SOURCE: coolant leaking from what looks like a sensor above oil pan

:Most likely a freeze plug that's located in the side of the block..
it's a kind of 'weak link' so that it blows instead of the block cracking in a freeze.
They also rust out and leak.
very cheap to buy a replacement, but a little tough to install because they're a very tight fit and you'll need straight access to drive it in place....

SOURCE: I smell coolant and I

Typically a coolant light will not make the check engine light come on unless your overheating.

In this case, check your hoses that are running above the area you located the water for cracks and leaks. If they are all good then you will need to look at other candidates for causing this and none of them are very nice.

The water is circulated through the motor and Heads. If the hoses aren't leaking and you have no leaks on the water pump or mounting points for hoses on the motor that leaves the heads, head gasket, manifold gasket and cracks on any of those components or the motor itself. Your going to have to really get into that engine to locate the problem.

Start with the hoses. If they have never been replaced before now it's way past time to do so. make sure you include the hoses that run from the motor to the firewall that provide heat to the heater core.

SOURCE: coolant leaking from above front suspension

If it's from the front of the engine, the water pump may have failed. Check for water coming out from the bottom of the pump.
Was the overheating caused by low coolant level?
If not the pump, check your engine freeze plugs and hoses.

Our 2004 Isuzu Rodeo has developed a coolant leak. The leak appears to be around or above a little panel or plate immediately behind the oil pan? Cannot find any other source. What is inside the littl


You will have to clarify behind the oil pan. Front of engine towards fan. Rear of engine transmission side. Or above the pan towards engine side. If there is coolant leaking from behind the engine (between the engine and trans) and is not running down from above eg head gasket or hose connection, chances are good that there is a frost plug leaking on the rear of the block.

Tip

Basic checks:- if your vehicle is overheating.


The below checks are generally intended to apply to any make of motor vehicle, (even though, to post this tip I had to select a particular make & model).

Overheating may be caused by many things.
Ensure engine tune or other mechanical disfunction is not contributing to the overheat problem.
Ensure there are no vacuum leaks on the engine air induction system.
If gas bubbles are apparent in the coolant reservoir when the engine is running the motor it may have a blown headgasket - (if confirmation is required, go to a radiator shop and request a "combustion gas detector" test).

If no obvious mechanical problems exist I suggest you carry out the following checks:-
1) Check coolant system is not leaking fluid due cracked/perished hose or hose fitting, leaking water pump etc,
2) Check engine cooling fan/s are operating as required when engine temp rises above cut-in threshold - check fan control relay is ok,
3) Check for collapsing radiator hose on suction side of water-pump when motor revs raised above idle.
4) Check coolant reservoir pressure cap is serviceable,
5) Check coolant system is properly filled - carry out any bleed off procedure specified to clear any air locks- (ensure heater core coolant flow is turned on).
6) Check condition of radiator core:-
i) for blockage of air flow to (bugs/grass etc),
ii) for core internal blockage to coolant flow.
7) Check or replace the thermostat.

Where are the freeze plugs


iF THE ENGINE IS NOT LEAKING. THEN FREEZE PLUGS ARE NOT A WORRY, IF THEY ARE LEAKING LOOK FOR GREEN COOLANT ON THE SIDE OF THE ENGINE ABOVE THE OILPAN AND UNDER THE MANIFOLD.

Loss of coolant


You dont have an evaporation problem. You have a coolant leak in your recovery tank. Its located at about one inch above the bottom of your recovery tank.

Gets hot and low power


1 If engine overheating has occurred the coolant level will naturally be low due to expansion of the coolant from the extreme heat of the engine. This heat expansion forces coolant out of the radiator and coolant reservoir. To test for an engine coolant leak move the car to a dry smooth surface and allow the engine to cool. Remove the radiator cap and carefully (do not spill) add water until full, then re-install cap. Start engine and allow to run for about three to five minutes (do not allow to overheat) while the engine is running inspect the ground below the engine, if an engine coolant leak is present observe the location of the coolant drops, this will help determine where to start looking for the coolant leak (shut the engine off before inspecting). If no coolant is observed two additional checks are needed for a complete test. With the engine off remove the engine oil fill cap and turn it over, if a milky oil condensation is present the engine may have a failed cylinder head or intake manifold gasket allowing coolant to leak internally. To inspect engine gaskets disassembly is required. Next, the car heater core must be inspected; the quickest way to check the heater core condition without removal the heater core is to inspect the passenger's side foot well compartment carpet for the presences of coolant. If coolant is present the heater core has failed and must be replaced or repaired. After necessary repairs have been made refill the cooling system with manufacturers recommended engine coolant and recheck operation.
2 Inspect Engine Cooling Fan Clutch or Electric Fan Operation
3. check water pump

