Hello, new to the forum as just bought my first Daily. She's a mk2 1993 49-10 2.5 td ex NHS van, with a mere 51,000 KM on the clock. (not sure why the taco and speedo are in KM, anybody shed any light?) she's a bit tatty but immaculate underneath, around the windscreen and where it counts and she's got a full MOT. drove her back from the south east to Cornwall with no issues, apart from a real lack of power on the hills. The cruising speed on flat was 60-65, which is perfect just as i expected. However when i hit a hill, the speed would drop, sometimes down to 40 or below even if i shifted into 4th gear. a drop in speed is to be expected but considering it was carrying no load i was expecting it to feel a little more torquey. It got me thinking...... i couldn't hear the noise of the turbo (I've had several turbo charged cars before and can always hear the turbo spooling up). Obviously its a pretty old and loud diesel engine, so should i be able to hear the turbo over this? or is it a very low pressure turbo that doesn't make a lot of noise anyway? could it be not working and thats the reason for the lack of power on hills?
Whats the easiest way for me to check? Besides this the van ran very well, I'm just a little concerned as its going to be a fair bit heavier when its got a load and i don't want to be dropping to 20mph on hills!

The only thing that doesn't work on the dash is the coolant temp. What is the best way to address this, is there a sender/sensor that i can check/clean ?

Also I'm pretty sure the fan belt is squeaking, how do i tighten this?

Thanks in advance, this forum looks great and very helpful!
No doubt it will be assisting me with my new van :)

:D

It is a bit slow on the hills with a big gap between the gears it seems. Some people have added intercoolers. I just put up with it. Like any vehicle entering a hill at high revs gives the power to keep going.

Fan belt squeal, there is quite a bit of general advice on the web. Surprisingly I think a squirt of WD40 works - I don't quite get that.

Engine temperature. Check the wiring, far more likely than the sensor itself, though even that is easy and cheap to replace.

Welcome,
Speed sounds normal, they are heavy. Taco/speedos are in Kms (miles will be there too only smaller). As Mark suggests look on the net for how to tighten a fan belt. it is very basic. If you are new to mechanics maybe do a basic course at a local college. Get a book out of your local library or search the net for basic how things work. The MK2 is a very basic vehicle so most basic stuff will apply. There are a few bad Iveco designs but overall a good vehicle. One of the main problems is rust. Try to keep that at bay. Change the oil and filters regularly (oil, air, fuel) and change the cambelt if you don't know the history or it has not been done for 5 years maximum. Check the condition of your fan belt and if in doubt change it, they are cheap.

the original brake pipes were steel, so they could rust. Worth checking the condition visually, and perhaps use a magnet to see if they are copper or steel, then pay extra attention to the condition if they are steel.

Not sure on the older vans but the belt squealing I found came from the alternator belt.
Check the alignment of pulleys, my alternator pulley was out of alignment with the water pump pulley.
I fitted a separate water temp gauge. The temperature can climb and fall quite a bit on these engines.

Climbing hills is something of a work up with weight/power of these vans. Not alot you can do, if you sort it out let us know :D
