Ism running warm

[race7820000]

Ok, so I haven't had anyone look at ecm yet.

I changed the thermostat yesterday and the seal on the old one was bad so it wasemt sealing.

The truck got to the point today were it would run 200 210. Fan wouldn't cool it back down. The stop engine light would come on and I would have to pull over

I noticed the egr would cycle and when it did the coolant hoses going into the coolant resivor were putting out alot of coolant with air bubbles. But there was no pressure when u took cap off

I took the egr off pressurized the exhaust ends of it and put in a bucket of water and it's blowing air bubbles into the coolant....

Would this cause it to run hot?
