Before changing radiator is check thermostat which may be sticking. A lot cheaper and easier to replace. Can remove and put in pan on kitchen stove in water bring to boil to see if therm will open or simply buy new one. There cheap enough. Also I'd check hoses as years of use they do buildup gunk especially if uv used any type of bars leak/ etc. No luck with those radiator. Easy to change should be 4-6 bolts. Can buy a Haynes or Chilton book which I usually do for every car I own or can get screwed bringing to garage. Gl

SOURCE: AC works, Heater not working, 2003 Hyundai Accent.

Check the coolant level, do this with a cold engine. Or if you have recently used it. let it cool down for about 25 minutes before removing the radiator cap. if it is low, refill with coolant. If it does not, check your thermostat. Or better yet replace your thermostat. Be sure to get the right one . the same degrees as your old one. Just ask the teller to give you one for your engine size and car Model.And year.See where the radiator cap is. Then drain some coolant to where it will not spill from the radiator cap. Remove the hose nearest the radiator cap and you will get to the thermostat housing. Remove the housing and note how the thermostat is placed. Take of the thermostat housing and the old thermostat. Clean the housing and around the hole where the thermostat goes of any deposits. Get some grease and cover the new gasket with grease on the housing to hold it in place. replace the New thermostat and make sure it is flush with the engine and the housing. If it is off , you could break the housing upon tightening the housing.replace the hose and refill with coolant slowly to eliminate any air spaces.. Also check the coolant reservoir and fill it to the indicator line. Restart the car and chek for any leaks. Then check the heater after the engine heats up. If that does not do the job it could be the temperature sensor or the heater core.The heater core will take more time to check and clean or replace.

SOURCE: how do you remove radio from hyundai accent 1998

You have to take out the ash tray, and remove those two screws, then pop out the center dash trim. Careful, though, you have to take out a lot of the wiring inside of your center dash trim in order to pull it out for enough room to move the radio in and out. I'm doing this right now, actually..

once you pop the hood, there should be a cover behind the light housing that you twist to open the backing.. inside the housing will be a spring lever that secures the bulb down... unhook the spring and disconnect the harness connecting to the bulb...

SOURCE: Antifreeze for a 2003 Hyundai Accent

hi as this vehicle takes 6.5ltrs of liquid in the cooling system ( 1.6 16v based on ) as you did not give the engine size, but, 3.5ltrs of coolant is needed as it should be 50/50 depending on where you are and the temperature it has to deal with, warmer countries only need 30/70 That's 30 coolant to 70 water, but, if you are in a colder country it would be 80/20 that's 80 coolant to 20 water...and any standard coolant is ok no need for a specific one hope this helps please vote thanks

How do you put radiator in 1999 hyandai accent

1) Drain radiator by removing cap, and bottom radiator drain bung or bottom hose.
2) Remove top hose.
3) Disconnect the radiator fan's wiring and any temperature sensor wiring if fitted.
4) Remove radiator retaining clasps
5) Disconnect radiator bottom hose.
6) If fitted with an auto box, then remove automatic gearbox oil pipes (Underside)(you might wat to clasp these so they don't leak oil everywhere)
7) Remove radiator expansion bottle feed pipe from top of radiator.
8) Ease out the radiator. If the radiator fan is getting stuck or caught up, then drop the radiator back down and remove the fan first after disconnecting from the radiator body.
9) With new and old radiator placed side by side on a soft surface, change across any components from the old radiator, which didn't come with the new one. These may or may not include such things as: cap, fan retaining screws or clips, bottom radiator seating rubbers, rubber fan shrouding, temperature sensor, top and bottom rubber hoses.
10) Rebuild by reversing the above instructions. Apply silicone pipe sealant to top and bottom hose locations. Make sure you clean and/or replace any heavily corroded metal pipes which connect to the radiator. (Now is also a good opportunity to replace the thermostat to be on the safe side)

