Installation is almost always reverse of removal for working on cars. I would recommend retracing your steps to figure out if you installed something out of order or maybe skipped a step. There are also repair manuals available at your local auto parts stores that will give you a step by step procedure for replacing parts such as this. In order to install a water pump you usually need to line up the gasket with the bolt holes, hand tighten all the bolts that mount the water pump to the engine and then torque them to the correct specification. After this is done, you can reinstall anything that was removed in order to access the water pump such as the radiator fan, fan shroud, etc. If you find you are needing further "in person" assistance, a certified technician from YourMechanic would be happy to help you with the replacement of your water pump.

The average cost for a Toyota Tundra Water Pump Replacement is between $513 and $635. Labor costs are estimated between $337 and $426 while parts are priced between $176 and $210.
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.
They can go as long as 100,000 miles although it`s always a good idea to change it before then. Belt failure can cause extensive damage to the valves, pistons and other internal parts of the engine. The cost of changing the timing belt is a bargain when you consider the cost to replace the entire engine.
When to replace the timing belt? Every 60k-90k miles. If an engine is equipped with a timing belt, the timing belt must be replaced at the service interval specified by the vehicle manufacturer regardless of whether or not any problem is visible, typically in the range of 60,000 to 90,000 miles.
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.
Your shop is correct that the labor time to replace the water pump is about five hours.
Many reputable automotive sources have reported on the lifespan of a Toyota Tundra, and from the overall analysis, you can expect a Tundra to last between 150,000 to 250,000 miles on average. Reaching 300,000 miles is not out of the norm, if the truck is well-maintained.
Toyota Tundra
First Generation (2000–2006)
It was larger than the T100, but shared its 3.4-liter V-6 as the base engine from 2000-2004.
No timing belt will give an increase in performance – it`s just not possible. Its main job is to keep the timing in check. Having your timing belt replaced and noticing an increase in performance is just a mix of the engine operating at peak efficiency and a good hit of placebo effect thrown in for good measure!
If your belt has been damaged, you will most likely hear the starter engage when you turn your key but the engine will not ignite. In case your timing belt is broken inside, it won`t be possible for your engine to start working, since your timing belt is what engages your crank and camshaft, it won`t turn over.
The expected lifespan of a water pump is 60,000 miles to 90,000 miles, but many can last longer than that. Usually, once your car has reached the coveted 100,000 miles, you can plan on the need for a pump replacement soon.
Water pumps are driven by the timing belt and usually last around 100,000-150,000 kilometres. Most manufacturers do a good job of making quality pumps, so it is fairly unlikely that you`ll run into trouble with one.
Fuel Savings and Noise Reduction
While the amount of the efficiency loss is small, it`s fair to say that replacing an older water pump can lead to a small increase in engine efficiency and fuel economy. A new water pump can also reduce engine noise. Again, older pumps likely have a bearing with some wear and tear.
The expected lifespan of a water pump is 60,000 miles to 90,000 miles, but many can last longer than that. Usually, once your car has reached the coveted 100,000 miles, you can plan on the need for a pump replacement soon.
You should replace the water pump after 60,000 to 100,000 miles for most modern vehicles. If your car is new, there is no need to worry about it. However, if you drive an older car, be sure to mention it to your mechanic.
Water pump replacement after coming loose?
ANSWER : Water pumps do NOT get loose on an engine excepting an unusual circumstance where the pump was improperly installed. So, the mechanic might be referring, in your circumstance, to a seized water pump or a situation where the water pump pulley and/or pump impeller have come loose. Certainly, if the water pump pulley is loose or the pump impeller has failed, the pump is not re-usable and must be replaced. However, if the pump itself, that is the aluminum pump housing, was loose (i.e., the bolts holding the pump to the engine block were loose) unless it is a relatively new Toyota pump, it is wise to replace it simply because the pump shaft seal does not last forever and if the pump has any significant number of miles on it will be cheaper in the long run to just replace it now when the mechanic has to already go in there anyway to re-install it. If you are re-using a pump, you have to remove it to re-gasket it and re-install it so better to just install a new pump and save yourself the possibility of the used part failing "soon". As far as engine cooling system thermostats are concerned, if you install a new water pump, the best practice is to install a brand new thermostat (use Toyota OEM ONLY; save yourself a headache and do NOT use aftermarket) because the engine thermostat performs a critical function in terms of optimizing and regulating engine operating temperature. Thermostats do not last forever and when they fail they often cause engine overheating which is VERY bad. The reason the best practice is to replace the thermostat when the mechanic is already in there, and the cooling system is already drained, is the thermostat housing is often adjacent to the pump and so it is also efficient and economical to replace it. Thermostats are not expensive: the Toyota OEM thermostat might be around $25 with a mechanic’s discount. As far as this job being costly, as you noted in your question, yes if you use a shop, or worse a "dealer" where the mark ups are huge, you can be sure you won’t be eating lunch for the next month once you have the job done. However, in your circumstance you have a choice: a water pump and thermostat replacement, plus a new serpentine belt, is a relatively easy task on a vehicle such as yours and so is an ideal in the field, mobile job. You can not only save money but get personalized service if you replace the water pump through YourMechanic and the money you save can be put toward OEM parts which a mechanic can get for you typically at a 25% discount off the dealer list price. If you do the job and you want the fewest headaches, but the water pump, thermostat, and belt from a Toyota dealer. Finally, IF the pump was in fact loose, the REASON it was loose has to be investigated. In particular, a loose assembly raises the possibility of stripped internal threads in the block thus causing the bolts to eventually come loose. So, if in your case, there were loose bolts, the internal threads have to be carefully inspected and repaired if necessary, otherwise you will be completely wasting your money on the repair because the pump WILL come loose again.
