truck is overheating
okay i just finished up repairing my truck 96 ford f150 5.0L
I replaced the engine/coolant sensor, the thermostat, water pump, new
antifreeze (right mixture) filled it up, let it run for about 3 minutes. took it
down the block, idled for a few moments with the heat on. the temp guage
with from the low position before the "n" of normal to now being between
the "r" and "m" of normal. as soon as i started to drive back to the house it
spiked in tempture to being at the "a" and "l"...i started to smell something it
didnt smell like antifreeze, but as soon as i turned off the heat the temp
guage went down to the "m" and the "r" and the smell stopped. any advice
or suggestions?
would it be something to do with the heating and cooling.....
