No heat in cab

Asked by GuruZKVVX Nov 14, 2017 at 05:13 PM about the 1997 Ford F-150 XLT 4WD Extended Cab SB

Question type: Maintenance & Repair

My 97 f-150 has no heat in the cab and builds
enough pressure to boil over. I replaced the
thermostat thinking it was stuck closed, all was
great for about ten days now it's the same as
before. I had no problems until the start of this
winter what's going on?

very common problem easy fix, take both heater hose lines off going into the fire wall. take your garden hose and flush it one way than reverse and flush it the other way. a couple of times this should solve the issue.

When was the last time the radiator was flushed. It is possible the radiator (and heater core) are partially clogged. This can cause overheating and poor circulation to the heater core.
