Water pump leaking and no pressure in the engine head
Yesterday, the engine and VHC lights came on. Later, while driving to the dealership, the lights went off, but then back on. The mechanic told me that the engine light is due to the water pump leaking. Later, he called and said that the engine wouldn't start and they wanted to keep it to check out more. Next, he called to say that there wasn't any pressure in the engine head. He called Lexus since this is so expensive, but they wouldn't help. During a previous maintenance I had an oil change, fluid levels checked, brakes were checked, etc. Any advice you can give me would be very a
Experienced mechanics share their insights in answering this question :
You did not mention if the engine was having any running issues other than the two lights coming on. Without knowing the codes that were stored and the actual problems causing the cylinder head to have no compression or coolant leaks, I cannot know the problem they encountered. I would recommend calling and talking to Lexus yourself to see if they can help you. They may help you pay for the repair if you call.
How to Identify and Fix Common car Problems ?

Check Engine Light – A water pump itself will not cause the check engine light to come on. The reason that your check engine light comes on is that the water pump affects your engine. Without your water pump, your check engine light will come on because your engine will slowly overheat.
If a water pumping is leaking it cannot efficiently move coolant around the engine. If that happens the engine will get hotter and will eventually overheat. At first the temperature gauge will hit the red, then you`ll start seeing steam from under the hood.
The oil leak from the valve cover is leaking down onto the water pump causing the water pump seal to swell with oil causing the water pump to leak coolant. The oil leak from the valve cover must be repaired before the coolant leak can be resolved.
If the water pump is not circulating coolant properly, it can cause the engine to overheat. This can lead to serious engine damage if not fixed in a timely manner, so it`s important to keep an eye on your vehicle`s temperature gauge and keep an eye out for any warning signs of overheating.
Warning. If the water pump is leaking from the body of the water pump, you must return the pump to the vendor for servicing. There is no safe way of fixing a leaking water pump body.
The most common is improper lubrication when the incorrect lubricant is used or not enough is applied. Bearings also fail in extreme temperatures. Another cause of failure is bearing overload, e.g., a pump cavitating from lacking the proper flow will increase pressure on the impeller`s front.
Water pumps can leak from 2 different places; the shaft seal or the water pump gasket. If the water pump bearings are starting to wear out they will allow the shaft to wobble and coolant will leak out.
Why You Should Never Replace A Water Pump Gasket Alone. It is possible a water pump gasket can leak prior to a water pump failure. However, it`s never a good idea to replace only the gasket. As described, the pump may already be failing by the time the gasket leaks.
With the engine off, open your hood and locate the water pump pulley. With gloves on, grab it and wiggle it back and forth. There should be no movement, if there is, this along with the noise is a good indication you may have a water pump problem.
If the water pump fails, it is unable to circulate the coolant around the engine. It causes the engine to overheat as a consequence. If the engine overheats, it will likely cause additional damage, such as blown head gaskets, cracked cylinder heads, damaged rings, and burnt pistons.
Without a correctly running water pump, your engine will overheat in the summer or freeze in the winter. This can not only cause damage to the gaskets, cylinder heads and pistons, it often results in total engine failure.
The water pump is one of the vehicle components that may never require replacement if your vehicle is well-taken care of. You can own a car for over 15 years and never have to replace the water pump. That`s not to say that it can`t develop a problem.
If you want to avoid expensive mechanic bills but don`t have the technical knowledge or experience needed to resolve a leaking water pump in any other way, K-Seal is the option for you – it can fix most leaks in the water pump casing and in the seals.
The whole purpose of pump seals – either mechanical seals or packing seals – is to contain the pressure of the pumping process and withstand the friction of the pump shaft rotating to prevent the pump from leaking.
When water pumps go bad, it causes your engine to overheat—and that leads to all sorts of trouble. While water pumps are designed to last a vehicle`s lifetime, it`s entirely possible for them to fail before that mark.
Yellow or Green Fluid
Typically, this means that you`ve got a leak in your radiator, your water pump, or any of the hoses that carry coolant.
Kitchen and Bathroom Faucets
Faucets are arguably the most common place for water leaks to happen. While that steady drip, drip, drip might seem like a simple annoyance, taken together those droplets could represent a significant increase in your water bill.
So when the water pump must be replaced, it is a good idea to go ahead and also replace the timing belt, timing belt tensioner and idler pulleys.
Overheating would be a first sign. White smoke out your tail pipe indicates a blown head gasket. Water or antifreeze in your engine oil or on your dipstick is another sign.
Whining or Groaning Noise
A whining or groaning noise usually means that either a drive belt is loose, or the water pump pulley is bad. It may surprise your customer that a pulley could fail, but it does occasionally happen. Pulleys have been known to fail due to rust, which can cause cracking between their bolt holes.
What is P06DD? P06DD is a diagnostic trouble code (DTC) defined as “Engine Oil Pressure Control Circuit Stuck Off.” This trouble code means that your vehicle`s engine oil pressure sensor is signaling the Powertrain Control Module (PCM) that the oil pressure is too low — and affecting the dual stage oil pump.
Water pumps are designed to last at least 100,000 miles, however, if your water pump fails, you should replace it with a high-quality original-equipment level unit. Less expensive replacement pumps are available, but they might only have a service life of 30,000 miles.
Debris blocking the suction strainer or foot valve is the most common cause. A blockage in the intake line can cause the water in the pump casing to overheat and literally boil out of the casing causing the pump to lose prime.

