Car troubles with my 2004 kia rio

no the crank and cam sensors have nothing to do with speed sensing. the wheel sensors are for ABS

That could be expensive to replace.....does the odometer still work? One work around would be to get a GPS for your car, it will show you your speed and miles driven.

Fuse, Dimmer control knob and the headlight switch

The solenoids are inside the transmission.

Hi.

Check that the fan is starting and working OK. When you drive the air hitting the front of the radiator may compensate a malfunctioning fan. When you stop without the fan working the radiator gets hotter and your dash tells you that there is overheating.

If the fan is working replace the thermostat that may be starting the fan too late. Also check fan fuse and relay.

Do not drive the car in this conditions. Overheating can easily cause damage to the head gasket. An head gasket problem will require a more expensive repair.

I have a 2004 Kia Rio and you have to take off the speedometer cable/wiring harness from the top of the trans and fill it from there...the drain plug/bolt is underneath the trans from there...

If the odometer still works then the problem is in the instrument cluster.If the odometer no longer registers then the cable is broken.

Check your sensor it is locatedby the transmission the tip of the wire has a blue plastic on it hope this helps out you dont need a mechanic at all,

you have to take off the speedometer cable/wiring harness from the top of the trans and fill it from there....one 10mm bolt...very awkward spot...it might be snug, so just take a flat head screwdriver from underneath to tap it loose...

No cable on that model Kia Rio you can check out connection on the back of speedo
