Re: Costant overheating 2001 sante fe
Hii!!!! have you change the water pump?? ok some water pumps have the propeler in oposite direccion get one o just call to the dealer about this tipe of water pump.make sure when you call have ready the engine size. model year . and date factory made

could be blocked radiator , head gasket, faulty fan hub if not electric
have a compression test done to eliminate head gasket and/or cracked head
if the overheating occurs at lights or in slow traffic then replace the fan hub
have a radiator shop check the flow rate of the radiator to check for blocked cores.
low water in the cooling system--check at radiator cap for full radiator
blocked radiator cores --have a flow test done by a radiator shop
corroded fins on the radiator cores --replace radiator
faulty thermostat---check thermostat operation /replace if necessary
air lock in cooling system---have the air bled out
have a compression test done to check for head gasket/cracked head
check the ac compressor mounting bolts for tight the reasoning is that when the ac is off ,the drive belt is relatively loose as the pulley is just an idler but when you engage the ac clutch the belt tightens to drive the compressor and holds the compressor tight against the engine
over heating can be fro head gasket/cracked head---compression test
partially or blocked radiator--replace
low coolant level--check at radiator cap and fill
bad radiator cap--replace
thermostat fault-- check or replace
air lock in coolant system--- bleed air oit
transmission oil overheating putting too much heat in the radiator from the oil cooler (auto trans.)
failed cat converter blocking exhaust--replace
timing --check adjustment
Is there anyway to remove the section of hose that is blocked and replace it heater hose? I'm thinking if you can replace the section that is blocked them it should allow coolant to pass through all hoses therefore giving you the heat your after!! I've also had goodluck searching u tube for answers and in most cases comes with a detailed video goodluck in your mission for heat!!
have a compression test done to check head gasket and cracked head/s. Flushing a radiator is a waste of time as blocked cores will not clear so have a flow test done on the radiator to gauge the number of blocked cores. Check the fins condition on the cores . If you have a viscous fan hub on the fan then replace it ( indications are that it overheats at lights ,when going slow or high rpms going slow but cools down when moving at speed). Check timing and air/fuel ratio as lean fuel mixture will cause overheating Check that the bottom radiator hose is not collapsing under high rpm blocking off the water flow.
have a compression test done to determine gasket or cracked head. Have a flow test done on the radiator as the cores may be blocked . If automatic check the operating temperature of the transmission oil as if it is excessive then that extra heat has to be cooled by the radiator as well. Run fault codes to check for air/fuel mixture ratio as ,lean conditions will cause over heat. Check that the fins on the radiator cores are in good condition and not crumbling off.
have a compression test done to check for head gasket or cracks . Have a flow test done on the radiator to check for blocked cores . Water pumps seldom cause overheating unless you have the wrong size pulley fitted.
have a compression test done to determine head gasket or cracked head . Check that the fan is operational . IF viscous fan hub and the over heating occurs at idle at lights etc the replace the viscous hub. Have the radiator flow tested for blocked cores and if blocked replace it as flushing is a waste of time . Check hoses and if the hose is soft and enlarged past the clamps then replace them. Have the thermostat removed and checked for correct operation
If it was over heating before the thermostat was replaced you may have a problem with blocked cores in the radiator. Several tests to do to isolate the fault. Have a coolant a pressure test done to determine if any leaks. Have a compression test done to check for head gasket and cracked head. have a flow test done on the radiator to check for blocked cores. Check that the thermostat was installed correctly ( right way up) Check that the fan is coming on and if viscous fan hub then check that the hub is operational ( Over heating at lights)
