[Healeys] Yet another mystery

Fri Oct 10 14:15:26 MDT 2025

I had my stock radiator changed to a 4-row core. The top and bottom is large enough for that. The side rails need to be modified to accept the extra width but that is not hard to do. The temperature is 190 to 200 F. It will get hotter if stopped for a long period of time.

The proper placement of the air deflectors. You said they might be wrong. My car runs hot too. New radiator, block flush. Electric push fan. Metal fan too

Do you have photo of the proper installation?

I would also suggest that you take a careful look at the baffles that are, or should be, installed forward from the sides of the radiator to the grille. If these baffles aren't correctly fitted hot air from the backside of the radiator will swirl around to the front and pass through the radiator again and thus seriously deminish its cooling ability.

Rich, 

Your comments "high speed. run of twenty miles" and "extra series of cooling tubes" may offer some clues. Fan blades flex away from the side that pushes air, in other words towards the radiator. The extra cooling tubes may have reduced the clearance between the radiator and the fan. There isn't much clearance to begin with. The combination of the two may have been enough for the fan to hit the radiator.

The other issue is what caused the overheating. At high speeds the fan has little to no effect on cooling. Unless the ambient temperature was very high and you were going up a steep hill the colling system should keep up. What was the water temperature gauge saying?

Listers,

    My BJ8 seems beleaguered with misfortune. A couple of weeks ago I noted the oil pressure gauge wildly oscillating at various speeds. It vanished two days later.

    Yesterday a high speed. run of twenty miles produce an overheating radiator with fluid spewing from the overflow tube. To my horror, I saw that the Texas cooler fan which I'd had for at least 25 years had confronted the engine side of the radiator leaving a distinct circular impression and abrasion to the tip of one of the fan blades. That radiator was rebuilt two years ago with an extra series of cooling tubes and had given no problems for at least 5000 miles. I assumed the harness which prevents the engine from sliding forward was faulty. Inspection of the underside did not support that conclusion--it looked fine to me: all bushings and nuts were in place. I ran the engine after filling the radiator and saw no evidence of recurrence of the fan nudging the radiator. I'm perplexed what to do next. Thanks for your thoughts......
