Engine light stay on and off 1995 VW Jetta GLS

Recently change timing belt, water pump and did coolant flush. Everything works fine. But when I replaced my factory radio (does not work) with after market radio that's when things get crazy. The cruise control do not work and the engine light stay on and off every 40 to 70 miles drive.

It's just bad timing. Aftermarket radios have nothing to do with cruise control. Cruise control is attached to your cable line for your pedal near your throttle. It'a normally a box attached next to it. That is running on the battery separately and maybe a sensor to warn if it's not working properly.
The radio factory radio, is attached to many sensors in cars. If you have one that worked with volume contols on steering wheel than you might of sparked a problem. If that is the case (where you could control factory radio on steering wheel), than all you need is to go to the dealer and ask them to reset your gauges and warning lights. let them know whats up. Might cost you nothing. Also when replacing certain parts, the cruise control might have been tampered with and doesnt work.Or has been detached. normally you will have a blinking light steady, blink and it disappears. But check with dealer for the reset.

After they have done this, check to see if it occurs again. If it does, than it might be a shorted out wire connecting one of the sensors from the large important parts you had replaced earlier and it was just result of coincidental timing.

especially when replacing timing belt and water pumps. Even mechanics make mistakes!
Good luck.

Car overheated one day the fine the next but no


your heat is not working becuase the coolant level is too low meaning your heater core is full of air. the reason your car overheated is because the water pump impeller splines are gone and you need to replace the water pump. it is driven by the timing belt so replace that too. and the tensioner. this is the number one cause of vw overheating, especially on a diesel. i have replaced about 50 water pumps on this engine because of this.

Why does my paid off 2000 VW Jetta GLS make a high pitch buzzy grinding sound. Is it the alternator ,transmission,or timing Belts. What do I do and how mauch can it run me. Am I still covered with the


The trick is to take off the belt and spin the different things and see if any of them make the noise you hear.
Water pump, alternator, power steering, air pump, belt tensioner pulley. You could also briefly (30 seconds) run the engine without the belt and see if it still makes the noise.

(1) No need to know if engine block coolant drain plug was available. Once the water pump was removed, all engine block coolant was drained.

Finding Thermostat on 98 Jetta GLS


Its to the right of the water pump towards the bottom of the engine.. Follow your lower radiator hose. Make sure to get some G12 coolant from VW before you do it. If you mix the coolants they turn into a gel that will cause you to overheat.
