99 dodge ram started overheating all of a sudden a sputtering sound came from directly behind glovebox then the temp went back down what could this possibly be?

If the heater matrix is buried somewhere behind the glovebox, the noise could have been air or combustion gas being pumped through the matrix.

Cylinder head gaskets normally allow small amounts of combustion gas to escape and the cooling system is designed to allow it to rise rapidly above the coolant level, often with additional ports and vent hoses leading to the degassing tank.

If the degassing system becomes blocked due to the cooling system being dirty or corroded the gas bubbles can build up and displace coolant and disrupt the thermostat operation and eventually be forced into the heater matrix causing a vapour lock.

A failing head gasket will have a similar effect...

These things will need checking. Overheating is invariably caused by insufficient coolant circulation and/or insufficient cooling air flow through the radiator.

Passenger power door noise opening or closing

Can you be more specific? Is it kind of a glug glug or click click but deeper? If so it is doing the same as my 2005, check the upper roller/bearing while opening and closing. I fixed mine by spraying White Lithium grease on the roller/Bearing

My 04 camry is making a noise like liquid being suctioned through a straw. Similar to the noise you hear during a teeth cleaning. It seems to be coming from or near the steering column, and is loudest...

This is possibly the heater core making noise as coolant pump through the system. There may be excessive air within the cooling system creating that noise. This may be signalling coolant loss or if there has been repair/service done recently (water pump, timing belt, radiator, cooling system flush, coolant change) its possible the system wasn't bled properly. Either of this allows air into the system.

Took my van in for and oil change and the head gasket was leaking so they replaced it now the van smells like antifreeze and makes a gurgaling sound like there is air in the system and hums almost like a...

First double check the coolant level, the gurgling noise is probably from an air lock created when refilled. Check by removing the rad cap, not just reservoir level. Top up coolant level if needed, the noise should go away shortly. The coolant smell is most likely from doing the job itself. If it wasn't drained properly, some coolant will spill onto or even into the exhaust system. When it heats it will smell like coolant until burned off. The hum noise I'm not sure, alternators create more of a whine noise. It could also be from spilling coolant on the serpentine belt, it may squeal for a while afterwards. A good technician will always, drain coolant fully first, and should shampoo the engine after the job to eliminate any mess they created. If any of the noises continue, or the coolant is still low after a few days, return it to the garage for further diagnosis.

Was driving my 1999 chevy venture this morning after 12 miles had no heat & temp gauge pegged in the red. then went down & came right back up. Stopped & turned it off for 20 minutes or so. ...

You are describing a slow coolant leak and the resultant no heat and blockoverheating symptoms. The no heat is because there is insufficient coolant to cycle through the heater core, and the chuggin you describe is the engine indicating serious overheating.
With engine cold, you must add water--not anti-freeze--to the radiator itself, until it reaches the top of the radiator, then start the engine. If you do not have a radiator cap in addition to the overflow bottle (some vehicles don't), you must still add water to the radiator, even if you have to bypass the overflow bottle hose to do it. Add water until no more will go into the radiator. Start engine, let idle until operating temperature is reached. Thermostat should open and a good bit of the water will "sink" into the depth of the radiator. If you have no radiator cap, observe the temperature guage. When it reaches normal operating temp, when the thermostat opens, the temp will drop briefly at first, and you will notice warm air from the heater/defroster.
Once engine is warm and known to be full of water, seal radiator cap and/or system, and let idle for 30 minutes. Use this time to locate the "mystery leak." They can be very hard to find, and some won't leak until after the engine is turned off. During this idle period, observe the vehicle exhaust from the tailpipe as well as looking for actual water leaks: sometimes a bad head gasket can be diagnosed this way; if the exhaust is white and thick like steam, and smells like anit-freeze, you have a more serious problem. It is possible that after the repeated overheating cycles you have endured you may now have both a "mystery leak" and a blown head gasket.
Once leak is located, your next step is to let engine cool completely, drain the water, fix the leak, and then and only then add new antifreeze of the proper rating and ratio recommended by Chevy for your vehicle.
Anytime you drain a cooling system and refill it, it is necessary to check the overflow bottle at least 3 times in the first week after repair to ensure that you have the proper coolant level, and have not either missed another leak or not correctly repaired one. You MUST check it before you drive the vehicle the second time after the first repair attempt because it is normal to need to add more coolant than you added initially after the repair because of air trapped in the cooling system that will only be expelled after the first start/stop heating cycle. If after 1 week of daily normal driving you have only added a little more coolant once, and there are no more problems, you can be very comfortable that you have fixed your car.

2006 Chevy Trailblazer makes THUD when accelerating

Check your coolant level, low coolant or air in your cooling system will make a "thud"noise in your heater core when the engine is under load from acceleration. The coolant rushes in to the heater core where the air pocket is trapped and then your hear the noise.
Start with the simple and make sure your coolant level is correct and then try to purge the system to remove the air out for your coolant system.
Thank you for using fixya and good luck
