air in coolant system (water sloshing) F150
hi guys I got a problem that's got me doin summersalts.
ive got a 2002 supercrew ,322000 km
heres my issue and what ive done
back in October intake gasket was replaced
everything fine till it got cooler in november
I could here air at the heatercore,(water sloshing around)
truck overheats ,pull over shut truck off,head safety sensor kicks in,
everything seems fine.start truck up everything is normal.this happened once a day and only when truck is cold, clear code replace thermostat.still happened
2 weeks ago I replaced rad because top hose was cold so I figured rad was plugged.i replaced reservoir cap
a couple days ago I started hearing water sloshing around again.that tells me air is getting into system.today it overheats ,I was in driveway waiting for truck to warm up.shut truck off wait 5 minutes restart everything ok.
I bled system of air ,drove around its fine again.
now it also takes about 20 Kms for me to feel heat.i fugure the heater core is plugged.
since ive replaced the rad I get less air.
I need to try and flush heater core and see if its plugged when it gets a bit warmer.
ive got no white smoke
don't have oil leaking into coolant
coolant level is not dropping
no coolant in oil
tailpipe is black so no coolant there
truck runs like a dream.
