We have replaced heater valve, thermostat, radiator and both hoses fresh antifreeze, flushed out heater core. But once warms up and heat on blows hot for about 10 minutes then gets cooler. If you turn off wait about 10 minutes and turn heat back on it blows hot again, thus is repeat process lately and not sure what else to try

I just got an oil change and now the oil is leaking in a number of spots across the middle coming from somewhere around the top of the engine. Not sure if the two are related or just coincidental. How much to repair, is it worth it, or is it time for the graveyard?

I was told that to gain access to the fuel lines gong to the fuel tank, I can remove a panel from the hatch instead of dropping the tank? Is this accurate?
Hyaundi Santa Fee 2003 developed a fuel leak. Question is can I use a high pressure plastic line to connect the line after cutting out the bad part? I tryed using what Auto Zone called high pressure rubber hose with clamps and it never worked
How difficult is it to replace a fuel line in this SUV
I just noticed a puddle of oil/diesel under the car, wasn't there this morning. I've just driven a long way and just arrived home. i've opened the hood & when I start the jeep a spray of this comes out of a top section of the engine can anyone help? Not very mechanical - minded. thanks
I've been trying to repair the a/c which suddenly stopped working on the auto select. Will work but only runs with the blower on high and at whatever temp is set. It's too cold with the a/c running on high blower all the time. If you decrease the blower speed it shuts the a/c off. Can't afford to go to the dealer. I have replaced the control panel without any change in symptoms. Any help? Thanks
I have had it diagnosed at least 3 times, including once by Hyundai Dealership. Codes for Camshaft and Crankshaft Position Sensors. Replaced Fuel Pump, both Coils, Spark Plugs and Wires, Crankshaft Position Sensor two times, Timing Belt, Balancer Belt, Camshaft Position Sensor, and Throttle Position Sensor. Hyundai says 99 percent sure the problem is ECM. Had someone else replace ECM, Still not fixed. It started out by dying while driving down the road. It would start for 2 seconds then die. After it cooled off it would start and go for maybe 5 to 10 minutes. Then same thing over again. Now it will start and run while missing out until it warms up. Then it smoothes out but sometimes acts like it might quit when at the stop light. The mechanic that worked on it last says he can fix any car, but not this one. I have it home now, trying to find help here. The check engine light is on now again for a Camshaft Position Sensor which has already been replaced 4 times since April of this year. Any and or all help is greatly appreciated.
