1997 Hyundai Elantra - Answered Questions & Fixed issues

Check for water in the oil (gooey foam after running) - blown head gasket. Check for exhaust smelling bubbles in the radiator - blown head gasket. Otherwise heat activated fan switch (on the radiator) is not coming on soon enough or at all. No fan will overheat an engine especially if a lot of stop and go or idling on warm days.Most common is a stuck thermostat, blocking circulation. Other causes are a blocked radiator - shut a warmed engine off and feel the radiator all over - if too cool in some areas, it is possibly getting clogged up inside. If you are getting radiator antifreeze smell inside the car (fogging the windshield when the car starts in cool weather) your heater core is leaking.

Run a compression test or cylinder leak down test on the engine. You have an oil control ring or a valve seal that is failing.

Clean off leak as good as you can. You can buy a die to put in the oil, usually yellow. After driving for directed amount of time on bottle you put on the ultraviolet sunglasses that come with the kit and you can see where your leak is coming from. Might help to pin point it at least. Hope this helps https://goo.gl/Pn8V2m

Hi Pocketlock.Have you tried tuning it up? Try changing your spark plugs, wires, and change your air filter. You can also put an injector cleaner in your gas tank. (Techron or Seafoam are good products, Techron is better in my opinion). You should see a difference in engine performance. Hope this helps.

Hi the trans range switch or some times called an inhibitor switch needs replaced and have the bands adjusted for the transmission which is an external bolt with jamb nuts near the range switch after that has been performed the battery cable removed for 10 minutes to reset all adaptive learn for transmission

check the earth wire from the battery there maybe a fault with the electrics. check the earthing points and connection to the battery.clean earthing points and connections. electric faults could be anything but these are the most common things to check. also if you have a meter check the battery check its volts before starting engine and check after the battery that is fully charged should read 12.04 or a bit higher. and with engine running it should be 14.00 volts can be higher by a bit. if the battery is fully charged and lower than 12 volts it has a problem if the charging from the engine is lower the 14v then they could be a problem with the alternator. if you have a drop out while driving parts of the system will drop as the voltage has dropped below it working rate. abs is 11 volts or lower will cut this out and say its not working and so on with other devices.

new gearbox needed or band adjustment by expert

Pull the coil off and install a spark plug in the boot, then ground the plug and crank the engine you should see a spark. If not he coil may be the issue or the wiring to it or the powertrain module that controls it.

I would assume u mean shift solenoid which is inside transmission

It could be your pully is not engaging the thing your belt turns on your altenater or volt regulater or the electrical from your altinater to your battery i would replace atlinater anyway

Pull up the diagnostic trouble codes and freeze frame data to locate the area.

Did you clean where the bulb goes in might be dirty bad connection if dirty.

it mounted an the transmision case wheare the shith linkage call range sensor

There is only one way . Remove it and replace it with a new one. after you get it out check if it is rusted if so replace the others , other wise they will leak later on . fill with new coolant to stop future trouble. If you search around you may find some brass plugs they wont rust out.

Use stop leak or better, replace it.

Check the fuse. If its okay there may be another fuse behind the unit (inline fuse) more common if the radio was replaced with an after market unit. Also make sure the ground strap on the radio is connected to a solid metal part of the car.

Check the cruise control fuse. you have two fuse boxes; one underhood and another under the dash on the drivers' side.

try having the crank sensor changed. and check the ignition coil by your mechanic

Replace the fuel filter and have the injectors cleaned.

if its the same as the lantra its in the engine bay passenger side one end is fitted with a not on the fuel line the other is pushed in then held with a small bolt slightly offset from the pipe
