Default Overheating Camry

My 1994 Camry went into the garage for a distributer seal change
and several other gaskets.
Within 2 weeks of this repair, it started overheating.
I put it back into the shop as the mechanic declared it to be a worn
water pump. I paid him to replace it.
It still overheats. I refused to pay the mechanic for more work
and replaced the thermostat and cooling fan switch myself.
Flushed the radiator and refilled with coolant, not water.
Still overheats.
I let my friend take it for a test drive and he confirmed the
condition I had found to initiate the problem: A hard turn, left or
right, like at a stoplight. Otherwise it doesn't overheat.
Once the steam starts blowing, hosing water onto the radiator while
idleing for several minutes will bring the temps down.

I've run out of ideas. Anyone everheard of overheat-on-turn problems?

If the fan is on when it is overheating, you probably need
a new radiator. I can't think of anything that would be turn
related, unless the movement causes the fan to quit.
The radiator is probably about half plugged up more than likely.

I'd kind of suspect the engine is heating up while sitting to turn and
the lag till reporting shows up after the turn. You might try running
the heater on full hot while sitting to see if that keeps the system
cool. All the other usual things to consider. Blocked radiator,
inside collapsed lower radiator hose, fan, fan relays, thermostat even
though it's new, I'm assuming the water pump is driven by the timing
belt so a locked AC or power steering pump ought not affect it, blown
head gasket, probably a 100 other things also. Anything that would
cause the fan relay to shut the fan off.
Let us know what you find when you find the cause. Anyway a
radiator hose can be pinched when making a turn? Bad motor mounts or
dog bone maybe?

I'm not seeing any pinch points or evidence thereof.

I'm not sure what you mean about "inside radiator hose".

I plan to change the both visible hoses this week.

If that doesn't fix it, I'll get a radiator.

Anything interesting happen under the hood when you have a friend turn
the steering wheel all the way to the right and left (while the engine
is running, of course)?

On a 1994 you're probably overdue for a radiator anyway. On our 1996 the
plastic radiator cracked a couple of months ago (140K miles). In many
cases Toyota parts are preferred, but the Toyota radiator was about 5x
the price as the after-market.

I assume you checked to see that the electric fan is actually coming on.
