Water Pump Problem

Forum: 

I'm hoping I can get some help here, as I'm at a bit of a loss to know what to do. I bought a used Land Rover 90 with a Daihatsu diesel engine fitted. This all seemed fine, but I've had the vehicle overhauled (which has taken more than a year! Grrr...), and now that it's just about ready, the water pump has seized up.

The garage reckon that the engine I have is a DL50/55 (which, if I'm not mistaken is a 2.8L engine - I bought it believing it was a 2.5L engine - maybe it's a DG?).

So, I desperately need a new water pump, but don't have much information to go on. Apparently it's a 3-outlet pump (2 one side, 1 opposite), with 4-bolt fixing. I don't know how specific the water-pumps are, whether there are different versions for each engine revision, or what).

I'd really appreciate some advice from anyone that knows anything about these things (and I'm sorry if I have offended anyone's sensibilities by posting a question about a Land Rover! - I have noticed other transplanted Land Rover questions on this site!), or even better if anyone knows what it is I need, and knows where I can get one.

Many thanks in advance for any help,

Dave

Dave, First, your correct in

Dave,
First, your correct in engine designations. The earlier 2.5 was the DG. The later 2.8 is the DL. Now, there are a number of variants of the 2.8. There is the DL51, 52, 61, and 62 at least. They are the same basic engine, but modified in the later versions first for the turbo, then the intercooler. As far as I know, all the waterpumps are interchangable, however there are some differences. First is the cooling fan. There are different mounts for the viscous fans, and the ordinary ones. Also, the later ones dealt with more cooling requirements. The outlets to the left of the fan hub are, top radiator hose, and heater hose, and the right are bypass hose to thermostat housing, with a blanking plug in front of that which is used to take coolant to the oil cooler on later models.
I think the overriding factor for you is what type of fan you have, and get the appropriate pump based of that fact.

And no, we wont hold the fact that you have a landy against you. After all, it was your mistake, and you have suffered enough misfortune. LOL

Water Pump Problem

David, many thanks for your reply.

I'm afraid I'm rather ignorant about most of this stuff, as I'm a newbie to the whole 4x4 game. As far as I know, it was a viscous fan, but this has been removed and replaced with a Kenlowe thermostatically controlled electric fan. Does this mean I don't have to worry about fan mountings?

As for the engine, it is normally aspirated, and it does have a great big orange sticker saying 'DL' on it, which might be a clue. Presumably the guys at the garage would be able to tell the difference between a 2.5 and 2.8 litre engine?

I'm hoping all this means that there's a nice simple answer to which pump I need, but I seem to have been a bit cursed with this particular vehicle, so I'm not expecting it! Smile

I have a picture of the offending item if it would be of any help.

You will still have to get th

You will still have to get the correct pump, as the fan pulley uses the same mounting bolts, and these differ from pump to pump. Chances are, if its a naturally asparaited motor, its a DL51. Check the cover behind the bottom pulley. If its made of alloy, it reinforces my guess. If its plastic, its probably a different designation. Dont quote me though. I believe Millers (or Millens)is a large supplier of Daihatsu parts in the UK. I dont know if they have a web based ordering system, but if they have, a download of the pic to them may be of assistance.

Thanks!

Thanks again for your help. There's a place called Milner Off Road I found on the web. They list two different types of water pump, but without details.

http://www.milneroffroad.com/MECH2.HTM

I have written them an email, and hope they can shed light on my problem.

I'm still a little bit concerned that maybe the garage has got it wrong, and it IS a 2.5L engine from a F50/55, rather than being a DL50/55 engine ...

Anyway, thanks for all your help.

Engine/Water pump

Dave,

There should be an engine serial number stamped on the exhaust manifold side of the engine near the front (well that is where is was on my two fourtraks)

Do you have a picture of your old pump? I have one that I removed from on of my Fourtraks a year or so back. (mine was a 1990 2.8TD)

Cheers

Dave
You said the rocker cover has a sticker on it that says "DL". Dead giveaway, unless the cover has been previously changed. The older 2.5's were "DG"s.

DL/DG

Hi David,

The sticker does indeed say "DL" on it, though I can't remember what else - nothing else pertinent I can remember. I'll take some more photos tomorrow. I'm not convinced that anything about the vehicle is straightforward, so it wouldn't surprise me if the cover had changed ... It seems odd the vehicle would have been sold to me as a 2.5L engine if it was 2.8L ....