Coolant is leaking ,i have to fill it everyday.hardly any heat. what can i do? it seems like its shooting the coolant out somewhere on the right side of the motor.


It's probably the waterpump, it's right where you describe. They are pretty cheap and easy to do so even if you have a shop do it, it should not cost that much. Have it repaired before the engine is damaged from over-heating.

My mini is using alot of coolant we think the thermostat is blocked, its pressuerising it back through the resevoir


Most common coolant leak is from the thermostat housing seal. Replace seal or housing and bleed properly.
Loosen plastic bleed screw on pipe above fan belt. Fill coolant via pressure cap ( right had side of engine....not expansion bottle) tighten once coolant free of air is seen. Run engine, loosen other plastic bleed screw on heater hose ( towards bulkhead ) and retighten once coolant runs free of air. Top up via cap again, run engine at 2500 rpm for 3 minutes with heater on ...should be very warm now. Once cool, check level and top up as required.

Need to add coolant to my bmw 750li. What type and in what ratio should I mix with water?


Hello,


I am writing to tell you about a new BREAKTHROUGH method for repairing a leaking Coolant Transfer Pipe in the BMW N62 V8 engine block using the BimmerFix Stint. The N62 V8 is a popular BMW engine that was used from 2002 thru 2010, in such fabulous vehicles as the BMW 735i, 740i, 745i, 750i & Li, 645Ci, 650i, 540i, 545i, 550i, and the X5 SUV.


Located deep inside of this BMW N62 engine is a Coolant Transfer Pipe, which carries antifreeze from the Water Pump to cooling chambers within the engine. However, the Front Seal on this Cooling Tube can fail in as little as 40,000 miles, and start leaking antifreeze from the engine block, through a weep hole in the Timing Chain Cover. When this happens, the car will lose antifreeze from the engine, and the engine will overheat.


In the past, this has been a very expensive repair because it required disassembly of the engine, in order to access the leaking Cooling Pipe Seal. The original method of replacing the crossover Coolant Transfer Pipe required the removal of the Timing Chain Cover. This repair could cost $6,000 or more at the BMW Dealer.


Then, an after-market Collapsible Coolant Pipe was developed to save time and money on this repair. This Collapsible Coolant Pipe method involves removing the Intake Manifold, cutting out the old Coolant Pipe and installing the after-market Collapsible Coolant Pipe. But even this method required many hours of shop labor and expensive parts and supplies. The repair bill for this method can still cost between $1,500.00 and $2,500.00 to remove the Intake Manifold, cut out the old Coolant Pipe and install the new Collapsible Coolant Pipe.


However, BimmerFix Products Co. has discovered a BREAKTHROUGH system to stop the leak! The BimmerFix method is much faster and less expensive than these old methods. This simple, yet durable and long lasting method inserts the BimmerFix Stint into the leaking crossover cooling tube, through the Timing Chain Cover. The thin aluminum sleeve creates a long lasting repair that is much easier and less expensive to install than the old repair methods.


The new BimmerFix Stint will stop the Coolant Pipe leak, and only requires the removal of the Water Pump. This new patent protected invention can save YOU or your customer's time, hassle, and thousands of dollars. It works or your money back!

We have a 2000 deville that started leaking coolant. we replaced the thermastat and it continues to leak coolant. it wont overheat as long as we keep the coolant in it. it leaks alot more when the car is...


check condition of radiator,radiator & heater hoses,look for spots wet w/ coolant.look more or less straight up above where coolant puddles on ground.engine block is equipped w/'freeze plugs' that sometimes corrode & leak.washing suspected area of leak with an engine degreaser product may aid in locating source of leak.
