Water pump failing!

I use this site a lot for finding part numbers. If you use your Vin that will be the easiest and leave no doubts. I'm linking what I'm guessing would be the section applicable to your 2003 ext cab v6auto.

Thank you ”Cruiserguy” that’ll be very helpful! Thanks for the sound advice “2JHilux” and everyone else too.

 

Finally got done with truck today! Been waiting on parts for weeks from OEMgenuineparts. Not their fault I guess the world is a screwed up mess with this virus crap. Anyway it’s done and was good to hear it willingly start up. New water pump, timing belt, cam seals, crank seal, cam sensor, crank sensor, Harmonic balancer, accessory belts, reshimmed exhaust valves, stripped/painted valve covers, new valve cover gaskets and new hoses including oil coolant hoses. Thanks for all your help and I’m glad it’s done!

 

Nice work hermano.
Sure does give the most peace of mind when you do your own work and then you know exactly what was done and how it was done

 

I agree.. and I was thanking God that it didn’t catch on fire! I was ready if it did.

Was a little concerned about fuel rail.

 

until you try to do your own brakes that one time and they malfunction in a bad way coz you just never know

 

Yeah man that is true, crap happens and you just never know what can happen

 

I drove my truck brand new out of the dealer and since then I have not brought it back except to buy parts. The only time I had a shop do something to it was to replace the tires, align the front end, and replace the steering gear. Everything else (front axle replace, shock replace, injector replace, water pump/timing belt replace, brake rebuild, fluid changes) I did myself.

If I can do it, so can you if you have the tools!

 

i am like the total opposite of you lol
my truck had been 100% dealer serviced with just a couple of batteries from sears and tires at DT
i always got quality hometown family-owned service at a reasonable price until the 2nd gens came along and threw the whole routine maintenance packages i did right out the window and stuffed my old truck into the ditch
and then they started incorporating around here into the big conglomerates and raking it

the 1st diy repair i did was just last year changing the leaking top radiator hose i thankfully caught before heading out of town to KCMO after just having the dealer totally flush out the whole coolant system (instead of just the regular drain and fill that i had always previously had done with one of the routine package deals)
i took the truck back to the servicing dealer Corwin to show them the leak and they refused to fix it on their dime saying that was not touched by them which i thought it looked like it had. They wanted $280 to change the hose including parts and replace lost coolant. i called bunk and ordered some new coolant online a new hose from camelback and clamps (which the clamps were not needed) cleaned off the corrosion buildup which is probably why it was leaking idk and have had ~40k of leak-free miles since then! it took me awhile, a few hours, to get that task completed so i probably did not save that much but i did have a nice dinner while waiting for the engine to cool down so i could just yank that hose off and wash the spilt coolant on the driveway off into the grass

 

Not sure why today I’m adding this but today I’m adding it!!! I used the Timmy toolman videos and all worked well but he made second one to correct some issues... watch it too. One thing he did that could’ve been done better was installation of belt tensioner. He did it with electrical tape and swivel. I used that too but found that you could set all that up with ratchet, extension, swivel w/tape and socket w/ bolt inside per video. Found out though that you could have all this running through access hole from bottom. Then angle it all so that it’s all out where you can see it then put tensioner on bolt and with extra hand hold it together and put it into place. This was much easier by far and could’ve been done with eyes closed. Barely starting it like video stated or maybe not installing it till belt was already on. Hope you understand what I’m saying because it helped and worked better without getting debris all over ya while looking up.

Lastly while doing this and deciding what can be done while in here???? If you decide to do valve covers unhook wire harness. From a/c, alternator, sensors and etc. his videos show you having great difficulty on drivers side that can easily be avoided. It also won’t stress your wire harness and it’s connectors that way. It’s easy to remove for more slack but be careful undoing the connections so they don’t break. Never force anything it should come apart easily.
