I've been looking at this on Identifix, not too much of a progress. I know you've got quite some skills at coolant replacement by now, but I noticed a couple of steps that I don't think you mentioned before. Have you given the motor some gas as per the manual?
A. Refill the coolant from the cooling system filler neck until it is close to the top of thecooling system filler neck.
Refill the coolant into the coolant reserve tank up to the F mark on the tank.
Install the cooling system cap.
B. Start the engine and warm up the engine by idling.
C. After the engine warms up, perform the following steps. At this time, be careful of the coolanttemperature to prevent overheating. Run the engine at approx. 2,500 rpm for 5 minutes.
D. Run the engine at approx. 3,000 rpm for 5 seconds, then idle.
Repeat step (2) several times.
E. Stop the engine, and inspect the coolant level after the coolant temperature decreases. If it is LOW, REPEAT STEPS A-D.
