Sometimes the thermostat will stick closed. causing rapid overheating. Did you flush the system? The passages in the block, head and/or radiator themselves could be blocked, first start out by changing the thermostat, then flush out system with a good flush of system. if water pump is ok, and there is no leaks, and the coolant is up to par. then it should be ok. have a good one ! if you are loosing coolant then check for a bad head gasket or a leak in system.

Expansion tank overheating, have had the water pump, thermostat, radiator changed, now smoke is appearing from the engine and there is residue apparent aswell. Does this sound like a head gasket problem??...

It is most likely pressure from the cylinder that is leaking into your expansion tank, and with all the misdiagnosis, you have probably overheated the engine and severely damaged the gasket. I am afraid that you expenses are not at an end yet. You are looking at at least a cylinder head gasket replacement and a head skim. Plus a lot of flushing and cleaning out of the engine. I wish fir your sake the news could have been better.

It's possible that you have a bad head gasket. Have your cooling system pressure tested, see if it holds roughly 18lbs of pressure. Could also be air in system, did you bleed system when waterpump and thermostat were installed?

My 1997 honda accord is starting to get hot. My husband just changed the radiator. Just wondering what could be wrong?

Thermostat is clogging, water pump failure, air in cooling system, a leak in the hose. These are the obvious issues concerning overheating. Hopefully its not a blown head gasket. There is a 30 dollar diagnostic you can have run and the mechanic will tell you if its a blown head gasket. I should know. I have a bmw and i didnt get diagnostic and bam head gasket was way warped. Cost me 2200 for head gasket repair. This is what I recommend you do. Also you could run vehicle without thermostat and see what happens. if it dont over heat then it was thermostat.

Well, you could have a head gasket leaking into the cylinder.

There must be a leak somewhere.

Also, the system may need to be flushed.

Also, check to see if the water pump has been changed with an opposite impeller.

This happened to me once on a car that had the wrong water pump installed.

Good luck on this one.

1994 bmw 740i complete R&R FOR CCHANGING HEADGASKETS

There are several signs that a BMW has a blown head gasket, such as if the temperature gauge shows the car is routinely running hot. If the low coolant light comes on, even after topping up the coolant, it's leaking somewhere. Another way to tell is by opening up the engine's oil cap and inspecting the oil. If the head gasket is blown, the oil will mix with the coolant and the oil will have a brown, milky appearance. If white smoke comes out of the tailpipe even after the car is warmed, there is a good chance there is a problem.
There are several things you can to help ensure your BMW motor does not suffer from a blown head gasket. It is recommended you change the water pump every 60,000 miles or so and replace the thermostat if there is any sign of the motor running hot. Though radiators are expensive, it's a good idea to replace them every 100,000 miles or so. It is also possible to upgrade to an aluminium radiator on most cars as well as a better engineered aftermarket water pump. It's also a good idea to periodically have the coolant flushed and replaced.
Before you get into all of that make sure you bled the cooling system properly. Check for heat coming from your heater, you may have air in the heater core. Also replace the expansion tank cap and check the expansion tank for any cracks or leaks also. Sometimes you get a defective water pump or the some of the plastic from packaging get left on the thermostat and causes it not to open properly.

Go to a shop and ask for a cooling system pressure test.

After they pump up the coolant system,they will point out is there any INTERNAL or EXTERNAL leak(s).

Internal leak is the first sign of blowing head gasket. (NOT GOOD)

External leak can just a small hose.

Start monitor cooling loss.

Start monitor the oil level

Change the thermostat and gasket.

The temp sensor is cheap. Change it at the same time.

Use 60/40 coolant mix is you has high odometer reading like 160,000+ miles

DO NOT ALLOW the coolant and oil cross mix.

As soon as it mix,you are ready for a majot head gasket repair.

Good luck.

Overheating when idleling

Its not impossible for there to be a bad head gasket or leaking. But I agree with you the over heating will be there during driving as well. I would change the fan clutch and replace the thermostat, if the thermostat that was replaced wasn't an oem/delaer thermostat, I would change it. From prior experience with these type of vehicle the most likely cause of overheating thermostat and fan clutch. Aftermarket thermostat just aren't good for this vehicle I have proved it a few times for myself. Take my advise and change the thermostat with an oem one and the fan clutch with an oem. Good Luck. Get in contact with me if you need more help.