11) Fill system with a fresh 50/50 water/antifreeze mix, flush out and refill expansion bottle. Just before you refill the system, turn the interior heater setting up to maximum heat, but do not start the vehicle.
12) Top radiator up to max. Gently massage the top radiator hose to help eliminate air from the system.
13) Once filled, start the car. Pay attention to the temperature. Keep topping up the radiator as bubbles come around the system and the coolant level drops. At the point no more bubbles appear, close off the radiator with the cap. Allow the engine to reach normal operating temperature. If the weather is cold you may want to hold the engine at around 2,500 revolutions to help build heat faster. Keep it running until the radiator fan kicks in, then let it idle for a couple of minutes.
14) Stop the engine and let it cool.
15) Once cool, open the radiator cap and top up again if level is low.

16) Road-test the vehicle. After returning check again for any leaks.


Running the car for the first few days after radiator replacement, check the radiator level and expansion bottle level every day for the first two or three days. This level may drop slightly as any trapped air pockets are pushed out while running. Also, it is possible that any small leaks may begin after adding fresh anti-freeze to the system. If you begin loosing fluid over these first few days, then re-inspect your work and run a cooling system pressure test.

Engine warms well, heater fan blowing well, but very little heat comes into cab

It could be one of two things.
1. Bad thermostat. Your thermostat is pobably not opening when the engine warms up. Install a new thermostat and you should be OUT OF THE COLD. If not,
2. Your heating core and radiator is probably clogged. One way to solve this is. Flush out your radiator with radiator flush kit. Pease read your owners manual, (YOU NEED TO USE A SPECIAL TYPE OF ANTI FREEZE). If you use the the green color Presotne anti freeze, It will gradually corrode through the linings of your radiator. And the green color prestone anti freeze will blow out the radiator. So read your owners malual ( I beleive it says you have to use Dextron Anti Freeze ( Pink Color).. Replace your thermostat and flush out your radiator. Then refill your radiator with dextron anti freeze. Also make sure the anti freeze resivor is filled to the proper level.. Once you do all of this, YOU DEFFINITLY WILL BE IN HEAT.. YOU CAN DO THIS YOUR SELF ( iT WOULD TAKE ME NO MORE THAN 1 TO 2 HOURSFOR ME TO DO THIS IN MY DRIVEWAY) OR YOU CAN HAVE THIS DONE AT ANY QUICK LUBE LOCATIONS... HAPPY MOTORING

My 2003 hyundai accent is over heating I replaced the thermostat the belts are fine Im not sure what else it could be

If it only overheats while stopped or when driving slowly then check to see if your radiator fan is coming on. If not check the radiator fan fuse, temperature switch, relay, and the fan motor itself.

If it is consuming radiator coolant or is blowing steam out of the tailpipe then consider a blown head gasket as your problem. The engine oil may or may not look milky in color if the head gasket is leaking.

did you install the thermostat pointing in the correct direction? Is the radiator cap in good shape? Check for correct coolant level. The radiator will continue to draw in coolant from the reservior for many heat cool cycles after it has been opened.

And lastly could the temp gauge be reading high? Possible temperature sensor.

Engine is over heating but there is plenty of anti-freeze in it

check the thermostat by taking the radiator cap off then start the car ,after the car comes to temp. the thermostat should open.you will be able to see this for the anti-freeze will start flowing(it will take a few minutes for the car to warm up ,be patient).if it doesnt and car starts to over heat thremo is bad.another possability is the radiator its self,depending on the conditions at where you live ,per say in the country with gravel roads can plug the radiator pores,go to car wash and manualy wash the front of the radiator to get it clean now it can breath(have air flow pass through it.that is how the car cools itself down.one last thing ,check the oil,if it is low that can help the car overheat.

2003 Hyundai Elantra: Air is only heated when the gas pedal is pressed (while on the highway the air becomes hot). When the pedal is released (slowing down/stopping) the air cools down to cold.

I had same issue. Turns out it was low on anti-freeze in the radiator. I added fluid and now have lots of heat!! Be sure to also add radiator fluid to the overflow tank too.
