My son's Rodeo occasionally ran hot so he replaced the thermostat. Now it runs hot every time he starts it and drives a mile or two. Will a pressure test show what the problem is? Could it be the water pump?

A pressure test will help you find a leak, that's it. If the engine is overheating there can be several reasons. It may have an air bubble in the cooling system from when your son replaced the thermostat, the radiator fan may be broken, the water pump could be bad or several other things.
Best to not drive this if it is overheating, you will damage the engine. Have it towed to a shop and get it looked at by a professional, don't let him learn the hard way when it comes to a potentially expensive repair like this.
My Isuzu Rodeo is in the shop all torn apart waiting on a part. My mechanic is having a hard time dealing with the Isuzu manufactor getting a silly rubber fitting that seals a pipe going into the back side of the thermostat. The fitting is kind of the shape of a o-ring but fatter & flatter. Do you know of a site where we might find this rubber fitting?
