On 6/19/11 comeing from town I saw the temp got to about 215 checked the water its ok got home cooled down some removed cap started it up let run about 15 minutes did not see water moveing temp was about 195 drove it about 5 miles temp went to 200 out side temp 100 in mississippi

Hi,lets start at the begining,resons for this can be,firmastat not working properly,fan switch not working properly so fan dose not switch on,waterpump not working properly so not pumping water around properly,radiater got sludge in it so is not cooling properly,or headgasket broken,
first start engine and wait for car to start up then when the tempreture gage gose up to normal running temp lisson for the fan if it dosnt come on proberly temp-switch for the fan,if fan dose come on switch engine off and check that the hoses to the rad are bouth hot,if that is ok,wait for the car to cool down a bit so you can take off the exspantion tank-cap put a cloth or some thing over the cap as there is a lot of presure and hot water,so be carfull not to burn yourself,
when done start car and look to see if the water is moveing around freely if so then the pump must be ok swich engine off,last one take of the oil-filler-cap and look at the oil it should be brown in coulor,if its a musterd coulor then it means the head-gasket has gone,well although ive sied all this thay have a tool on the market wich the garage use to pump presure in the water system wich shows up eney leeks,if you are loseing water apart from the bubbling water that comes out of the exspantion tank that will show it up,I wish you the best and hope its one of the miner jobs.

Could be a blown head gasket. You might also need to "burp" the system. When the vehicle is completely cooled down, try taking the radiator cap off, topping off fluid, and start the engine. That should help get air out. If it starts bubbling and shooting coolant out, something is wrong. You could also try running without the thermostat or just go ahead and replace it. They aren't usually expensive.

Sounds like possibly water pump. Sometimes the fins break inside and doesn't circulate enough water. I would start there

Check your coolant level. Especially after you drive it and it starts to cool down. You have air in the system and it needs to be purged. Sad to say but chrysler/ dodge are bad for this problem. Some times you have to remove the hose from the heater core spout to get it purge correctly. You have to do this while it is running.

Could be a faulty water pump, clogged or stuck Thermostat or clogged radiator. Once the engine cools down remove the radiator cap then start the engine and wait for it to warm up to operating temperature. At operating temp you should be able to see the fluid in the radiator circulate. If you don't then you need to let the engine cool again and remove the thermostat or replace it. And run the same test again. If you still don't see the fluid circulate then replace the water pump.

Most Hondas and modern car fans can and do run at will. 215 on a scan tool is just reading the sensor and variation is ok. A temp gun is more accurate. Ill bet your gage is still normal. I have a honda and the fan runs at times when I get out. Normal

You most likely have air in the cooling system.You would need to bleed the cooling system of air.There should have bleed screws near water neck,or thermostat.Do this cold.Remove the radiator cap and fill full.Then start the engine and loosen the screws and watch for nothing but coolant to flow out(no air or bubbles).When you are sure the air is gone out of the cooling system,shut the bleeder screw off,and fill radiator up and test to see that engine runs cool,and you have heat at all speeds and rpm s.The electric cooling fan should come on at a tempuratue of about 215 or so.But just as important,the cooling fan should cut off at a lower tempurature.If the cooling fan does not do this,you still have air in the system.If you can not get the air out this way,then do this.Remove the radiator cap and reservoir cap and fill them both up full.The reservoir needs to be over the fill mark a good deal.Replace the caps.Start the engine with ac and heat off.Let it run until the engine gets to about 212 or 215 degrees and shut the engine off.Wait about 30 minutes and check the reservoir to see if the coolant has dropped.It should have dropped.If the reservoir has dropped or not ,do this again and again untill the reservoir drops in coolant level,and engine temp is good(fan goes on and goes off).Remember to refill the reservoir as needed as it drops,not to run out of coolant.

You need to find out if you are getting any coolant flow. Look for any signs of restrictions. You could try measuring the temp of the inlet hose and comparing it to the temp of the radiator outlet hose, there should be about a 20 degree difference. Next step is to test your thermostat you need to be sure that it is opening properly. First let the car cool down, drain the coolant and remove the thermostat. An easy way is to take some hot water and measure its temp you'll want it around 215 deg f. Place the thermostat into the water and see if it opens up. If so it is working properly and you need to look else ware. Reinstall the thermostat and fill the cooling system make sure to bleed out all the air. Other possibilities are the cooling fan is not coming on, the radiator cap is defective not allowing the system to pressurize a worn out water pump not flowing enough coolant, or a restricted radiator. First off you should try bleeding the system it is possible that there is air trapped in it. Happy hunting.

hi its rob cylender head or cylender head gasket or ileak in cooling system check oil for creamy white sludge if non then take of radiator cap start engine see if it bubbles up turn of engine and smell into the radiator for fuel check accesive amounts of water or white smoke coming from tailpipe ether one of these maens cylender head of gasket blown

check and see if you get water/coolant circulates when you have the cap off (only check from cold start) the original water pump came with a plastic impeller and tends to strip on the shaft also check your thermostat before replacing water pump.
