Engine overheating

Check the fan when it starts overheating and make sure it is running. You may have a faulty fan clutch. Also, check your water pump with the vehicle running and make sure it isn't cracked or leaking.

You can't check a thermostat like that. The thermostat should open when the coolant reaches a certain temp. To properly check it, remove it and place it in boiling water to see if it opens. There are directions on our homepage under the DIY section.

Let me know what you find.

When it gets hot or even overheats, shut the engine off and make sure your fan doesn't come on if it's electric. Then put your hand against the radiator in different areas. If it is cold anywhere then your radiator is plugged or plugging. It should be the same temp all over. You could get radiator cleaner and try that but it doesn't work all that well. If you do get that stuff get the stuff by prestone and not the flush stuff. Then drain your radiator by removing the lower rad hose. Drain all the coolant out and put the cleaner and water in. Run it for 100 miles then drain and change to a 50/50 mix of antifreeze. That is the best mix for cooling as well as winter protection. You could also add the stuff for making the car run cooler, that's been out for years and works fairly well. There are several manufacturers of that stuff.

Was the coolant changed at the 5 year period (2007) like it should have been?

Is the gauge in the red zone?

Need a little more nfo on what is happening on this.

No heat and smell like burnt coolant
Check if leaking coolant at and or around the intake manifold gasket
If had heat prior to engine replacement we assumes that the heater core and blend system OK and problem is related to the used engine that was replaced and should have the shop look at it

That's pointing to a leaking heater core. You will be overheating soon so stop driving it until it's fixed.

Based on your description, it sounds like your intake gasket is leaking. This is a common problem. If you can, take a picture of where it's leaking from and upload it for me to see.

Does it only overheat when you are in town or does it also do it at highway speed?

Le tme know.

Check for coolant getting into the combustion chamber.

One way to test for a bad water pump is to squeeze the upper radiator hose when the engine is hot and idling. Careful, because the hose will be HOT! If you do not feel much coolant circulating through the hose when you rev the engine, the pump may be bad. The other cause might be a bad thermostat that is not opening properly (remove and inspect the thermostat), or a clogged radiator

If it continues get it block and pressure tested also pressure test the cap
