    That would be fine if this was a normal car, but it's not. It's a saturn. It seems that the thermostat is connected to the water pump in this car and i can't find that. any other suggestions please.

2004 mercury sable keep overheating. replaced drive belt and thermostat. now water pump appears to be leaking.

Don't mind helping but there are several pictures as well as written instructions. To much to cut, paste and all that stuff on fixya plus there is a size limit on pictures as well. If you want, email me directly at with your vehicle information (year, make, model) and I will be happy to make up a PDF and email it to you with pretty detailed instructions and pictures. It won't cost you anything but will need to know if the 8th digit of your VIN is a S, 2 or a U so I'm sure I give you the right information.

2004 grand prix overheating

Sounds like it got overheated too many times (once is enough) and now has either a blown head gasket or a cracked cylinder head, or both.

2004 Dodge durango is overheating

Hi, overheating can be caused by a number of things, but it depends on the situation, if there a greed fluid (coolant) dripping under your car than you are losing the coolant which keeps your engine from overheating, if there are no signs of leaking, than you might have a bad thermostat which is either not opening, or opening at too high of a temperature. If this is so, than i recommend replacing the thermostat. (make sure to use the same temperature rated thermostat as the one that is currently in the vehicle) also when you put new coolant back in the engine, make sure that it is a 50/50 blend of coolant and water, because a too rich mixture of coolant can also cause overheating.
Check the following after the usual fluid and belt condition/tension checks: 1. Fan clutch may have died, or be dying. It is filled with a silicon oil and should lock or get very stiff when the engine is hot. After warm-up, turn off the engine. If the fan spins a bit clutch is bad. If it doesn't severely resist turning by hand it is likely bad. If it has over 100k on it it is likely time to replace it. If the electric fan runs often under normal conditions it is bad. Hayes makes a good replacement. When I changed mine I increased miliage by 1.2 mpg because at cold start it takes a while to distribute the oil inside the clutch, and a new one does that better and faster. BTW - That is why the engine roars so much when first started and shortly gets quiet. 2. If overheating under heavy load shift out of overdrive, or downshift as operators manual instructs, and slow down some. Use the tachometer to avoid running at too low or too high an RPM. Turn off air-conditioner under heavy hot loading. 3. Keep the fins on the front of the radiator free of debris like bugs and dirt. CAREFULLY straighten severely bent fins to promote airflow. 4. If you find yourself in an overheating situation and are pretty sure that it isn't a severe mechanical fault, then try turning on the heater(s) with all of the windows open. The heater cores are small radiators, and more fluid is now running through the system. Of course, the air-conditioner is off already. This trick got my wife and 12 year old son safely to Mammoth up a steep grade - he thought of it! 5. If this condition continues after these issues resolved there is likely a mechanical fault that needs a professional mechanic- like water pump, clogged radiator, failing hoses (hard to tell how bad they are inside of the hose!), head gasket leak, timing, spark plugs, or other such fault with emissions systems (although these will likely give a "check engine" warning), and poor fuel.
Take care

How to replace my coil pack.?

gonna have to be more specific... what type of car? Usually a coil pack is just held down by 4 bolts. Not sure what car you are working on, but it's generally pretty self explanatory. Just look at it. Just one suggestion. replace one wire at a time. Take one off, put one on, take one off, put one on... just so you know for SURE you have the firing order right.

My 2004 dodge intrepid is overheating how to git

Remove the top hose, unbolt the thermostat housing, remove old themostat and install new unit with new gasket. Replace top hose and fill with coolant. Be sure to re-check the coolant level after start up, beore you drive it anywhere, to eliminate any air pockets in the coolant.

1999 dodge b2500 van is overheating.

I know this solution sounds kinda dumb but if you just replaced the thermostat I would check to make sure the thermostat is installed the correct way. I replaced the entire cooling system on one of my vehicles once and it still overheated....I put the thermostat in backwards. Turned it around and problem solved. Hope this helps and please don't forget to rate me.

It is an electric assist steering. On very heavy use the motor can become overheated and goes into "safe mode" only partial assist until it cools down. Repeated attempts at parrallel parking have been know to cause this.

The thermostat is located behind the alternator. Atleast on the 1.8t it is. I had the same problem and same symptoms. I hate to tell you this but its probably not the thermostat. Its the water pump. They have plastic impellers on them that that deteriorate after a while. Make sure if you get your water pump replaced you get one that has a metal impeller on it. You should get a new timing belt well they are in there as well. They have a pretty good deal on kits at
