CULTUS bubbles in radiator

[prince101]

I have cultus CNG 2006 , milage = 99k i face a problem of bubbles in radiator and some time radiator throws water in the bottle > their is no heat up issue > their is no sign of water and engine oil mix up > no somke from exhaust > fan is direct and thier is no thermostate valve > raditor is 2 nali , make = loards > radiator cap is changed , made in japan 3 to 4 days before i found water leakage from the heater pipes in bonnet i got to mechanic he change the pipe and also he found that the one little small point below the distributor is rusted so he took out that part and repair it. the leakage problem is solved but i face bubble problem in the radiator .I got to 4 local mechanic and one suzuki authorized dealersthe Suzuki authorized dealer said that the head needs to be service also the bubbles is due to the head gaskit and expense is 15k of head service 2 local mechanic also said that the head gaskit problem1 mechanic said that the gaskit is ok the system takes air form some where1 mechanic said that it is due to the thermostat valve put the thermostate valve and the problem gone Now i need the expert opinion from pak wheels members , please help me out .. thanx

1. Ur car is abt 99k driven & keeping in account that its a suzuki its not odd thats it needs head gasket job. but wait on it
2. B4 going any further u need 2 b absolutely sure that ur cooling sys is 101% ok. that it holds pressure. it is not leaking, its not reducing water
3. If its reducing water even in short amount then its leaking. leaking doesnt mean that u will find water dripping from somewhere. tiny leaks at joints only leak when engine is hot & water evaporates not dripping on ground. but u will see white color patches 4m where it evaporates.
4. Wats the state of engine oil. is it reducing oil?
5. What r u using in radiator, plain tap water or coolant?
6. There may b air in ur cooling system. remove air 4m it.

3. as i told you that their is a leak problem and i repair it but now car doesnot reduce water sometimes it throws water in the bottle and when i put back the water from bottle the radiator become full .
4. It doesnot reduce engine oil , engine oil is in very good condition
5. i bought this car in march 2012 after buying i changed the radiator and put CALTAX collent (2 liter collent mix with 2 liter water )
6. yes may their is a air for this i remove the radiator cap and start the car for 5 minutes after that i put back the radiator cap put the bubble problem is not solved

what you think about water pump pulley may be the system takes air from water pump . If the problem is gaskit then please tell me the cost of gaskit with labor ?

Gaskit problem

[prince101]

Gaskit problem

ok but their is no heat up issue and their is no sign of water and engine oil mix up

where is XULFIQAR and agoodfriend please experts help me out i am waiting for your opinions

[Xulfiqar]

search the forums for pressure testing the system, do it and you will find your problem, also check the overflow bottle - if the pipe going into it is leaking it will not suck coolant back when the engine cools down.

If you are seeing air bubbles and the heater is connected in the system - remove carpeting and inspect the heater pipes and core for any leakage (its also a small radiator), Now put the car nose up on ramps and remove the bleeder bolt from the top radiator pipe flange and slowly rev the engine while adding coolant - squeeze all pipes a number of times to work any air upwards, when all air is removed only coolant/water should flow from the bleeder hole. Tighten and top up coolant, check for bubbles at the radiator cap. There shouldnt be any.

And why have direct fan and thermostat is missing?

[Xulfiqar]

^Its a short cut cover up fix by local untrained mechanics of Pakistan, rather than repairing the problem they just try to cover it up and get their money in the shortest amount of time.

Thanks Xulfiqar bahi .. thank u sooooooooo much for your reply .. can your please tell me that where the bleeder bolt and bleeder hole is located if your provide any pic then it is much helpfull for me

Look in agood freinds thread - its near the top hose pipe flange and if you look at it, it would make no sense for a bolt to be there.

ok xulfiqar bahai .. so its confirmed that their is no GASKIT issue ??? and today i go to mechanic he says put the thermostate value in it and " phir agar bubbles ana band na ho to phir ap mujhay kahna " so whats your opinion related to this statement of mechanic

[Xulfiqar]

you have actually found a mechanic in Pakistan that wants to install a Thermostat valve - I would suggest a box of mithayee and some nazar etc.. first.

secondly the Tstat is part of the design so it should always be in place, the engine is supposed to operate at a minimum of 85*C temperature to be efficient. Install and check then systematically check if any problems show up. Do not confuse normal operation with fault - expanded water and coolant is supposed to collect in the reserve bottle. The system will be under pressure when working normally. The pipes would be hard.

According to XULFIQAR`s instructions , i remove the bleeding bolt , remove the radiator cap and start the engine the radiator throws all the water from the bleeding bolt then i pour more water into the radiator and radiator also throws the water out from the bleeding bolt , now i off the engine but the bleeding bolt back and add some water in the radiator and start the engine with heater on , pour more water into the radiator to make it full leave the engine start for 5 minutes and then off the engine and put the radiator cap back and take the test drive with AC on

After the test drive i again remove the radiator cap and start the engine now the bubbles comes after every 5 to 6 seconds but very small bubbles comes sometime one or sometimes 2 to 3 bubbles comes, before doing the above procedure the bubbles comes out very fastly and steadily and i also realize one think that when i press the upper hose pipe of the radiator the bubbles comes in radiator with engine on or off in both situations the bubbles comes but very small bubbles comes in very few quantity so now please i need some help from you please tell me how i remove this small bubbles and may be the air is trapped into the upper hose pipe of the radiator ?

[Xulfiqar]

you are supposed to run the heater all the time when you are bleeding air - hold the rpm at 1200 or 1500 during the procedure, you will get all air out. Put back, squeeze all pipes while bleeding including the small heater pipes too.

Park the car upwards to help and just bleed from the radiator cap as it becomes a high point.

how i can bleed from the radiator

[Xulfiqar]

how i can bleed from the radiator

it bleeds itself as air is lighter and rushes towards the cap opening, the engine and heater becomes a problem as the only openings are the pipe connections.

I bleed the radiator with heater on and squeeze all the water pipes but the small bubbles still comes in the radiator and after 10 to 15 kilometers of drive when i open the radiator cap it sounds like the opening of soda bottle
