thermostat stuck bypass hose clogged?

 

I haven't got the car up to full operating temp to see if the thermo is bad. Where is the bypass hose at? And how would I go about uncloging it?

 

it means the thermostat is staying closed. You didn't put it in backwards did you?

The pellet and spring need to go towards the engine. Also make sure the arrow and air bleed hole are at the top.

 

No I didnt put it in backwards. Spring side towards in the block. I'm testing the thermostat now with hot water

 

dont you have a hose on the pipe sticking out of the water pump thats ajso a by pass

 

Yeah but I don't know how I'd unclog it, thermostat is good, just tested it

Edit I can blow through the hose that runs to the firewall, so I don't think it's clogged

 

im not saying its clogged you got the top hose off right put the garden hose in the top rad hose with radcap on see if water comes out of thermostat mount on block

 

Well I got the gasket to seal, I had felpro sheet gasket laying around so I traced it out and made one, stuck the two together with rtv and it holds. Jeep runs like a champ. I wanted to thank everybody on here that has helped me out!

 

Update.

Serpentine belt squeaks badly and jeep starts to overheat. Heat is blowing ice cold. The upper and lower rad hoses are hot like usual, the two hoses that run to the heater core are swollen, but one of the hoses are warm and the other cold. I'm thinking the heater core is clogged. then fluid starts to seep out of the rad cap.Any suggestions? Thanks!

 

heater core being plugged will not cause truck to over heat did you run it until the thermostat open then fill with water and sound like rad cap is no good not holding pressure 210 degrees is normal , belt loose causing sqyeeking, is radiator hot all around top to bottom

 

But what I don't understand is that it held pressure today when I drove it around town.

 

ok whenyou were driving you were pushing air thru the radiator when idleing you not with motor off soin the fan if it spins freely when hot the clutch on it is no good it will spin freely when cold should not spin as free when hot

 

Could the thermostat be bad?

 

you checked it if it runs good and normal temp when driving but does not when sitting its an air flo prob thr radiator cap should not leak water out

 

I also didn't let it deliberately overheat, I shut it down when it reached 215 and that's when coolant started to seep out the rad cap
