Odd problem with this car overheating any help would be much appreciated!
We have had our 2003 Tiburon GT 2.7L for about 8 years in total started with my brother he never changed the spark plugs and moved the air filter down infront of the left front tire. We recently changed the spark plugs which we noticed a big increase in power sense the 3 of the spark plugs were barely igniting anyways this is were the problem starts, after the spark plugs we drove to a place about an hour and 30 minutes away and the car got super hot the A/C got hot and humid. It was also 105 degrees outside but the coolant was boiling when made it back home and tried to diagnose it, we replaced the thermostat nothing, we flushed the car multiple times nothing, One thing we did notice after flushing is that after flushing that milky rusty residue started coming up after each flush we figured it was the radiator because the radiator is super messed up super rusted so we figured that it may need a new radiator and A/C condenser but we are at a loss for what may be wrong we thought about the water pump but it seems to be pumping fine but again it is super old another idea which we have not checked would be the heater core, Head gasket and haven't checked the oil to make sure anything is cracked and crossing the coolant and liquid. One thing that was off though was we did a coolant flush and the milky rusty liquid came up the car got super hot pretty quick but cooled down decently quick we ran the car on water for awhile and the car seemed to run hotter on the coolant than water but the A/C was way cooler with the coolant. It’s something super odd we cannot think of anything else but again maybe we are missing something. Any help will be much appreciated!
