View Full Version : Chev junk

11-26-2013, 09:06 PM
Ive got a 2000 Chev 1 ton with a 454 I use for a service /tool truck.
It usually goes and runs OK everyday but lately its giving me some issues.
I leave it out west at a job site.

Every morning when we start it up it gets hot, guage goes right over.
Shut it off and leave it for 10 minutes and its Ok.

Its like something is freezing (its been -10 and colder) and after it gets hot it thaws out.
Its good all the rest of the day but will get hot again tomorrow morning.

Its got lots of antifreeze , a 6 month old rad and a waterpump in the last year.

Any ideas?

Sticky thermostat maybe test the anti freeze with a hydrometer
Might look green but not for low enough temp
I did it grabbed premix by mistake and mixed it 50 50
Started overheating on way to Prince George rad was freezing on hiway stop and it would thaw out figured it out after putting cardboard over grill and blocked
The cold air it quit over heating was only good to -15 when we tested it

I started it up this morning and it heated right up. I drove it 1 km to job site and shut it off.
Got in it tonight and drove it 50 kms, everything worked good.
Lots of heat coming out of heater and guage was only up 1/4 way.
Ill change thermostat soon as I get it home.
