How to know if the head gasket or water pump leaks?
The antifreeze level should be approximately one inch from the top of the radiator. Add antifreeze if the level is low, then install the radiator cap. Drive the vehicle until the engine is at normal operating temperature, then park the vehicle and allow the engine to cool.
Can a water pump leak cause a radiator to overheat?
by John Stevens J.D. The extend of the damage caused by an antifreeze leak depends on where the leak is coming from. If the leak comes from the water pump, the problem is more of an inconvenience rather than a major undertaking, as the radiator will have to be periodically replenished with antifreeze to prevent the engine from overheating.
What happens if you have a coolant leak in your car?
If your car is leaking coolant, it will run normally until the coolant level gets too low. Once it is low, there will not be enough coolant to keep your engine at the normal operating temperature and the engine will overheat. If your engine overheats, it can cause significant damage to the block, heads and other components.
What to do if your water pump is leaking?
If the leak persists, the bearing in the water pump is likely to be defective and the water pump must be replaced. Attach a cooling system pressure pump to the radiator cap opening on the radiator . The pump features a single hose and a gauge. The end of the hose attaches to a metal fitting, which looks similar to a radiator cap.

When to replace the head gasket on a car?
If the needle fluctuates rapidly, the cylinder head gasket is defective and must be replaced. If the engine is equipped with two cylinder heads, it will be necessary to determine which of the two head gaskets is defective. Remove one spark plug wire at a time from its spark plug while monitoring the needle on the pressure gauge.

How much does a head gasket replacement cost?
The labor time to replace the cylinder head is 14.8 hours. This engine uses a timing chain running overhead cams on a conventional inline four-cylinder engine. An Apex head gasket cost (kit) would be about $86. With normal machine shop and fluid costs, this takes the job about $1906 to complete.
What happens when you replace your water pump?
Overheating after replacing water pump, thermostat and co… Q: Overheating after replacing water pump, thermostat and coolant temp.

Why is my water pump and thermostat not working?
The radiator, water pump, and thermostat are definite possibilities, but there are a few others that are possible also. A faulty cooling fan is the first thing that comes to mind, but it could also be a head gasket issue, clogged coolant passages inside the engine, or faulty radiator hoses.

What should I do if my head gasket fails?
Head gasket failures are usually the result of an engine overheating, so the best way to prevent a problem is to ensure your cooling system is in good condition. Ensure the system has no leaks, the radiator is working efficiently and the coolant is topped up to the correct level.
How long does it take to replace a head gasket?
Sealers also have a tendency to block small coolant passages, so you could end up with more blockage problems. How long does it take to fix a head gasket? Replacing the gasket can take anything from six hours to a few days, depending on the severity of the failure.
Where does the head gasket go in an engine?
The bottom of the engine is much larger by volume, and is where the cylinders and pistons that convert fuel into forward motion live. For proper engine function, there must be an airtight seal between these two sections. Your head gasket ensures that seal is maintained, but after years of wear and use, gaskets can dry out, crack and fail.
Do you need to put gasket sealer on water pump?
Water pump manufacturers do NOT recommend applying RTV or any gasket sealer unless specifically specified. If the gasket won’t stay in place, wet it with fresh coolant.
Is it OK to put RTV on water pump gasket?
Excessive RTV that seeps into the contact area with the coolant will eventually break off and clog radiator and heater core passages, reducing engine cooling and heater operation. Water pump manufacturers do NOT recommend applying RTV or any gasket sealer unless specifically specified. If the gasket won’t stay in place, wet it with fresh coolant.
What should I do if I have a head gasket leak?
Otherwise order OEM gaskets and stainless bolts, find an engine machinist in your area and have them cleaned and inspected for flatness and cracks and you may need him to remove a couple broken manifold bolts. Flatness can usually be fixed, cracks can’t. Be prepared for potentially buying new/remanufactured heads.
Is there a test for a blown head gasket?
However, coolant leaking internally can be more difficult to diagnose and usually means a blown head gasket. If your car is overheating and the coolant levels are decreasing, there is a radiator cap test, or what is sometimes referred to as a champagne test, you can administer.
Can a Delco tablet seal a head gasket leak?
920 miles or so)…. if your leak is small enough it will seal that leak. The Ac Delco tablets will not clog any heater core tubes !! You must be logged in to reply to this topic.
Is the water pump leaking from the head gasket?
I dried off the top of the block right behind the water pump where it looked damp and then started the truck and could see it get damp again over a couple minute time frame of the truck running. I did it again just to confirm. It is in fact leaking from the head gasket, not the water pump.

If you decide to replace a gasket, in the absence of definitive proof of a head gasket problem, suggest to start with the intake manifold gasket first. Water out the tailpipe and white smoke isn’t a foolproof diagnosis for a head gasket problem. I checked the dip stick and the oil is still as clean as when i changed it about a month ago.
How to repair a leaking intake manifold gasket?
Before you begin the tear-down, you will need to do some preliminary research. First, go to the auto parts store and buy the repair manual for your make and model car. Next, pick up a few car magazines. They usually have articles on replacing intake manifold gaskets and rebuilding cylinder heads.
What are the symptoms of a bad water pump?
1. Coolant leak at the front-center of your car. The water pump is comprised of multiple gaskets and seals that keep coolant contained and ensure that consistent flow of coolant is delivered from the radiator to the engine. Eventually, these gaskets and seals will wear out, dry up, crack or break entirely.
Is it easy to fix a water pump leak?
Fixing a water pump leak may sound simple when you first see drips of coolant under your car but depending on the water pump location it could be a relatively difficult job.

If possible flip the breaker that controls your pump or if the smoke is just coming from the actual pump, unplug it immediately. Smoke means you are at risk for starting a fire – or one has already started. While this may seem scary it is important to never throw water on anything that uses electricity to put out a fire.
How to tell if your cooling system head gasket is blown?
Test to see if the head gasket is blown the cooling system will need to be pressurized using a cooling system pressure tester to put pressure on the cooling system to see if it holds pressure. If it does not hold pressure and no external leaks are found then the head gasket is leaking.

Why is my water pump leaking after 140k miles?
At 140K miles, the water pump seal could be worn out and started to leak. My 3.4L van just had the water pump replaced couple weeks ago. The coolant sprayed out on the side near water pump. If you hear squealing sound (coolant on the belt) when first started the car, then it is indicative of water pump leaking.
Why is my water pump leaking coolant on my minivan?
If you hear squealing sound (coolant on the belt) when first started the car, then it is indicative of water pump leaking. Water pump fix is cheaper than the gasket replacement (intake gasket for the notorious 3.4L V6, especially on GM minivan: virtually every van has this gasket problem). So you’re saying that the head gasket isn’t the problem?
How much does it cost to repair a blown head gasket?
What may start as a faulty thermostat or leaking hose, which can be easily replaced, may end in a blown head gasket and a potential repair bill in the $1000’s. The good news is that there is often time the remedy the situation before permanent damage occurs.
