Hey I was wondering if how I could fix my own radiator leak without taking it to the shop. What are some ways to stop the leak?
My car has 230000 miles.
My car has an automatic transmission.
Experienced mechanics share their insights in answering this question :
The radiator in your car is most likely leaking from one of the plastic tanks and not the aluminum core part of the radiator. The tanks on these radiators are not repairable and the radiator will most likely need to be replaced.
Your best bet is to replace it with an aftermarket one that will cost a lot less than the dealer one in most cases. The dealer one would most likely be of a higher quality but that is not always the case. In order to replace it yourself, you would have to know the proper procedures to replace the radiator and bleed the air out of the system properly. I recommend having a mechanic like one from YourMechanic come and check the system for you to replace the radiator and cap along with any needed hoses and clamps that are needed.

The most common reasons a Toyota Camry has a coolant leak are loose hose connections, a broken radiator, or a failed water pump.
Leakage from the bottom of the radiator often comes from your water pump, as this is where your water pump is. Corrosion or road debris can also damage your water pump. There are also hoses attached to your water pump; if a hose starts to loosen or detach completely, it`ll leak.
Get alert if you observe the temperature gauge creeping up in the red zone. But if you start to see steam or bubbles coming from your radiator, that`s a sure sign of a radiator leak. Park your car immediately to avoid engine damage. Once your vehicle cools, check the radiator coolant level to confirm a leak.
The average cost for a Toyota Camry Radiator Replacement is between $596 and $732. Labor costs are estimated between $233 and $294 while parts are priced between $363 and $438.
Corrosion within the radiator is one of the leading reasons that coolant leaks. As the tubes get older and weaker, you may get sediment or debris inside that causes a leak. The sealing gasket between the tank and the radiator can also wear out, and that could lead to a leak.
It may be a broken hose and/or a hole in the radiator. Solution: Check your hoses to see if any coolant is coming out. Replace the hose(s) if you notice coolant coming out of them. If you notice coolant leaking out of your thermostat that can be an easy fix.
You should know that the most popular—and easiest—way to fix a radiator leak is to use a stop-leak productOpens a new window that you simply pour into the radiator. For example, AlumAseal Radiator Stop Leak & ConditionerOpens a new window can quickly fill any small holes in the cooling system.

If coolant leaks, it`s the antifreeze you`ll notice because of its bright color. Radiator leak: A coolant leak may involve a leaky radiator, but the culprit could also be another part.
Driving with a radiator leak is a dangerous operation, as it will very likely cause your engine to overheat. If you are driving down the road and notice your engine is overheating, pull over immediately and let the vehicle cool down.
Depending on the severity of the leak, it can last from 10 to 50 thousand miles. In a severe case, the solution may not work at all. If your car is leaking, you should look for a better radiator repair solution.
Technically speaking yes you can use plain water in your cooling system but it isn`t recommended as a long term solution and certainly not in extreme weather conditions.
Antifreeze (aka coolant) is pumped through your vehicle`s engine as you drive, absorbing excess heat and exchanging it with the outside air. That means an antifreeze leak could cause the engine to overheat — and that can lead to major engine damage.
While driving with a coolant leak doesn`t pose an immediate threat to your well-being, we highly recommend that you avoid doing so. Driving a car that is leaking coolant can cause serious damage to your engine. Your engine can overheat, costing you big time.
The average cost to fix a leaking radiator is $340, with a range between $125 and $600. Your total cost will depend on a number of factors, such as the type of repair needed, the type of radiator you have and the materials required.
Depending on the cause of leakage, you may get away driving with a radiator leak for a short time. Eventually, the lack of coolant will cause your car to overheat – which may in turn precipitate damage to various engine bay components. That`s why it`s a good idea to stop and inspect the issue as soon as you notice it.

I have a leak in the coolant system that I have narrowed to I believe is the water inlet tube off of the lower radiator hose.
First off, I would say it would be best to pressure test the cooling system to verify where the coolant is coming from. With the complexity of repairs to the cooling system on this vehicle, it may be worth the time spent to pressure test the system before tackling the replacement. Now then, as far as replacing the o-ring seal on the water pump inlet tube, it should really only require the removal of the bypass hose, lower radiator hose, and the two (or three, depending on manufacturing changes) mounting bolts that hold the inlet tube to the block. I personally would go ahead and replace the tube while I was there, instead of just the o-ring. Granted, this doesn’t mention what it will take to get down to the inlet pipe, but this is all it should take once you have access to it. If this is something that you feel you could use a hand with, consult with a certified mechanic, like those available at YourMechanic.com.

