I had a hose which carried coolant blow while I was on my way home. I didn’t notice untill I started smelling coolant, looked at temp guage and noticed it running hot and pulled over immediately. The hose that blew was located on top of engine. I obtained a replacement hose, and filled radiator. I started the truck and ran it for approx. 30 sec. When the truck was turned off it was as if there was a large amount of backpressure that expelled a lot of coolant out of the coolant reservoir. My question is: Is this normal, or the sign of something bad? I also checked the oil to see if it looked like choc milk and it did not. Oil looked fine.
