Get a pressure tester, and test it cold. You may be burning the coolant off before it hits the ground. Could also be literally burning the coolant in the motor.

My 2004 3400 closed system ,runs hot in town unless heater is on. driving up a mountain pass it gets very hot.on a flat highway runs normal. new t state,resivior cap, both fans work no leaks or smell


Radiator fan motor or radiator fan thermostat defective/

Also there is a relay that operates the fan motor

In town not enough air passing through radiator allowing it to over temp.. With heater fan running acts like cooling fan keeping engine cool

Highway driving ample air passing through radiator without fan.

Hill climbing requires cooling fan/

Hope this helps?

My engine smoke excessively even when hot. I hag the head gasket fixed about 3 years ago but its burning anti freeze regularly around town and not on the highway.


You still have a leak somewhere! It could be the Head Gasket/Warped Head, Intake Gasket, Timing Cover. Have a Mechanic look at this before you cause severe and costly damage.

1994 astro van does it have to be drove in overdrive


I would say it could. Especially for in town driving. It would help with the "searching for the right gear" that sometimes occurs at less than highway/open road speeds.

Also for any towing or heavier loads I would recommend NOT using overdrive.

For open road/highway I would use overdrive to get better MPGs.

Hope this helps.

Engine over heats


Check for collapsed radiator hose first.

Do the cooling fans come on? If not, check fuse, relay and if still no function- fan thermostat switch.

If fans do come on, replace water pump.

Our temp gauge in 2000 town and country van is running between 1/4 and 1/2 while at an idle but when you drive down the highway gauge drops to an 1/8 above the C and heater loses heat. Could this be...


yes, thermostat is most likely the problem.

Please see my tip at http://www.fixya.com/cars/r5929960-s_thermostat . These are generic instructions. If you get stuck or need specific instructions for your car, please get back to me with model, year and engine info.

I may have added too much coolant. After adding it, I drove for about 15 minutes. A few hours later, the tempurature gauge light came on. I check the coolant level again and there was nothing in the...


No, you can't add too much coolant. Rather, it does not hurt anything if you do. Did you add it to the radiator, or to the overflow tank?

Let it cool, then remove the radiator cap, and if needed, add coolant to the radiator. Put the cap back on, and fill the overflow tank to the "full - cold" line. Start it and run it a few minutes and look for leaks. If you find no leaks, drive it for a day or two, then let it cool and check it again. If it is down a lot (without overheating), you have a leak somewhere. If you lose enough coolant, that will make it overheat. However, if it overheats, that can cause loss of coolant, when you stop the car, you will see steam and smell coolant, and often hear it boiling.

If it overheats again, make note of when it happens: driving on the highway, or stop-and-go around town. Overheating on the highway usually indicates a clogged radiator, while in-town overheating usually indicates a bad cooling fan (you don't need the fan above about 30 MPH). A bad fan is usually the fan relay, but it can be the fan thermostat (different from the engine thermostat), or a bad fan motor.

2000 Chrysler Town and Country Antifreeze leak


I would replace the Thermostat and see if that will not Stop this. It is Coming from the Overflow Tank. It is getting a Little Warm during Driving and the Extra Coolant that will Build up Preassure needs somewhere to go So, It sends it to the Overflow Reservoir and it Seeps out the Overflow Outlet. This is Pretty Common though and Really not that Big of a Deal as long as you do not loose too Much. Please Rate My Response! Thanks!

If it runs at highway speeds then I doubt it's fuel filter. I'd check the operation of the idle speed motor. Here's a link to a diagram so you'll know what to look for & what to do. just scroll down to your engine (fig# 2 ) & click on small picture to expand it.
