Diagnose engine cooling fan relay problem.

If your p1496 toyota estima check engine light is illuminated it s best to take it in for diagnostic testing which can feel like a hassle. Installing a radiator core with too high density too many fins and tubes per inch can restrict air flow enough to create this problem. Cooling fan relays fail when the radiator cooling fan no longer receives an electrical signal. Still the same problems.

Follow the instructions on the test of pressure to your cooling system also check for coolant leaks onto the ground from radiator area. The coolant level remains full so no cracks or leaks in the resevoir tank.
