Next thing to check is ignition timing. If something has happened to change the timing, that can cause overheat also. Also, need to make sure that timing advances properly under increased load.

I have a 2003 xg350l the bottom radiator hose dos not get hot.At an idle the car does not run hot drive about 5 miles and it gets hot but radiator hose does not.

Hard to say what that problem is given your description. I think that you should give more information about the driving time and what and when it heats up, like 5 or 10 minutes after your driving, and record temperatures. Is the temp higher than your car's specified rad temperature, after say 1 hour of driving? You may have blockage in the rad hose, but this is doubtful.

2000 GMC Sierra SLE 5.3L overheating replaced the water pump, thermostat, fan clutch, & flushed radiator and its still overheating

here are 8 reasons a vehicle over heats. coolant level is low, you have a leak in cooling system, the cooling system may have trapped air inside, the radiator cooling fan is not working, radiator core has become plugged, bad thermostat, or bad water pump, or Your radiator cap needs to be replaced. Good-Day! this is mostly all problems with over heating. if it is a bad head gasket, you will see white smoke from tail pipe. thats because coolant is entering cylinders. as for the radiator cap have a parts store pressure test the cooling system, if they do it.

My opel keeps heating up and the fan is running, when u drive to long it starts to boil and goes in the red what do i do

Adele, the over heating can be the result of several things.

1. The coolant (antifreeze/ water mixture) in the radiator may be low. This could be from a leaking radiator hose or a leaking water pump.

2. The radiator is clogged and is not distributing the coolant properly. The Radiator will need to be drained and flushed with radiator flush. Then flushed again with clear water and new coolant installed in the radiator.

3. The engine coolant thermostat my be locked closed. This requires replacing the thermostat.

As you can see, there is more than one thing that can cause the engine to overheat. But, these are the things that you troubleshoot first. I hope this helped you & thanks for choosing FixYa.

My mercedes s430 2002 is over heating when im driving

John, the radiator may be low on coolant and needs to be topped off. In addition, there are several other things that could cause the overheating: Clogged radiator, engine thermostat has failed, leaking radiator hose, radiator cap needs replacing - are things to start with in troubleshooting the problem.

Good luck.

I have and overheated promblem with my 1993 jeep chorekeee country . What can it be

Chris, unfortunately, it can be caused by a host of things: Low radiator coolant, a clogged radiator or engine thermostat, a leaking coolant hose, faulty radiator cap and the list goes on and on. However, it's best to start with the easy things, like Low Radiator Coolant, because that's easy to check. Just make sure the engine has cooled before removing the radiator cap. While you're waiting for it to cool, look in the plastic coolant overflow tank. If there's no coolant in it, more than likely, when you remove the radiator cap, you'll see the coolant level is low. However, if it appears full, it may be that the radiator is clogged and needs to be flushed and new coolant put in. If the coolant in the radiator looks like old coffee grounds, nine times out of ten, the radiator is clogged and seriously needs to be flushed.

Also,pull the oil dip stick and look at the color and consistency of the oil on the dip stick. If it's a milky color, your engine has a blown head gasket and that's where the coolant is going.

As I said before, it can be a "host of things". Just start with the simple ones first.

Hope this helps you in starting to troubleshoot the problem If so, please leave me a good rating. Thanks!

My 1992 Honda Accord runs hot when I stop at a stop sign and the temperature gauge goes up like it wants to run hot but when I take off the guage goes back down. There is also smoke coming from under...

That's not smoke coming from under the radiator cap, it's steam. The radiator may be low on coolant or is clogged or the engine's thermostat is stuck closed or all of the aforementioned. Whichever the case, it needs immediate attention, before the engine blows up from overheating.

Try flushing the radiator with a commercial grade radiator flush. The radiator sounds as if it may be clogged and not distributing enough coolant throughout the system. The factory coolant GM uses can really screw up a coolant system over time.

Amana HTM (heat transfer module) system

I would check the house thermostat(and its wiring to the indoor unit), and if it's OK then check the heat transfer fluid diverter valve inside the indoor unit (should be sending the hot fluid through the big radiator (air exchanger)) until the surface temperature of the radiator is approximately 130 degrees F, then the fan control operates and the fan starts to blow hot air through your ductwork. My HTM is 26 years old and I've had many opportunities to "hone" its operation...
