GROUNDWORK CARE PACK — Mazda3: follow coolant loss through a service recheck Pack: mazda-cooling-handoff | Version 2.0.0 Create a cold-level and addition history, carry it into a service request, then preserve the post-work cold reading and any remaining heat symptoms. Source page: https://csl-12-auto-repair.pages.dev/packs/mazda-cooling-handoff/ Vehicle: mazda3-2017-us ORDERED STAGES 1. Establish the loss history Compare cold F/L observations and actual coolant additions without opening the cooling system. Record: A sequence of cold readings, additions, accessible wetness and temperature symptoms. Date: __________ | Observation / outcome: __________ [ ] Check repeated coolant loss — https://csl-12-auto-repair.pages.dev/tasks/mazda-coolant-loss/ 2. Prepare the specific inspection request Identify empty reservoir, repeated additions or heat symptoms that need professional assessment. Record: A request describing recurrence and unanswered questions, with any actual service recorded separately. Date: __________ | Observation / outcome: __________ [ ] Check repeated coolant loss — https://csl-12-auto-repair.pages.dev/tasks/mazda-coolant-loss/ 3. Recheck after the recorded work Observe only after full cooling with the fan stopped, and keep unresolved heat symptoms visible. Record: Post-service cold F/L reading and a stable/recurring/unknown follow-up result. Date: __________ | Observation / outcome: __________ [ ] Recheck coolant after service — https://csl-12-auto-repair.pages.dev/tasks/mazda-coolant-recheck/ FINAL REVIEW Every compared reservoir reading is cold and caps stay closed. An empty reservoir or frequent additions is directed to service. A normal post-service level cannot close continuing overheating. HANDOFF NOTES List the known cold-level and addition history.: __________ Record the service request and actual work, when available.: __________ Record the later cold result, any heat symptoms and the next service/recheck action.: __________ COMPLETE TASK PLANS GROUNDWORK — Check repeated coolant loss Task: mazda-coolant-loss | Content version 2.0.0 Source page: https://csl-12-auto-repair.pages.dev/tasks/mazda-coolant-loss/ MODEL / APPLICABILITY [{"modelId":"mazda3-2017-us","market":"US","year":2017,"engine":"SKYACTIV-G 2.0 / 2.5 gasoline","configurations":["all","4-door","5-door","type-b-audio"]}] EXCLUSIONS Other model years and markets; imported Axela or diesel models; modified or aftermarket components with a different procedure.

OBSERVE & RECORD Observation date: __________ Vehicle / equipment confirmed: __________ Write cold readings and additions in sequence; keep hot readings separate and preserve any heat symptom. Cold reservoir level: __________ | Choices: Between F/L; At or near L; Empty; Above F; Unreadable Previous cold observations: __________ Dates of coolant additions or unknown history: __________ Accessible wetness and temperature symptoms: __________ Overheating, temperature warning or steam history: __________ | Choices: No heat symptom observed; Overheating, temperature warning or steam occurred; History unknown Before care: __________ STEPS 1. [ ] Switch ignition off, allow the engine and radiator to cool, and verify the cooling fan is stopped before approaching the area. https://www.mazdausa.com/siteassets/global-resources/vehicle-resources/owner-manuals/2017/mazda3/2017-mazda3-owners-manual.pdf#page=440 | PDF page 440 2. [ ] Read the reservoir from outside. The manual’s cold-engine reference is between F and L; leave both cooling-system caps closed. https://www.mazdausa.com/siteassets/global-resources/vehicle-resources/owner-manuals/2017/mazda3/2017-mazda3-owners-manual.pdf#page=441 | PDF page 441 3. [ ] Compare with previous cold-level observations, if you have them. Do not compare a hot reading with a cold one. https://www.mazdausa.com/siteassets/global-resources/vehicle-resources/owner-manuals/2017/mazda3/2017-mazda3-owners-manual.pdf#page=441 | PDF page 441 4. [ ] An empty reservoir or frequent need for new coolant calls for an Authorized Mazda Dealer. A low reading alone cannot identify a hose, pump or gasket failure. https://www.mazdausa.com/siteassets/global-resources/vehicle-resources/owner-manuals/2017/mazda3/2017-mazda3-owners-manual.pdf#page=441 | PDF page 441 5. [ ] Record level, recurrence and any visible wetness for service. If coolant is required, use the specific manual and FL22 marking as applicable, not a guessed universal mixture. https://www.mazdausa.com/siteassets/global-resources/vehicle-resources/owner-manuals/2017/mazda3/2017-mazda3-owners-manual.pdf#page=441 | PDF page 441 6. [ ] Write cold readings and additions in sequence; keep hot readings separate and preserve any heat symptom. https://www.mazdausa.com/siteassets/global-resources/vehicle-resources/owner-manuals/2017/mazda3/2017-mazda3-owners-manual.pdf#page=441 | PDF page 441 DECISION CHECKS Is the engine cool, fan stopped and reservoir readable without opening either cap? Yes — ready for this check → Continue with the steps, stopping if the real component differs from the manual. Not yet / not sure → Preparation saved. Return when the condition is confirmed; leave the vehicle untouched. Empty reservoir, steam, overheating or visible leakage → Empty / low reservoir, recurring need, overheating or leak: arrange cooling-system inspection. What do the level and history show? Cold level between F and L and no repeated loss observed → Has overheating, a temperature warning, steam or repeated coolant loss occurred, even though the level may look normal? Empty / low reservoir, recurring need, overheating or leak: arrange cooling-system inspection. → Empty / low reservoir, recurring need, overheating or leak: arrange cooling-system inspection. I have only prepared the plan → Plan prepared; no physical maintenance result recorded. Is there no repeated need for coolant and no heat or leakage symptom accompanying the cold reading? Normal cold observation with no recurring loss or heat symptom → Cold level between F and L and no repeated loss observed The observation or repeat check is still incomplete → Plan prepared; no physical maintenance result recorded. Repeat loss, empty reservoir, wetness or heat symptom → Empty / low reservoir, recurring need, overheating or leak: arrange cooling-system inspection. Has overheating, a temperature warning, steam or repeated coolant loss occurred, even though the level may look normal? Yes — heat symptoms or repeated loss have occurred → Empty / low reservoir, recurring need, overheating or leak: arrange cooling-system inspection. No heat symptom or repeated loss observed → Is there no repeated need for coolant and no heat or leakage symptom accompanying the cold reading? The earlier symptoms or history are unknown → Plan prepared; no physical maintenance result recorded. RECHECK Does another fully cold observation show renewed loss, or is more coolant being requested after the previous service? After care: __________ Retest: not checked / improved / unchanged / worse If an earlier condition changes, reassess the later checks and result. RESULT CHECK What do the level and history show? Cold level between F and L and no repeated loss observed Record only the result you actually observed. A saved web checklist is not confirmation that a vehicle has been repaired. Is there no repeated need for coolant and no heat or leakage symptom accompanying the cold reading? Does another fully cold observation show renewed loss, or is more coolant being requested after the previous service? STOP CONDITIONS Empty reservoir, steam, overheating or visible leakage Empty / low reservoir, recurring need, overheating or leak: arrange cooling-system inspection. A part, label, connector or fastener differs from the cited manual; access requires raising the vehicle; you cannot identify the correct component. SERVICE HANDOFF Take the recorded observations, their dates and any actual work history to the service provider. Empty / low reservoir, recurring need, overheating or leak: arrange cooling-system inspection.
