Rem Posted April 3, 2013 Share Posted April 3, 2013 Sorry if this has been done to death but I have searched through this and other forums. I'm looking for the best place to buy a new water pump for my 300tdi. What I'd picked up on is that some places were supplying brands which are less reliable then others. I would appreciate an up to date heads up on what brand and who to buy from please? The pulley looks to have sheared pretty well off on mine taking the belt out too. Might this suggest that something else might have cause the failure eg tensioner? I wanted to have a go at replacing it myself but can't decide from what I've read, whether it's going to be a nightmare or not LOL. Also, do I best get a viscous spanner to get the fan off as well? Thanks guys Quote Link to comment Share on other sites More sharing options...
cackshifter Posted April 3, 2013 Share Posted April 3, 2013 If you have to replace the pump (and you do) you are better getting a set of 3 new water pump pulley long bolts, and a 'P' gasket as well, and going the extra bit and replace the gasket, which lives behind the pump.There is an Uncle Les article in the tech archive http://forums.lr4x4.com/index.php?showtopic=7547, but it is very straightforward unless you have trouble extracting the old pump bolts, and tbh there is no way of knowing till you try. Odds are you'll damage the P gasket seal while replacing the pump. As the bolts screw into aluminium, generally it's better to crack the bolts if possible while things are warm - probably not an option for you. I smeared bolt threads lightly with copper grease to try to keep water out. A viscous spanner is always a good idea to have, it makes loosening it rather easier, though I'm pretty sure you can manage the water pump with the fan on.

Rem Posted April 3, 2013 Author Share Posted April 3, 2013 Thanks for that. Any heads up on brands to buy or avoid. Heard QH? Is to avoid? ****part too! Quote Link to comment Share on other sites More sharing options...
western Posted April 3, 2013 Share Posted April 3, 2013 avoid Britpart, QH, Bearmach, Allmakes are all OK. Quote Link to comment Share on other sites More sharing options...
Aragorn Posted April 3, 2013 Share Posted April 3, 2013 QH went bust last month, i'd be avoiding them... Quote Link to comment Share on other sites More sharing options...

Rem Posted April 3, 2013 Author Share Posted April 3, 2013 Ah OK, off hand, who stocks Allmakes then? Quote Link to comment Share on other sites More sharing options...

Rem Posted April 4, 2013 Author Share Posted April 4, 2013 Sorry, can I just ask, if the pulley has pretty much sheared off like on mine, would I need to be looking at possibly a new belt tensioner too? I don't know how old the pump was but it may be not so old looking at the casting. Quote Link to comment Share on other sites More sharing options...
cackshifter Posted April 4, 2013 Share Posted April 4, 2013 Unlikely the belt tensioner is damaged I'd have thought - unless it's bent. If the tensioner pulley is still in line it should be OK. Bearings in the tensioner pulley can be replaced relatively easily and very cheaply (again see Tech Archive). Quote Link to comment Share on other sites More sharing options...
Tanuki Posted April 4, 2013 Share Posted April 4, 2013 While you've got the front of the engine in bits, it makes sense to replace any tensioners irrespective of how they may feel. They're cheap, your time isn't. Same goes for all the belts - reassemble with new ones and you know the job's good for the next 50,000 miles.

Rem Posted April 5, 2013 Author Share Posted April 5, 2013 OK, will do then. I'll look up changing the bearings in the tensioner as a new one was quoted at £44 for decent one and £24 for a, um, dunno what type really :-/ Quote Link to comment Share on other sites More sharing options...
TheRecklessEngineer Posted April 5, 2013 Share Posted April 5, 2013 You should get the bearing for the tensioner for under £10 - more likely under £5. It looks like you've been quoted for a whole assembly. Quote Link to comment Share on other sites More sharing options...
RILEY Posted April 5, 2013 Share Posted April 5, 2013 Hi mate the advice is, on certain jobs (they all range in difficulty)if its easy and cheap chance your arm(unless safety critical)if you really dont want to do it twice (and who would really) buy genuine good luck Quote Link to comment Share on other sites More sharing options...
RobTheGob Posted April 5, 2013 Share Posted April 5, 2013 Wow - I'm glad I found this thread. I was planning on buying a QH water pump, since I read in another thread that QH was the OEM part. It seemed to make sense to me - since it was priced right at the top end of aftermarket (double the price of the "cheap" stuff). I was searching to find out how the Bearmach supplied QH differed from the Britpart QH, since LRDirect has a 3 UKP difference between them. With QH in receivership - warranty is meaningless. I doubt I'll be able to use a warranty (since I'm 8,000 KM from the UK) - but I'd like the option, just in case. Based on what I read above - I'll be choosing the Allmakes parts...

sgnas Posted April 6, 2013 Share Posted April 6, 2013 http://www.paddockspares.com/peb500090g-water-pump-and-gasket-oe-supplier-300tdi.html Airtex is the oem. The one I got from the main dealers was airtex. Fitted after two after markets failed in less than 3000 miles! Surprisingly the dealer was not that much more expensive. Annoying thing is I only changed out the original as it had a small amount of play and I was replacing the p gasket so it had to come off anyway.

cackshifter Posted April 6, 2013 Share Posted April 6, 2013 Yes, though an Airtex one I fitted lasted less than 2 years (8000 miles) , I had a bought a spare (QH) and that is on now, after the bearing broke up in the Airtex and threw the belt off and coolant everywhere. I'd say, for what it costs, not a bad idea to have one on the shelf, as they break at the damndest of moments. Quote Link to comment Share on other sites More sharing options...
RobTheGob Posted April 7, 2013 Share Posted April 7, 2013 My Defender is a NAS 90 - with a 3.9 V8. Paddocks indicate the QH is OEM: http://www.paddockspares.com/stc483g-water-pump-and-gasket-v8-quinton-hazell.html My current water pump has a ton of free play - and leaks now and then. I was thinking about buying the Allmakes - perhaps I'll buy two, just to keep one as a spare... Quote Link to comment Share on other sites More sharing options...
