Las vegas, Nevada (hot city right now)
Trying to keep my camaro from heating up.
1988 camaro sport, 305 TBI automatic
New radiator, thermostat, coolant, has been flushed,
new oil, temp sensor etc. Have tried different thermostats
also, but my baby still runs way too hot. Timing good,
plugs are new on and on. Any help is much appreciated!!

Both fans running?

Unless his is different than my TBI, there is only 1 fan. I would ask
for the definition of too hot, as mine runs around 210-240 which is
normal. That said, if I run the AC, then it starts to rise until it
really is overheating. I have not yet been able to find out why it’s
doing this, as I have changed the radiator, all hoses, thermostat and
sending units with no change. The fan runs when it’s supposed to (comes
on at 220-240 and turns off at around 200-210 and runs any time the AC
compressor is running) and still with AC on it slowing increases in temp
until it reaches the point of overheating if I let it keep going. If I
turn off the AC, it goes pretty quickly back to normal. Oh, I went with
the highest cooling rating choice for standard/compatible radiator
available for my model. I also added an external trans oil cooler and
bypassed the one in the radiator to remove that as a source of heat. I
am thinking of an engine oil cooler next.
