boiling sound coming from reservoir?

Question

i have a 97 plymouth breeze i replaced thermostat tempature gauge is in normal range

Answer 1

Make sure the radiator cap is screwed on properly. I had the same problem. There is a possibity that you have air trapped in the system. Get someone to check it out for you.

Answer 2

The reservoir is meant to catch the extra coolant that's formed as a result of the hot coolant expanding. There should be a full cold and full hot mark on the side. Fill it up to those levels depending upon whether the car is warmed up or not and I doubt you'll hear the noise then. If anything, the noise is probably just the expanding coolant being forced past the radiator cap. In addition, when a hot car is shut off, sometimes the fluid in the radiator boils for a bit since there isn't any cool air blowing through the radiator as there is when you're moving. If so, nothing to worry about unless it spews out of the coolant reservoir. I've been a parent for a long time, so I'll tell you too, NEVER open the radiator cap when the engine is hot because you can be severely scalded! NEVER!

Answer 3

You may be low in coolant in the engine/radiator. Sometimes the radiator cap or the hose from the radiator to the reservoir will not let the coolant flow from the reservoir back to the radiator. This would result in overheating, boiling of the coolant, and steam flowing to the reservoir. Thus the bubbling sound. Check it when the engine is cool, by removing the radiator cap, and making sure the coolant level is close to the top.
In some engines when the coolant level is very low the temperature gauge may mislead you.

Answer 4

Ahhhh the good old Plymouth Breeze. I had a 98 and it did the exact same thing.

You are not going to be happy, but they are well known for this problem. We are talking head gasket problems and it is not cheap to have this fixed. Probably looking at the $7-800 dollar range.

My advice is trade it off before it really gets bad because when you put the cost to get it fixed on to the value of the car it isn't worth fixing.

Answer 5

really need more info on this, does it overheat, is the antifreeze at it's proper amount, is the radiator cap good, does it heat up while running or idle, why did you replace the thermostat, is the timing correct, are the hoses in good shape, is the water pump belt tight and in good condition, what temperature thermostat did you put in? there are many things that makes a car overheat, when water boils in the radiator the engine is to hot, and the coolant is not removing that heat properly.

Answer 6

you may have a pocket of air in the system.Some times trapped air will work itself out of the system by just driving the vehicle (heater on) a few times,as long as it is not overheating.The best way to remove the air is with a flush and fill kit.Prestone makes a kit that most auto parts stores carry,works good to purge air out and get debris out of the system.

Answer 7

You need to check your fluid level,you sound low or your water versus anti-freeze mix is too much water,you should run 80% coolant and 20% water.

Answer 8
