Did it fix the problem?

Unfortunately no. We will be opening the water passages in the block to see if it solves

I saw the pics you posted of the larger fan. Not sure you are getting the proper air flow with it being too large for the opening you are trying to push air to. Just asking to make sure, did you purchase a pusher fan? The fan I recommend was around $85 and reversible.

I just bought this cheap chinese fan for the condenser locally in Panama. Ill follow your recomendation.

Is it pushing or pulling air? If it’s not pushing air through the radiator you’re fighting the engine fan trying to pull air. Make sense.

What about removing the water passages to see if there is any built up inside? I really prefer keeping the new fan clutch we recently installed instead of going with the dual electric fan configuration. Car only runs into heat issues during stop-and-go traffic jams after 10 to 15 minutes.

Never answered the question if the front fan was pushing air or pulling. Which direction is the electric fan blowing? Hard to give help if you don’t respond to the questions asked.

Havent checked this yet. Ill need to crank the engine and start the Air conditioner. I will revert.

If you have it blowing the wrong way it’s going to make a huge difference. Check that before anything else.

Jumping in VERY late. I had a similar issue to this and changing to this fanclutch fixed it since it grabs harder than the standard Aisin one.

Can you describe you car symptoms? I bought this fan clutch and it aint solving the hesitation once the temp hits 3/4

The symptoms are it was over heating. You never went back and reversed the fan blade and polarity to push air through the radiator.
