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.

      Strange issue RB25DET wont start

      By jtha7 · Posted

      Ps i found the below forum and it seems to be the same scenario Im dealing with. Going to check my ECU coolant temp wire tomorrow    From NICOclub forum: s1 RB25det flooding at start up Thu Apr 11, 2013 7:23 am I am completely lost on this. Car ran perfectly fine when I parked it at the end of the year. I took the engine out and painted the engine bay, and put a fuel cell with an inline walbro 255 instead of the in tank unit I had last year. After reinstalling everything, the engine floods when the fuel pump primes. if i pull the fuel pump fuse it'll start, and as soon as I put the fuse back in it starts running ridiculously rich. I checked the tps voltage, and its fine. Cleaned the maf as it had some dust from sitting on a shelf all winter, fuel pressure is correct while running, but wont fire until there is less than 5psi in the lines. The fuel lines are run correctly. I have found a few threads with the same problem but no actual explanation of what fixed it, the threads just ended. Any help would be appreciated.

I found the problem though. There was a break in one of the ecu coolant temp sensor wires. Once it was repaired it fired right up with no problems. I would have never thought a non working coolant temp sensor would have caused such an issue.

      Strange issue RB25DET wont start

      Hi sorry late reply I didnt get a chance to take any pics (my mechanics on the other side of the city) but the plugs were fouled from being too rich. I noticed the MAF wasn't genuine, so I replaced it with a genuine green label unit. I also swapped in a different ignitor, but the issue remains. I've narrowed it down a bit now: - If I unplug and reconnect the fuel lines and install fresh spark plugs, the car starts right up and runs perfectly. Took it around the block with no issues - As soon as I shut it off and try to restart, it won't start again - Fuel pressure while cranking is steady around 40 psi, injectors have good spray, return line is clear, and the FPR vacuum is working. It just seems like it's getting flooded after the first start I unplugged coolant sensors to see if its related to ECU flooding but that didnt make a difference. Im thinking its related to this because this issue only started happening after fixing coolant leaks and replacing the bottom part of the stock manifolds coolant pipe. My mechanic took off the inlet to get to get to do these repairs. My mechanics actually just an old mate who's retired now so ill be taking it to a different mechanic who i know has exp with RBs to see if they find anything. If you have any ideas please send em lll give it a try. Ive tried other things like swapping the injectors, fuel rail, different fuel pressure regs, different ignitor, spark plugs, comp test and MAF but the same issue persists.
