Daihatsu Applause Cooling system problem

Head or intake gasket leaking into cooling system.start it with cap off cold and see if it keeps bubbling. If yes compression is leaking into cooling system.

Possibly blew a head gasket allowing combustion gases to enter the cooling system and force coolant out of the overflow tank. This can be verified by doing a compression check on each cylinder.

In many cases of gurgling cooling system, you have a possible head gasket problem starting and the combustion from the engine is pressurizing the cooling system. Check your cooling system thoroughly for evidence of a possible blown head gasket.
Are you loosing cooling system water?
Is your radiator overflow tank being pressurized excessively by the engine. Headgasket problems can sometimes put some much pressure in that overflow tank that it begins to bulge outward.
Check the oil and look for any white/greyish milk shake consistency fluid on the oil fill cap or on the radiator cap. Keep a close eye on your oil and water levels if your gurgling sound continues. This is not normal and again, usually is a sign that there is a possible leak between the headgasket and a water jacket on the head.
Did you overheat the vehicle anytime soon? This will many times breech a head gasket between water jackets and begin spraying water in small amounts right into the engine cylinders, while it pressurizes the cooling system and makes gurgling noises.

have a compression test done as that will most likely be a blown head gasket or cracked head allowing combustion pressure into the cooling system. A quick check is to remove the radiator cap and fill right to the top . Run the engine and if you see small bubbles in the water or it tends to belch out then it will be the gasket of cracked.

Have a cylinder leakage test performed to check your head gasket. It dosn't have to overheat to have a head gasket problem. A leakage test checks if looseing combustion gases to the cooling system which would presurise the system higher than normal which causes the tank to overflow.

Few things to consider here. Have you had the coolant system pressure tested? If you have and it has passed then the problem is probably a blown head gasket or cracked head.

The Charades are prone to blowing gaskets (Diesels moreso) and overheating before it shows up on the temp gauge. This leads to the head cracking.

One easy way to check for a blown head gasket is to pop the cap on the overflow tank and with the engine running see if there are any bubbles in the coolant in the tank. If bubbles are there and constant the gasket it blown and worst case your cylinder head is cracked also.

Hope this is helpful.

Source: I work on Charades

air in the coolant
clogged radiator
collasped hose
loose belt to water pump

This is caused by pressurisation in the cooling system. Most likely is that the engine cylinder head gasket has failed. You need to go to a repair shop and get it tested.
Hope this helps

about 100K miles? sounds like a blown head gasket is allowing coolant to be pushed out the exaust,and combustion pressure is pushing fluid out the overflow.have your compression tested.

It shouldn't be bubbling into your overflow tank.If you follow the top radiator hose from the radiator to the other end of the top radiator hose the housing it connects to has your thermostat inside it.