There was some trouble identifying which glow-plugs I needed - in the end, they (the guys at the garage) sent off one of the existing ones, and got some matching ones back. Unless I'm mistaken, this should have given a good idea of which engine it is. I'll double-check with them tomorrow.

Cheers,

Dave

Dave Im 99.9% certain you ha

Dave
Im 99.9% certain you have a gear drive DL 2.8 running the later viscious fan waterpump. Looking at your pics, the timing belt casing looks the same as my alloy casing. It has the Daihatsu "D" to the right of the crank and waterpump pulleys. This part also has a bulge in it. Looking at the pic in a DG parts manual I have, this area of the timing case is flat, with no "D" stamped on it, and none of the radial reinforcing bars around the edge of the two round bulges. One question, to the left of the thermostat housing, where a black wire dissapears to in your pic. Is there a sender in that side of the housing, as well as one almost immediately below that sender in the head? The one in the housing should have a rectangular green plastic plug, with two terminals, and the one in the head just one terminal. If these are there, then this leads me even more to think its a DL.

On another point, is the alternator the Daihatsu one. If so, it should have a wider pulley, similar to the waterpump, and crankshaft. In that case,you should be running the wider 15mm fan belt, not the narrower one you have fitted. I am led to believe running the narrower belt in the wide pulley causes premature wear and failure of the belt.

Cheers
David

I'll check

I'm going along to the garage shortly, so I'll try and check out these and some other issues. I'll certainly check the alternator while I'm at it. If I get a chance to remove the water pump, I'll take some more pics.

Thanks so much for your help, David.

Pictures

Hi H,
I only have pictures of the pump in situ, which I don't think are terribly useful. Here's links to them (700k+ pictures):

I'm going to try and get the pump removed tomorrow, and see whether it's possible to strip it down and see what's wrong with it (don't know if this is going to be possible). But I'll also be able to take some better pictures.

I'll look out for the engine number too - though the guys at the garage didn't seem to find it, despite removing the engine ...

Cheers,

Dave

water pump,

If nothing else, she's nice clean engine. let me know when you get the water pump out. Where in the world are you??

I'm in SW London, UK.

I also got a reply from Milner's today, as follows:

If the engine is gear driven timing (tin ally timing cover) - water pump 001475 - £45.00
If the engine has a timing belt (plastic timing cover) - water pump -001476 - £45.00 + v.a.t.

Now, I have no idea about the timing cover. I didn't get the reply until after I'd visited the garage.

David mentioned here that he thinks it's likely I have the gear-drive timing. If this is so, then I may have found my solution!

Any thoughts?

Cheers,

Dave

Do Milners have a return poli

Do Milners have a return policy if the incorrect part is ordered? If so, then go for the earlier alloy pump, and if necessary, swap it for the later one. Im more convinced seeing the steel plate held in place by the countersunk phillips head screws on the rear of the pump. Exactly like mine.
Here are some pics of a spare pump I have. It is an alloy timing cover DL motor. It suits the viscious hub fan. The centre to centre distance of opposite fan mounting holes on the pictured pump is approx 62mm. The same distance on my pump, non viscious hub fan is 51mm. Also there is a pic of an alloy timing cover.

Aha!

Thanks for those pics. Our pumps appear to be as similar as two similar objects in a pod!
I've compared the pics at every angle, and can't see any differences. I'll get on to Milners and have a word about returns policy etc.

It's definitely gear-driven timing, according to the garage. I was pretty sure that the timing cover wasn't plastic ...

Update: I've just ordered the part. They had 1 in stock. Should be with me tomorrow, so ... fingers crossed!

I'll let you guys know whether I succeed or fail.

Thanks!

My pump is not like yours, I have a timing belt one.

Success?

Thanks to everyone for their help. I have received the pump, and it's the right one!

I now also know I have a bigger engine than I initially thought - bonus!

So, all I have to do now is wait for the garage to fit the thing, and a couple of other little things, and I'll be back on the road. They said Friday, but ... they didn't call me. Sad

This forum has been a big help, and it's really nice that there is a supportive community, so thank you again.

Cheers,

Dave
