Hello everyone, I thought I would share, I had my cambelt done today at the garage they decided not to replace the water pump as it appears to be okay. So they got it all done and took for a test drive and the water pump snapped where it connects to the fan. Ruined radiator fan and trans cooler.

Lesson learned today.. Always replace water pump lolpost-119800-0-03946500-1379052903_thumb.jpg

Wow! That's the first time I've seen that. I would be hesitant to go back there. It's really worth replacing the water pump, idler, Tensioner and cam seals when it is all apart, especially when you are paying someone else to do it.

The waterpump is driven by the fanbelt not the cambelt and before i took it in the fan belt was pretty tight, I think that maybe they didnt install it correctly after inspecting it and it got jammed i dont know how else it could break there.

They are going to replace the broken parts (hope they dont charge me for it) I will see how it turns out when i pick up on monday

Wow that would've sounded horrible when it went. Definately getting a pump change when the timing belt is replaced. :O

I recently did my ancillary belts and even though my fan belt was tight, I had to tighten it again to stop squealing.

Kinda makes you wonder just how tight is overtight.

I had a substantial piece of the water pump snap off underneath the shaft. I was freaked out too.

Timing belt was replaced months ago.

So yeah, I believe it. Looked like the casting had a hairline crack.

But you have to take off all the ancillary belts to do the timing belt ;)

Or possible the shop used a breaker bar and cranked the car to crack the nut but screwed up and cracked the water pump.

Slight chance?

Big chance! Even if the water pump was a cheap n nasty casting it didnt "blew to bits"!

Its had a lot of force put on it and its been broken

I would never do that - just put the car in gear and use some of the man power to torque it out - cranking the car is so bloody dangerous i reckon!

I always crack the nut by cranking it over. It only takes a split second to do it, just make sure the brake bar is suitable. My car is an auto so the put it in gear thing won't work.

Why are they cutting corners? Sounds like a shit shop who doesn't care. They also caused this. I changed my water pump when I did my belt not because it needed to but more the might as well factor.

Also I never needed to crank to crack the nut. Big breaker bar to take it off and properly torqued on. I'd also bet they used a rattle gun or just guestimated the torque when putting the nut on the crank.

      I have more than enough digging, laying blocks, moving gravel, airrating, feeding and top soiling the grass, and setting up the veggie gardens growing some seedlings,  and then removing all the unused rock to keep me busy for the next few months at least,  hopefully the rain stops soon so I can get a few hours in this arvo, but, before that Sunday is washing day, is every body happy, you bet your life we are Nice country road day drives are a day off whenever I'm muscle sore from all the landscaping at the moment, but, more epic multiple day drives will start once the majority of the big jobs outside are completed

      Recommendation for engine oil funnel spill free

      By MBS206 · Posted

      I thought I'd come back and add something I JUST learned. A Toyota LandCruiser with a 1HZ, mates perfectly with a bottle of Nulon brake fluid. As in, it perfectly screws in. Great make shift funnel when you cut the bottom of it off. This may work for your Corolla.   Unfortunately, tipping a 10L drum is much harder than a 4 to 6L bottle, and they no longer include the easy pour tap which was just perfection to use previously.

      Fuel Pump Control Module & Dropping Resistor

      By EndZee · Posted

      Guys since i bought r33 gts25t coupe 1994 automatic a/t(manual swap 350z gearbox)  all i got is problems, always problems. Lets start with that when i turn key into ignition(ON) fuel pump doesnt always works. Sometimes i have to turn key twice Off/on/off/on until it primes. Its new, dw300 - 340lph. My gearbox broke so i did gearbox swap, install different intake manifold, injectors and i take pipes. Car was sitting in garage for more than half a year. I did assembly all not that long ago and when i turn ignition cant hear prime. All of sudden it stopped working. Theres many videos on YouTube how to make relay mod on r33 straight from battery so i did and it doesnt work! 😰 30 - battery positive  87 - positive from fuel pump to relay 85, 86 - one of two wires from original fuel pump wires(light blue, grey) and it didn’t work. so I check on ignition and took original BLUE relays wires from trunk, next to fuses. (I believe it’s IGN+ and ECU pin 18. it didn’t work…  tried connecting (IGN+ from og relay) and (ECU 104 from 1of4 FPCM wires) to my new relay 85/86 and it didn’t work.  I unplug FPCM. Didn’t work. im thinking what’s wrong   fuel pump is working, if I leave IGN+ on 85 and 86 straight to ground it works but it’s just nonstop. Since it getting constant 12v after key in ON. light blue wire gives me 6-8v.  so how this should be connected? What causing ECU not giving — on pin? Or I did sth wrong and that’s why it doesn’t work? I need negative signal on ECU that control fuel pump. What this should be?