My water pump is leaking but I replaced timing belt and pump a year ago. Can I just replace the water pump this time?
ANSWER : Hello. You can just replace the water pump in this case. Although, the cost of just the timing belt is fairly negligible in comparison to the total labor of the job. My estimator says the water pump is a 6.5 hour job. Multiply that by whatever the shop rate is and you have the total labor without parts. You end up saving about $100 or less on parts if you only replace the pump.
The deciding factor will be the condition of the timing belt. If it has problems, you won’t be saving yourself any money by reusing it. In addition, there are seals and pulleys that may need to be replaced as well.
Assuming all the related parts were replaced the first time around, there isn’t a reason you can’t reuse them. I would say you should weigh the savings of reusing them against the actual condition of the parts. This is best determined after a complete disassembly. Keep in mind, time estimates will vary a bit depending on many factors. Either way, the labor is the largest cost.

Can a jeep run and drive without a water pump??
ANSWER : Driving or running the engine without the water pump working to circulate the coolant through the motor will cause the motor to overheat and may damage the engine costing thousands of dollars versus using a tow truck to take the vehicle to the shop that will cost a lot less. I would not recommend running the engine more than a few minutes at a time or you will overheat it.

Is leaking water but the thermostat the water pump and the heater core is good but it’s slowly dripping water onto the ground
ANSWER : Based on your description, you may have a small leak somewhere in the connections to your radiator, water pump or to your engine. Often times water leaks start out small and develop over time increasing and decreasing depending on the temperature of the water. I would recommend having an expert from YourMechanic come to your home to diagnose and repair your cooling system.

Engine rattled, something fell out, and engine died
ANSWER : Hello. I would go ahead and follow the dealership’s recommendation and have the updated water pump installed. I would also recommend having the belts, and any other pulleys, replaced if possible. If the vehicle is still under factory warranty then the dealership is not liable for any repairs, however I would talk to them about the issue to see if they may be able to help. If not, have the water pump and associated components replaced by a certified technician from YourMechanic as soon as possible, as the vehicle cannot function without these components.

My engine blew out due to my water pump leaking…i didnt have no problems with my car over heating, no steam, running weird,
ANSWER : It is quite likely that when the car was hit, the radiator may have been punctured which would have caused a lot of the coolant to leak out of the vehicle.
If the water pump failed or if it were low on coolant, there would have been overheating indications on in the dash, so you should have had some kind of warning either way that the coolant level was low.
If you’d like to get this fixed, consider YourMechanic, as one of our mobile technicians can come diagnose the leak firsthand and help address any other potential issues.

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.
ANSWER : 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.

Leaking water pump new Honda pump at 134000!! Any suggestions besides changing the pump
ANSWER : I never recommend using a "fix-in-a-can" or a "stop leak," as this can add sludge to your engine. You may just have a faulty gasket for the water pump or even a faulty water pump. In either scenario, the valve cover and timing covers have to be removed to determine the cause of the leak. It may be a simple gasket problem or an issue with installation. I would definitely not recommend using stop leak as it will sludge your engine.
I would recommend a pressure test and a visual inspection of the leak once the covers are removed.
