Questions worth asking before you check.
When should I check coolant level?
Our lessons explain why a cool, parked vehicle is generally the appropriate context for a visual level check. Follow your owner manual and never treat a course as a substitute for its instructions.
Can I open a hot coolant system?
No. A hot cooling system may be pressurized. Wait for the vehicle to cool and follow the manufacturer’s warnings; seek professional assistance if you are unsure.
Do your courses diagnose leaks?
No. They teach observation and documentation. Persistent level changes, wet areas, residue, or overheating deserve qualified inspection.
How do I know which coolant to use?
Use the owner manual or manufacturer-approved information. Compatibility matters, and guessing from color alone is not reliable.
What is Fallows?
Fallows is your saved-course list. Select Save to Fallows in the catalog and revisit those items later from the Fallows page.
Can I study on a phone?
Yes. The interface is designed for readable mobile study, short lessons, and calm reference during planning.
Are the courses a replacement for a technician?
No. They provide general education and do not replace professional service, repairs, or vehicle-specific guidance.
How can I ask about course fit?
Use the contact form with your goals and context. We will help you choose an appropriate starting point without making repair promises.
