Question about 1997 Chevrolet K1500
Have the thermostat pressure tested at a parts store like auto zone or schucks if it's bad replace it. also buy a infa red heat temp gun about $30.00 use it to check the catalytic converter to see if its working, put a vacuum Gage on the intake and see if you have 18 HG in of vacuum if not your exhaust is plugged, also did you put the thermostat in right? also try a new thermostat I have had as many as three bad ones in a row, so buy a stant high performance thermostat to replace it with also what was wrong with the old engine? did it overheat to? also check that there are no bugs covering the ac condenser not allowing it to not cool, and dose it have a transmisson cooler in the radiator or do you have one mounted on the outside, if it's in the radiator you may have a transmission problem causing the problem, there are many more things to check but the infrared test gun will help you pinpoint the problem better than me just guessing without more detailed information. A bad cap will cause the water to boil if it is not pressureized and if there is no antifreeze it will boil also. and it is way to hot you may have air buble in the engine or a blocked raditor hose two, the other guys were correct to so I am not posting there suggestions again.
