First Post !!!!!!! thanx to ppl like yall . got a possible radiator, cooling and or heater core prob. what symptoms would either cause other than temps. my turbo has been whinnin or sharp rises and falls in sound the of it. it has been bullet proofed personally. great strides better than oem. the over flow has started back leaking or pushing water!!!! not air!!!!!! remember i bulletproofed it and they had video that helped me diagnose it perfectly first time. when everybody else told me head gaskets. did that again and it is water being pushed out.i thought it was thermostat pulled it out (TEMPORALLY) its still doing it. i have no heat either. none. i was thinking it was heater core plugged. i have pulled all hoses off even pulled rad., back flushed pressured air/water thru for a while. different patterns disconnecting diferent hoses.i thought that would have got it but NOPE !!!!! the truck still has power just when i get on it or drive long distances it gets hot. cause it blowed water out nor air. water jugs on board!!!! i didnt get any debri or gunk out of system neither than i could see. its like there is a restriction some where. before i start buying just wanted to narrow it down plz.

you need to find out what the coolant temps and the oil temps are they should be no more than 15 deg difference with the oil being hotter. You will need a scanner or a monitor soloution for this. You need the sensor readings.

The difference is the delta which should be no more than 15 degF. If greater then you have restriction of the oil cooler. Coolant flows thru the oil cooler then to the egr cooler, a restricted flow causes the eg cooler to overheat and useually rupters.

This will also eventually cause the heads to crack or blow the gasket.
