    Is your radiator good and not plugged?Also check your fan clutch that your fan blade bolts to that it is not worn out.

  • Jack Bowser May 11, 2010

    Check the radiator part of it can be clog up. there is some good do it yourself on the market, Or you take it to a radiator shop to have it clean or gets get a new one . Tip buy distalled water when you are adding or replacing water, nothing but H2O

Is this the diesel model ? or petrol power? Never lug your diesel engine it will overheat even a new engine. Check your coolant level when engine is cooled down it may need burped. Why the head gasket change? did the head get checked for cracks and surface flatness, could be still leaking combustion pressure gases into the coolant have a test for this

    Your absolutly right a garden hose radiator flush out won't clean the tubes out it needs chemical help. i reccomend a chemical descaler from a reputable supplier like Donaldson Filtration use as per the instructions. When descale flushed out replenish with premix coolant. Is your muffler clear i have experienced blocked muffler on small automotive diesels they lose power and the exhaust manifold will show signs of running very hot, loosing studs and discoloured. Note the muffler blocks up with dry powdered soot and the perforated pipe sections inside completly close over .

What's chances that the temperature gauge or sender itself is wrong?
Is the heat exceptionally hot? What temperature is the heater dicharge when the gauge reads 260?
I think that the sender is not expensive, try that. An auto parts store could get you an inexpensive dial gauge that you might be able to install in place of the sender.

It sounds like the cylinder head gasket is leaking internally, forcing coolant into the combustion chamber and getting burnt off through the exhaust. Check the tailpipe for excessive white smoke while the car is running.

2002 malibu runs hot.


Sounds like you have a faulty head gasket or maybe a cracked head.This can cause overheating and the check engine light to come on.The code for the o2 sensor is probably caused by coolant getting into the exhaust system and coating the sensor.The coolant fan may work but it cannot remove enough heat from the rad to make the engine cool off.Try some engine coolant stop leak to see if it will help.This maybe only a temperary fix.Let me know if you need more.MOE

It loses power on acceleration and serious loss of power on hills


sounds like a clogged fuel filter. you need to have the engine pressure checked for leaks, you can rent the pressure checker at autozone, it connects to ur radiator and u pump pressure into the cooling system if u find water leaking around the head u know u have a blown head gasket. if ok then check the cylinder compression should beable to rent this also. it screws into the spark plug holes has a gauge on it. alternator problem w/ the light is probaly you need to tighten the belt.hope this helps!!!

It sounds like you have a partial blockage in the cooling system. If liquid gasket material was used with the pump an or thermostat replacement some of this material may be in the coolant path. Other things to consider; your thermostat is the wrong temperature, you got a bad water pump. Take the radiator off and start the car when it is cold. Let it idle and watch to see if coolant begins to circulate after the engine reaches the operating temperature to be sure the thermostat is working correctly as well as the pump.

Temp Gauge Creeps Up


I would take it in and have then do a block test to be sure you don't have a head gasket issue, Does the coolant get low after a few days or so. This could be a sign.
Also sometimes its hard to get all the air out when you drain the coolant and fill up. Be sure the coolant bottle is up to the ok line..
And if everthing checks out ok then maybe your ready for a water pump. The fan blades on them tend to wear down then they dont pump water too good.
Lastley your radiator could be clogged.
Best bet is to go to a shop and pay the 50 bucks give or take and let them tell you whats wrong

2000 Elantra Overheating


First when vehicle is cold like in the morning check and make sure that the vehicle has enough coolant/ antifreeze in radiator and reservoir. If coolant is need use a 50/50 mixture of water and antifreeze. You will need some time to do this let car run at idle until the temp guage is in the middle NOT+ normal operating temperature. At this point if the thermostat should be in the open position. Let vehicle run and check to make sure that radiator fan comes on. This should come on when guage is about midway/half way. If temperature rises above half going to h/hot and fan doesn't come on, you either have a BAD FAN BAD FAN SWITCH BAD FAN RELAY OR BLOWN FAN SWITCH FUSE. You will need to check all of the following I will help if its needed. If fan comes on and doesn't go off and vehicle continues to get hot even with fan running. Feel radiator hoses and see if the lower radiator hose is cool/cold. If it is you have thermostat that stuck closed. Replace thermostat and fix problem. If all the above is good and vehicle continues to over heat. THE BAD NEW IS THAT YOU MAY HAVE A BLOWN HEAD GASKET /CRACKED HEAD /BROKEN WATER JACKET. Basically you will need a HEAD JOB at least a head gasket. ONe tell tail sign of this is oil looking like milkshake/chocolate milk-a creamish while residue in oil or antifreeze. Contact if you need hel0p. Good Luck and thanks for using FIX YA
