radiotar hose hard

[winky]

heater core by pass is just where instead of running coolant threw the heater core you run the hose straight from the engine to the radiator

If it's 'steaming' from around the hose connection to the t-stat housing, check the hose clamps.  The aluminum water outlets have a tendency to corrode and build aluminum salt between the rubber and the housing, causing seepage.  Hot coolant vapor on a cold day may condense and appear to be steam.  Are you sure it's not just a leak, or is it blowing out?

The steam is coming out the other side of the radiator where the hose is connected to the thermostat.

[winky]

ok is it coming from between the hose and the radiator snout or out of the radiator itself?

[ChevyRay07]

Its blowing out cause there's no antifreeze coming out from there it's dry, and it seems to be coming out from between.

[winky]

there isnt any coolant in the upper hose?

[winky]

probably the same thing bd is talking about. there is probably crud built up in that connection. i would take the hose off inspect it for any damage clean the inside of it and also clean the radiator snout and put it back on. you should have coolant in the upper hose though

[ChevyRay07]

Yeah there is. When I changed the thermostat theres coolant there. So it may just be that's it has crud and needs to be cleaned out and put back on tightly. Also my radiator cap has a safety and I pull up it releases all the pressure so is that normal

Is the radiator full of coolant right up to the cap?

If you find a lot of crud built up on the thermostat housing then replace it along with a new upper hose and clamps.

Releasing pressure when you lift the radiator cap safety is normal.

[ChevyRay07]

Yeah I changed the thermostat already and it didn't have crud around the thermostat housin and yes the radiator is full to the cap

[winky]

id say check where the hose connects to the radiator  sounds like thats the best choice with the info you have given

[ChevyRay07]

Yes I'll check on that in the morning and I also wanted to see if ypu know anything about the break system?

Question......Why would someone Bypass there heater core???

Question......Why would someone Bypass there heater core??? 

leaking heater core or if one of the lines bust you can use the other to connect the intake to radiator to get you by. usually some one is in a pinch when they by pass is and they just never hook it up (mine was by passed for about a year due to it being clogged just didnt want to mess with it when it was 90 degrees out)

Auh...Good point!! I'm thinking next time I should Think, before I ask!!
