Tires would be the 1st place to check. If you seem to feel it more in your legs then it is likely the front, if felt more in seat bottom then could be a rear tire. Depending on how severe the vibration is there could be a tire developing a tread seperation and should be checked right away. A simple balance of the tire and wheel assemblies may be all that required also but when on a balancer they should be able to tell if the tire has a more severe problem.
Driveline components could cause vibrations also however if the above sounds like it fits then check that 1st.

SOURCE: car runs hot while idling

It`s easy to see if the water pump is working just drain some of the fluid out of the radiator and look inside while vehicle is running NOTE due this only when vehicle is cold.
Know if it`s not flowing after it starts to warm up then either the thermostat is stuck closed or the water pump is bad i would start with the thermostat if i where you the other job is a lot harder and more expensive
Also the fluid disappearance could be caused by the fluid boiling out when it gets hot one last note check pressure cap on radiator for wear or cracks if bad replace hope this helped you.

SOURCE: how can you tell if your water pump is bad

It could be either hose or the pump. Introduce no more antifreeze to this car until you have found your leak as you are just wasting your money.

You are going to have to visually inspect it for the leak. Typically if it is a pump, the pulley and the underside of the pump will be wet.

I have a 1999 Ford Taurus that would not heat, took to shop they flushed the system, replaced the water pump and it ran hot after thet flushed the system took it back they flushed the system again and


Did you have red antifreeze prior to the flushing? Ford engines are generally aluminium and should be using blue antifreeze which is suitable for aluminium engine blocks! I think the antifreeze is reacting to the aluminium.....re flush and use blue!

THE COOLANT LEVEL SHOULD BE AT THE FULL HOT LINE.ALLOW THE ENGINE TO COOL UNTIL THE AMBIENT TEMPERATURE IS REACHED THEN CHECK THE COOLANT LEVEL IT SHOULD BE AT OR ABOVE THE FULL COLD LINE.ADD MORE COOLANT IF NECESSARY. WARNING BECAREFUL WHEN OPEN THE RADIATOR CAP OR JUG OVER FLOW CAP.USE A LARGE RAG OVER THE RADIATOR CAP TO KEEP FROM GETTING SCALDED.OPEN RADIATOR CAP A LITTLE AT A TIME TO KEEP FROM GETTING SCALDED.WAIT UNTIL ENGINE COOL DOWN BEFORE OPENING RADIATOR CAP OR OVERFLOW JUG CAP.WEAR SAFETY GLASSES.

My heater blows cold air when car is stopped. i have installed a new water pump and the radiator is full of water.


you still have air trapped in the cooling system. Get front of car as high up as you can on a hill. Cold engine - loosen radiator cap, fill with 50/50 antifreeze mix. Start engine and run until upper radiator hose is hot (thermostat open). Engine should burp air and maybe spill some coolant, that's ok. Once burped, tighten cap, shut off engine and let it cool down while keeping the reservoir full. It will **** coolant out of reservoir as it cools. Keep it full.

If still cold air, take to a shop that has evac/fill equipment; they will **** air out and repalce with coolant. About $80.

How many gal of antifreeze should i put in the coolant system? I put 2 gal in as there was little left in the system. I went to drive the truck and within 15 min the truck was over heating. The antifreeze...


Was it knocking in the radiator when it over heated if so you most likely got an air lock in the system by pouring the new antifreeze in to fast. You need to add it real slow and once you think the radiator is full start the truck and let it warm up and leave the radiator cap off until the thermostat opens and then add more antifreeze because when the stat opens the level will go lower. Once you are sure the antifreeze is circulating an full then you can go drive the truck. Some people use a 50 percent mix of antifreeze to water but I always use 100 percent antifreeze it runs cooler.

Antifreeze/water leaking . puddle underneath van already got new thermostat, radiator is full overflow box full. can't see where leak is coming from. either from below or above view is blocked by other...


May not be either. Does the van run hot? If it doesn't then the coolant when it is heated is going to the overflow reservoir and if that fills up then out the overflow line to the driveway or the garage floor but everything is O.K.
