ASE A1 Engine Repair Workbook — Lubrication & Cooling Systems | 53 Questions, Quiz with Key | Free Course on YouTube

Lubrication and Cooling Systems is 18% of the ASE A1 Engine Repair exam — and the section this workbook drills the way the test asks it: oil pressure proof, pump and relief inspection, oil service to spec, cooling pattern diagnosis, thermostat and pump, coolant service, and airflow, page by page alongside the free ASE Prep Lab Module 4 course on YouTube.

The full ASE A1 video course is FREE on YouTube — search "ASE Prep Lab" (@ASEPrepLab). Print a page, watch the lesson, and write as you go: the oil-pump circuit, the cooling-system map, and the fan and airflow layout — then prove it with the check questions built into every lesson page.
