1998 Ford F150

Asked by GuruNVZLM Oct 20, 2019 at 06:19 PM about the 1998 Ford F-150 Lariat 4WD Extended Cab LB

Question type: General

When I start my 98 f150 in the morning it runs fine but the
heat blows cold. After about a mile or 2 the oil light pops
on, the heat kicks out hot and the truck starts to run
rough. I always pull over and turn it off for a second then
turn it back on. It runs fine for the rest of the day. This only
happens in the morning. Has any experienced mechanic
seen this issue before? I don't really care for all the
guessing and speculation.

Guessing and speculation are all you will get when we can't see the car and do a diagnosis and have to go off the limited information you provided. I would suspect the coolant level is low and that you need to purge air out of the cooling system.

I took it to Auto Zone. They plugged it up and gave me the print out. It recommended a PCV Valve and hose replacement. My truck is still doing the same thing. But I changed my radiator myself so there may be air in my cooling system.