If you have not done a job like this before you might want to consider watching a professional from YourMechanic do it for you, especially as the labor time is less than 1.5 hours so it’s pretty economical. The first order of business, of course, is to make sure that the upper hose is actually leaking and you don’t have a different issue such as a crack is the radiator itself where the hose attaches. Also, if that hose is leaking due to a break in aged rubber, the other "old" hoses should be inspected as well. A radiator hose replacement entails removing any plastic shields that prevent access to the hose(s). Then, you have to drain the coolant to a level below the lowest point that you will be working at. The hose clamps are removed and then you have to carefully "debond" the hose from the point it is attached to the tank. Over time, the rubber will bond really tightly to the radiator and you have to break the seal with damaging or severely scratching the radiator "nipple" (the part the hose slides over). Then you slip the new hose on (with clamps already loosely applied), apply the clamps and you are ready to refill. When refilling, you have to open the cooling system bleeder screws (if equipped) to ensure that air does not get trapped. Trapped air could cause the car to overheat as trapped air can block coolant flow.

Coolant leaks no matter how big or small should be addressed as soon as possible. As you noticed, the engine will run hot with a low coolant level. Even a minor leak can expand to a large or catastrophic leak with no warning. A minor repair now can turn into engine overheat and damage. The leak can be small enough now that it is burning away when contacting hot surfaces and not hitting the ground. If the radiator leaking is the cause of the coolant loss, then it should be replaced as soon as possible. The cooling system operates under pressure – usually 12-15 psi. A small leak can become a large leak because of the pressure. Have a certified technician address this as soon as possible. Do not use "coolant leak sealer" products as they are a temporary fix and can actually cause more damage by clogging small coolant passages and damage the water pump as well.
Have a leak from upper or lower radiator hose.
I would recommend looking at either hose to determine which hose the leak is coming from with the car running as this will pressurize the system and force water to the leaking point. Consider scheduling an appointment with one of our expert mechanics to come to your home or office to diagnose the leaking coolant issue and make necessary repairs.
water is leaking from my radiator. I have to put antifreeze every other day. I put stop leak but it did not work and my A/C stopped working
If you are losing coolant from your radiator, the radiator will need to be replaced in order to stop the leak. When your coolant level drops past a certain point, the air conditioning will no longer work because the engine is overheating. I would recommend having a qualified mechanic perform this service to prevent any possible problems during the repair as well as having a warranty to go along with the repair.
After the radiator is replaced, I would the recommend having a cooling system pressure test performed to ensure that there are no more leaks in your cooling system. Once it has been verified that the leak has been repaired, have the air bled from the cooling system because any air that is left in the cooling system will cause the vehicle to overheat.
There is no visible leak in radiator. But daily I have to pour 100ml coolant in radiator. Gasket also recently changed…
If you have to keep adding coolant daily and there are no external leaks, the only place for the coolant to go is in the engine. Check the oil to see if the oil is getting milky (looking like chocolate milk) indicating water is in the oil. If that is okay then the only other place is for the coolant to go into the combustion chamber. You stated you changed the head gasket. If your engine has overheated before and the head gasket blew, then you may have also cracked the cylinder head. Most of the time the head will crack between the valves in a coolant jacket, and if you did not have the head pressure tested, this may be the problem now. You can have the cooling system pressure tested and see if coolant gets into one of the engine cylinders. This is done by removing all the spark plugs and pressure testing until it loses pressure, then cranking the engine. Coolant will blow out of the cylinder that has a crack. If this is the problem then a replacement head will be needed.
I suggest you have this issue inspected by a qualified mechanic. A certified mobile mechanic from YourMechanic can visit your home or office to inspect your vehicle’s coolant issues.
Leaking from radiator drain plug petcock.
Hello. The only other solution you may have is to remove the petcock and install a bolt in its place with sealant. I do not recommend doing this though as it is not a permanent fix. If you want to repair it correctly, then the radiator needs to be replaced. This happens all of the time as these are not opened often.
If you want to have it replaced, consider YourMechanic, as a certified mechanic can come to your home or office to replace your radiator for you.
Using Bar’s stop leak for timing chain cover leak
Stop leak products are generally an amateur, unprofessional solution to a TECHNICAL problem. Factory Service Manuals do NOT recommend or specify stop leak products BECAUSE such products are NOT considered to be an acceptable repair strategy, save for rare exceptions. The composition of your question clearly indicates that you understand that the OPTIMAL solution is to just fix the gasket(s) and you are simply seeking a stop gap (no pun intended) measure while you prepare for that repair. After having researched these products for decades and having tried a few, talked to manufacturers and so forth, I would suggest that you just let the vehicle leak until it was repaired assuming of course that oil is NOT leaking onto a hot manifold thus creating fire and health hazards. Of course, it is best to just simply prioritize the repair and one possibility insofar as the cost, as well as the diagnosis, is to get a second opinion from YourMechanic.
