2006 Maxima SE is running fine except for when you leave running in park we with or w/o A/C it over heats you cut off it's fixes itself

While engine is cold (i.e.: not running for 4 hours or more), check your coolant level. In many vehicles, if coolant goes down there is not enough cooling going on when idling and not moving. If low, add coolant to full line however, if coolant has not been flushed and replaced in over 4 years, just do a flush and fill with fresh coolant as per owner's manual guidelines. Even if that does not solve the problem, your engine will be better off!

If it does not solve the roblem, be sure the cooling fans are working as they should; sometimes, one fan does not work at all and that could cause an overheat especially when idling.

If all is good, there may be a clogged passageway somewhere in the coolant circuit - that should be settled when doing a flush and fill though.

P.S.: Remember to never open a radiator or coolant reservoir cap when engine is hot, you could seriously hurt yourself from boiling liquid coming out!!

What would cause the water to boil in the heater core of a 2002 caravan se with a 3.3

It would boil if the thermostat isn't opening and the water isn't circulating to cool in the radiator. Usually this is caused by an air pocket from an amateur filling the coolant into the vehicle.

Car keeps boiling tru resivour at side. all coolant boiled outta it found out it was a broken radiator cap. got new cap what coolant do i put back in and how much

Get the green stuff and mix it 50/50 with clean water. With the vehicle cool fill up the radiator until it is full and then fill the overflow tank up to the cold fill level. Start the car and take it for a spin making sure to get it up to operating temp, let it cool and then see where your level is on the overflo tank. Fill up to the hot mark and then repeat a couple times and you should be good.

I have purchased 2001 model Sebring Lxi. After driving just 20 miles I heard a sound of water boiling in coolant tank. Its too much boiling & sounds horrible. what should I do? Is this a serious Issue....

waterboiling in the coolant tank is not a good sign. water needs air to boil, and if you have air in the system, you are not getting the sufficient cooling you need to keep driving your vehicle. take it in to somewhere and havea coolant flush performed on it. if you would rather do it yourself, you can drain the coolant, fill with new coolant and add some coolant flush to the new coolant to clean out the system. NOTE. DO NOT leave coolant flush fluid in vehicle. You must remove the old coolant and fill with fresh coolant and bleed the system of any air to prevent your boiling. hope this helps.

Just been given a friends car to drive - Daewoo Lanos and I would like to check the water... where do I fill it? I can see the Coolant tank and the windscreen well but cant seem to see where to fill...

Dont use water. Pressurized system requires coolant/water mixture to maintain proper boiling point. Coolant is added to coolant tank you have identified, there is no direct fill to the radiator, it fills out of the coolant tank.

Its me AGAIN. Same car same problem. I changed my water pump, flushed and back flushed my radiator, and changed my thermostat. The engine ran nice and cool for 2 days and now we are back in the red with...

A bad cap will definately cause your problem. Put a new radiator cap on and your problem should be gone. The cap controls the pressure in your system (usually about 15 lbs) and for every pound of the pressure the boiling point of your coolant goes up by 4-6 degrees.

Radiator coolant or reservoir tank always full

Relax, there is no problem.

When the water / coolant gets hot (inside of radiator/engine) it starts to boil, ofcourse when it boils, it expands, so the fluid in the radiator has to go somewhere, thats why there is the overflow reservoir. So, when the fluid boils, some moves to the reservoir to avoid any potential problems with the radiator, such as it blowing up, or not being able to cool off all of the fluid running through the engine.

But relax, its normal.
