will this unit heat a 1990 4700 international 4 door truck ? as the original heater core is missing
A: That is unknown. It would be best to compare the BTU output of the original equipment to this unit to determine. The manufacturer would have the necessary information.

My Bob Cat is cooled with oil. Can this heater take the pressure of oil cooling system
A: The manufacturer pressure tests the cores to 460 psi and holds that for 24 hrs. It was not stated if this was a test for max pressure to determine a 4:1 safety factor and a lower working pressure should be used. Check the average pressure of the oil cooling system before judging.
