Why does my sportage keep overheating

goodyear are tyre mechanics
water in the oil is from a hole in the housing (aluminium timing chain cover ) behind the water pump impeller or problem head
before anything was replaced , a compression test should have been done to determine the condition of the head and head gasket
next a coolant pressure test should have been done to determine if there was a leak in the cooling system ( the housing crack would have been obvious at the test
water pumps always work if there is water for them to work in and only need replacing if there is a water leak from a hole in the housing ( seal failure ) or there is a failed bearing noise
I could suggest that you find an accredited professional service center that has experience on your make of car and get a proper diagnosis before you waste any more time and money on tire mechanics

Hello and welcome to FixYa!

If you have overheating problem, it can lead to multiple issues. You may be running on low coolant that's why the vehicle overheats. If that's the case, please add coolant and make sure that it sits on the right level, too much coolant can cause overheating too for coolant will overflow.

The vehicle may have a faulty or worn out radiator blower motor that's why it overheats. If that's the case then you will need a blower motor replacement to resolve the issue.

If the radiator is clogged with dirt and rusts this issue occurs too. The coolant doesn't flow normally on the cooling system if it's clogged. If that's the case, I strongly suggest that you have the radiator flushed to drain out dirt and rusts. If you think that the radiator served you enough then it's better to have it replaced.

Please do check the radiator hoses, If you have worn out hoses it can cause coolant leakage which can result to overheating. A tiny hole is good enough for the vehicle to overheat.

A faulty thermostat sensor can cause the issue too. If you have worn out thermostat, the fan may not trigger that's why the fan won't work when under stressed conditions. A blown radiator blower fuse can cause this issue too so I suggest that you check the radiator blower fuse and replace it when necessary. What causes the radiator blower fan fuse to blow? It's because of a failing radiator blower motor, If that's the case have the radiator blower fan motor replaced.

If the fluid in radiator doesn't circulate then it means that you have a blown head gasket or a faulty water pump. I suggest that you go for the water pump replacement first specially if you think that it's near the end of it's service life. Usually, water pops out the radiator when engine is reved (a sign of faulty water pump and possible blown head gasket).

Hope you find this information helpful enough and thank you for using FixYa! Have a good one!

compression test most likely blown head but first why did you change all this stuff if the cause was overheating then am suspecting a blown head gasket

The thermostat is the engine temp controller. All the sensors do is relay information.

Are you sure your over heating. Has anyone infrared temp tested the actual temperature.

If you are really overheating a temp gun can test differnnt areas to try to find a blockage somewhere.

You could have a clogged radiator if you used a sealer in the coolant pryor to doing the head gasket.

First, anytime a thermostat is overheated, it's ruined.

Second, if this car has electric fans, are they running when they are supposed to? If not, replace the fan control module, and/or test/replace the fan motors.

When the radiator was replaced, were you certain to purge the radiator and engine of all air before replacing the radiator cap? When you refill an emptied system, you always start the engine and watch the fill level in the radiator, refilling as necessary until you know the thermostat has opened. You need to have the heatrer controls set to full hot as well. Once the radiator is filled, put the cap in place, and fill the reservoir to the level indicated for a hot engine.

Finally, check to make sure the lower radiator hose is not collapsing while driving. While this is difficult to check (because your going down the road), just replace it when you replace the thermostat.

All of this assumes you do not have a cracked head or blown head gasket.

Most likley overheating when under load. usaully blown headgasket. also make sure fans are coming on. Out of spec timing can cause some overheating issues. Specs located on under hood label

replace radiator cap system depends on good pressure to keep from overheating

Hello, There are many things that can cause this problem. It could be anything from a blown head gasket to a water pump. If you want to eliminate the water pump, take the thermostat back out and leave out, start motor, and see if you have a good coolant flow from water pump. Also, ck your fan clutch. This won't necessarily cause it to overheat at road speed but at slow speed or idle it could. There is also the possibility that your radiator is stopped up. There is something else, although rare, I have seen happen. Check the small coolant return hose at the radiator to make sure something hasn't blocked the small plastic nipple. If this is blocked, coolant will not circulate.
Check your engine oil for any kinds of water contamination, check your plugs for water, if you have access to a coolant pressure tester, pressurize cooling system, remove spark plugs, let stand for at least an hour, then turn engine over and see if any coolant comes out. This may give you an indication that your head gasket is blown.
I hope this helps.

There seems to be an air pocket or no antifreeze in engine block. Try this method disconnect upper radiator hose and pour water directly into hose down into engine block until it full. when its filled reconnect hose and fill up radiator. as the vehicle warms up open bleeder valve on the thermostat housing and release air from system. open slowly and BE VERY CAREFUL WATER WILL BE HOT, bleed until you get a steady stream opening and cosing valve. However if all of this don't work. You may have a bad pump. Good Luck
