I have a 94 7.3 idi turbo. I just changed out the IP and injectors did valve cover gaskets and glow plugs. After putting everything back together and taking it for a test drive I noticed the new radiator hose I put on was stiff as a rock and spitting coolant. I assumed thermostat so replaced it and still having issues. I noticed bubbles here and there but more seems like air bleeding out of the system. After warming up the engine with cap off I don't see a lot of movement in like the t stat opening up. If I leave cap on and let it build pressure and get really hot then I see good flow. Also pulled the hoses that go to the heater core and get good flow from the hose that comes off the block but hardly anything from the hose that comes from the top of the water pump not sure which way flow is supposed to be heading... Another strange symptom is after letting the system build pressure and kick my electric fans on to cool it makes the top radiator hose collapse on itself to were its almost closed off completely. Take the radiator cap off and it goes back to normal. No coolant in oil and no oil in coolant exhaust is puffing minimal white smoke but that's because I haven't had the pump timed correctly yet please help I'm at a complete loss here
