Step 1 has to be find out where the leak is. Possibly a stone hit or damage by frost (Have you checked your antifreeze levels?) Also, if this rad is one with a removable core that is effectively clamped into a plastic top and bottom tank, the fixings may be loose or damaged.

Radiator repairs are always a nightmare and typically they need to be done professionally. For the sake of saving a shed load of cash on a new radiator, I would suggest spending a small amount of cash on a bottle of radiator leak repair from your local auto factors. "Bars Leaks" or "Radweld" or similar. Check the bottle (or ask advice at the counter if they are knowledgeable) and ensure that the product is compatible with your system as there can be dependancies sich as aluminium heads that require different products. Also, I've got to say that my experience of these products is the higher up the radiator they are, the less well they work because they require the fluid mixed with the coolant to leak out of the breach and clog it up (a bit like when you bleed and the bleeding stops and a scab forms). The higher up the rad, the less exposure to the repair fluid and the less effective it is. All you can do is try.

This radiator is plastic and aluminum it there is small leak on the plastic part it can be stopped with an EPOXY. However you must locate the source of this leak first so that you can solve it. If it leaking from the fins/vains on the radiator I would recommend that you replace radiator very simple to do. Good luck and thanks for using FIX YA

Loses water from resevoir but not from radiator


So the level keeps dropping in the reservoir? If you have to keep adding coolant to the reservoir, the system is leaking or losing coolant somewhere. Have the system pressure tested to find the leak. Is the reservoir itself leaking? When the level gets low enough, first the reservoir will go dry, then the radiator level will start to drop.
Here's how the reservoir works: coolant is under pressure from the radiator cap seal. As coolant heats up from hot engine, it expands, and pressure forces the radiator cap seal up, coolant is forced into the reservoir-remember the hot mark on the reservoir? When car is shut off, coolant contracts, creating a vacuum in top of radiator. This vacuum works to suction coolant back from reservoir into the radiator, keeping the radiator topped up, and coolant should now be at the lower cold mark on the reservoir. It is a closed, sealed system. The only loss of coolant will be a very small amount of evaporation from the reservoir. If coolant level keeps dropping, there is a leak somewhere.

Why is gearbox oil getting into rhe radiator on my jeep grand cherokee 2003


it is probably not gearbox oil. it is probably transmission fluid because it travels through the radiator cooling tanks. the cooling tanks may have a leak causeing the fluids to leak into the radiator.

Why does the motor overheat and looses water


You have a leak somewhere is the obvious answer, the hard part is finding the leak, it could be a hole in the rad or a split in a hose somewhere, I suggest you drive the car for 15 mins, park it up, pop the hood/bonnet and see if you can see a leak, then look under the engine ( on the floor ) and see if there are any leaks on the floor. you can get solutions you put in the radiator to fix radiator leaks, but a hose, could burst and cause a massive engine failure, hoses need to be replaced.

Radiator toyota camry 1998 v6


You may have

- a coolant leak somewhere, comes out when the engine heats up and pressurises the radiator. Camrys do develop a crack in the plastic radiator top tank, which can be hard to see if on a seam. Another place which leaks is under the intake manifold, which is not visible. There is a test, called a "leak-down" test

- thermostat stuck closed, preventing coolant circulation

- a leak through a head gasket from a combustion chamber to the coolant jacket. This will quickly cause overheating, and sometimes causes white bubbles in the radiator neck, like dry ice. There is a test kit available for gases in the coolant.

2001 Ford Escape. Coolant leaking from somewhere. Went through bottle of coolant in 2 days.


If there is no sign of a leak you need to test for cylinder head leaks.
Warm up the engine and remove the radiator cap. Top up the water to the neck of the filler. Squeeze the top hose a couple of times to shift any air in the top tank of the radiator. Run the engine on idle and check for bubbles it the radiator, keep it topped up to the neck. Bubbles showing means you have a head gasket problem.

My 1999 Alero must have a leak somewhere because the thermostat gauge rises every few days. I put coolant in it at least 1 a week. I had a new water pump and thermostat put on it, but it is still...


CHECK AROUND WATER PUMP AREA.AND THERMOSTAT HOUSING FOR LEAKS.THE MECHANIC WHO PUT THE WATER PUMP ON MAY FORGOT TO PUT SEALANT ON BOTH SIDES OF THE WATER PUMP GASKET CAUSING LEAKS.LOOK AROUND THERMOSTAT HOUSING FOR LEAKING.IF THERMOSTAT SEAL WAS DAMAGE DURING INSTALLATION IT WILL CAUSE LEAKING.IF ALL LOOKS GOOD CHECK FOR COOLANT LEAKS AROUND RADIATOR .CHECK RADIATOR TOP AND BOTTOM HOSES FOR LEAKS AND CHECK HEATER PIPES AND HEATER CORES HOSES FOR LEAKS.IF ALL HOSES GOOD.CHECK FOR LEAKING CORE PLUGS.

Radiator leaks somewhere at the top and wondering if it can be patched. obviously depends on where and how big of a leak, but is it worth trying to patch or just replace it


Hi!!

To fix your 13 year old radiator at a shop will cost you $80-$100, To get a new aftermarket radiator at an AutoParts store will run about $185 + tax. If your leak is not too big and can wait a couple of days, Radiators.com have one for about $140. Honestly, I would go for one of the new ones!!

Don't forget to rate this answer, GOOD LUCK.

Strange Coolant leak


this most likely means that you have a leak in a hose somewhere between your engine and the radiator, when you open up the rad cap it lets the leak breath causing it to gush out, go to napa and buy a replacement radiator hose it shouldn't cost but a few dollars and that should fix your problem.
