SOURCE: Engine coolant hot

fill the reservoir with the coolant. it is a GOOD thing you dont see steam or a leak I hope.YOU DO WANT TO CATCH THE PROBLEM BEFORE IT REALLY OVERHEATS OR YOU MAY HAVE MORE COSTLY PROBLEMS. fill the reservoir. BUT, it may only fill the "radiator" once you do this as it cools off. As the radiator water cools it sucks the reservoir water into the radiator. as it heats up and the water swells (increases in volume) it pushes the excess into the reservoir. when the engine is good and hot and you dont have any coolant in the reservoir, that is a sign that the radiator is low or empty also.
when the engine is cold, find the radiator cap and remove it, add as much coolant you can there. fill the reservoir also. If it has been several years since the radiator cap has been replaced, I would do that now ( it is a cheap investment). if the gasket on the cap is not sealing well anymore or the exspansion valve mechanism on the cap is not working properly anymore, then it will let coolant pump out into the reservoir and not hold radiator pressure. if the reservoir is empty the radiator itself is probably too low or empty.

Sounds like there might have been some dirt or sludge in the bottom of the tank that got sucked into the fuel system. First run some fuel system cleaner through it. If that doesn't work change the fuel filter.

My 1994 Mercedes c220's fuel gauge stopped working


Fuel level sensor is in the gas tank, may be faulty or just dirty, make sure to fill the tank entirely full with premium unleaded, ad a high quality fuel system cleaner / de-gunker, this may clean the sensor enough to feed back to the gauge. It could also be the fuel gauge itself, but that is less likely. Mercedes will be happier with at least 1/4 tank of fuel at all times, and don't skimp on low octane gas!
As for the check engine light, you may have a bad gas cap... believe it or not a gas cap that doesn't seal properly will throw the check engine light. If you get the codes read (for free) at an Autozone or similar parts store it will likely read "evap system" as the problem, which will likely end up being the gas cap.
Take your car to a service center that does a true "flush and fill" of your a/c system. Those little canisters will just waste your money, and they never truly clean and re-lubricate the system like a flush and fill will do.

1995 Chevy Astro rough idle after choke goes off and engine is at full operating temperature, also no check engine light.


Inspect/replace air filter.
Fill the gas tank to above 3/4 and add Lucas FUELSYSTEM CLEANER.
Ran on the highway for 10+ miles.

Monitor is the rough idle condition is getting worst on below 1/4 tank.
Change fuel filter and check fuel pressure.
Most failing/weak fuel pump will not work well below 1/4 tank mark.
It will fail in a HOT DAY.

Added Fuel Line Cleaner & now the Check Engine Light Wont Go off!


The cleaner won't hurt it at all at any fuel level.
The light could be MANY things.
Just have the codes checked and you will know what it's asking for.
Driving it with the check engine light on will reduce your mileage and increase emmissions about 20%........and thats all.
Enjoy your drive to Boston.

Take it back to where you had it serviced. They probably simply missed connecting the fuel level sensor. The engine light is probably from a missed emissions hose that goes to the gas tank.

Hesitation going from like 0-20 and up hills


Could be similar to my car. I have to use a fuel injector cleaner additive to get rid of hesitation. Not sure about the check engine light. You need to have a system analysis done by your mechanic to identify that one.

Check engine light on in our 2005 Jeep Liberty


Drop in to autoparts place & get free code scan & go from there. (write it down & get back to us, or ask them at store.) Autozone & Pep boys I believe will do free scan.
