91 Ford f150 4.9L inline 6 is overheated and will not start. I need help troubleshooting the problem. Any advice is most appreciated. Thanks
91 f150 4.9 inline 6. Started losing power
the other day, I checked under the hood and
noticed the hoses to the air intake had
fallen off. It had been in the shop and I
guess someone had forgotten to put it
back. I put them on and tightened them,
than drove it approx 40 miles. It overheated
and lost fluid from the cap (at least that is
where I noticed the majority of the fluid)
and took quite a bit of water to refill
radiator. I was at a rest stop so water was
my only option. After it cooled down I
cranked it and after about 10-15 min it
began to overheat again. Pulled over and
repeat. Top hose was hot to the touch.
While running it, I turned the heat on and it
started out hot but within a few minutes
started to become cool. After many times
driving and stopping to let it cool I made it
to an auto parts store and picked up some
radiator fluid and thermostat. Truck would
not start from then on. Haven't installed the
t-stat yet. Any ideas/ suggestions would be
most appreciated.
