thermostat problem?
If my thermostat was defective and was staying open would this possibly be the cause of my truck taking a very long time to warm up. I changed the antifreeze first last weekend and this didn't help. I didn't have enough time to flush the system or change the thermostat. The heat is warm-hot after my truck gets to temp. Also my heat only works on high is this the switch or possible something else. This is a 98 f150 4.6. Thanks

sounds like a thermostat- remove it-check it in hot water for proper function. you will need a good thermeometer. replace if defective.after taking care of the basics -check heater operation.
