ensure the engine is completely cooled before adding coolant—operating right after parking may cause burns or splashes due to thermal expansion of the hot coolant. Having driven an Atenza for five years, I developed a habit of checking the fluid level either several hours after parking or in the morning. If it's below the MIN line, I slowly pour the appropriate coolant using a funnel, being careful not to exceed the MAX line to prevent overflow. Coolant isn't just for preventing winter freezing; it also protects the engine from summer overheating and reduces corrosion. I recommend using Mazda's factory-recommended formula and avoiding mixing brands to prevent chemical reactions that could damage the system. Long-term neglect of coolant checks can lead to engine overheating and costly repairs. Remember to check at least every six months to keep your car running longer.

As a daily driver of an Atenza, I found that the coolant refill location is under the hood at that white plastic expansion tank. It has a small cap that can be easily twisted open without tools. The prerequisite for operation is that the car is parked and cooled down, such as being turned off for more than two hours to ensure safety. I once almost got sprayed by hot liquid when I was in a hurry to add coolant, which was very dangerous. If the fluid level is low, buy the same type of coolant from the supermarket and slowly pour it in using a funnel, not exceeding the upper limit. The main functions of coolant are to prevent freezing in winter, dissipate heat in summer, and prolong engine life. I do a simple check every quarter to ensure the level is in the middle range, which saves money and hassle, avoiding the trouble of breaking down on the road. After adding coolant, remember to tighten the cap and test drive to make sure the temperature gauge is normal, then it's okay.

I've been driving the Atenza for several years. The coolant is added at the expansion tank in the engine compartment, which is located near the headlight side and marked with a cooling symbol - very easy to find. Don't touch the radiator cap randomly as opening it incorrectly can be dangerous. It's recommended to operate when the engine is cold. Open the cap and pour in the matching fluid slowly, being careful not to overfill. Daily checks are simple - just glance at the fluid level. If it's below the MIN mark, top it up a bit to prevent issues. The coolant protects the system and prevents corrosion. Using the original brand is safer for peace of mind. Regular maintenance means fewer troubles.
