Re: anti freeze leak
Hi are you overheating and are you having to fill it up because it is leaking or were you just toping up and is it coming out of the overflow on the expansion bottle to find a leak that at first appears not to be leaking the best way to find it is to put a pressure tester on it see if the pressure goes down as it will if there is a leak but then you will see it and don,t take the water cooling systems caps off when hot yates210456

Could be one of a few things, but the most common and first consideration would involve a badly ruptured radiator hose which is leaking onto a hot exhaust system. Its should not be that difficult to isolate the hose and replace it, refill your radiator with the proper anti-freeze/water mix appropriate to your geographical area and take it from there. If it's leaking that badly, it almost has to be a hose, or more than one, or perhaps the radiator itself. . . this doesn't sound like, on the surface anyway a serious, expensive fix - even if it is the radiator itself.
if leaking from a hose change the hose. if from the ends of the hose change the jubilee clips.if from the expansion bottle cap .change the cap.but it may be due to air in the system if so put a radiator cleaner in the expansion bottle .run for about 20 miles .then drain and refill with a 50/50 mix of anti freeze.then put your heater on full run the engine till water gets hot .then refit the expansion bottle cap.to bleed out the air in the system.
before doing so put a radiator flush in the expansion bottle.ran the car for about 20 miles then drain it.refill with 50/50 anti freeze mix.put your heating on full to bleed out the air .ran the engine till water getting hot .then refit the expanion bottle cap.
You could have a slow leak somewhere near the engine or exhaust and when it does leak it just hits the hot part and burns away before it hit the ground. Your best bet is to get/rent a cooling system pressure tester. You can build up the pressure as if the vehicle is hot and since you are doig it when the engine is cold, you will be able to lovate the source of your leak. Like a freeze plug or even in your heater coil. That's what I would suggest. Hope this helps.
you can buy cooling system flush chemical at a store and do it at home.you will have to drain the cooling system into a drain bucket due to epa laws.then install the flush chemical and fill the system with water run the car to get it hot then drain the system again.refill with water again and repeat without the chemical to get as much of the chemical and coolant out of the system.then do a final drain and fill with coolant.it should hold about 2 jugs of anti-freeze don`t forget to do the overflow bottle as well.then you can have the anti-freeze checked for cold weather protection.
hi, if your 100% sure that their is no coolant leaking onto the floor then look inside the car where the drivers and passenger feet are if the floor is wet then this means the heater rad is leaking and needs replacing if its dry then this could be a more serious problem now what you need to do is check your oil pull the oil stick out and check for signs of water if water is present then it will look a grey color and this would mean head gasket failure if how ever the oil level is ok and the color is normal then this could indicate that the head gasket has gone and the coolant is being burned out with the engine gasses, you need to get a compression test done and possibly a sniff test to test the coolant for signs of gasses from the engine.
Let me know how you get on or if you need further assistance ok
If you are changing the bottle then you may need to empty the cooling system,change the bottle and refill and make sure you add anything that is needed with it,(like anti freeze if applicable).Once new bottle fitted you will need to fill it with water and preferably from a hose...then you will need to make sure there is no air inside the system..This should solve your problem..
It would happen only once in a while likely because the overflow bottle doesn't always fill to the point of where the leak is located. It would be very easy to unbolt the bottle and fill it with water to find the leak and patch it up.
hi get it prussure tested if you are correct in saying there is no sign of a leak or signs of water in the exhaust then you will have a leak and what is happening is it is evaporating as it leaks hence on sign of leak usually theseleaks are found where hose are near something hot example exhaust manifold the pressure tester will make the leak visable yates210456
