I have had to replace a pinched lower coolant pump hose

ANSWER : Hello – if the hose is becoming pinched, it would seem that you are getting an incorrect part, or the engine strut or mounts are deteriorated enough to allow engine twist, distorting the hose. The leak is likely from the o-ring on the end of the metal tube which goes into the water pump housing, not the hose itself. This o-ring becomes brittle over time, and leaks down the pipe to the lower hose you describe. I would recommend having a Coolant is Leaking Service completed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, confirm this diagnosis, give you an accurate assessment of damage and cost estimate for repairs.

ANSWER : Hi there. For the coolant light to go out, you would need to have the coolant between the low line and the full line for the light to go out. If the coolant is low and keeps on being low, then look for any signs of coolant leaks. You may have to use a coolant pressure tester to pressurize the reservoir to allow the leak to be found.

If you need further assistance with the coolant being low and the warning light being on, then seek out a professional, such as one from Your Mechanic, to help you.

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.

If you would like to have the water pump replaced, a certified professional from YourMechanic can come to your car’s location to perform this service at your convenience.

ANSWER : Hello. The most common cause of a random coolant loss on this vehicle is a leaking intake manifold gasket. It commonly starts leaking coolant into the engine, which will be burnt off or will leak externally. I typically do a pressure test and a dye test on the system first to see if I can locate an external leak. If nothing is found, then I do a block test to make sure that there is not a head gasket issue. If nothing shows up there, then I replace the intake gaskets. If you need to have this done, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose the coolant leak and replace the intake gaskets if necessary.

ANSWER : Hi there. It really depends on who provided you with this diagnosis as to how long the repairs would take to complete. In regards to not including the seals listed at the bottom, this is not advised. The seals protect the components from leaking and will also reduce the potential of overheating on your vehicle.

ANSWER : Hi there. The hose that you are describing sounds like the heater core by-pass hose. If the hose is short and straight, then it would be the heater by-pass hose. The heater by-pass hose it to by-pass the heating system until the engine is hot. If you need further assistance with your coolant hoses, then seek out a professional, such as one from Your Mechanic, to help you.

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.

ANSWER : Hello there, 45,000 miles is a short lifespan for a water pump on your 2000 Honda Odyssey. There are a few reasons the water pump will need to be replaced, such as a pump bearing failure, water pump seal leak, or rust/contamination damaging the pump. Faults such as rust or particles in the cooling system are formed in the cooling system over time and the parts break down, or regular coolant flushes are not performed. These particles can cause the pump to fail prematurely. It would be a good idea to ask why the water pump needs to be replaced or take note of any symptoms you are experiencing with the car before moving forward with this. If you would like to have an expert give you a second opinion on this, a certified technician from YourMechanic can come to your location to inspect the car and replace the water pump if necessary.
