Customer Question

I have an LDV convoy minibus banana engine
It has lost approx 3 litres of coolant in a week pipe into radiator is very hot one coming out not so is it the thermostat ,water pump or something else
Also battery light remains on initially upon starting need to give a little revs and it goes out battery replaced last week
Sounds like fan belt slipping when first started can stay on a good 2-3 miles if I depress clutch and hold for a few seconds costing when engine is warm it tens to stop the noise is this an alternator issue someone has adjusted the fan belt for me but it doesn't seem to have changed anything hope you can help

How long does it take to start the engine when cold .

What colour smoke comes out the exhaust pipe when it does finally start up.

If you have tensioned the belt and still making a noise replace them .

This is why the battery light is staying ON for a few miles in the time of the belt noise .

If the top radiator hose is hot and the lower cold then remove and test the thermostat.

If its the first thermostat from new replace but still need to test . if its good check radiator for blockage.

Do a radiator flush if needed.

belts have been replaced, a rev of the engine will take the battery light off, normally starts first time but is occasinally a little sluggish when cold will try thermostat and let you know

When you start the engine and you have the noise from the belts spray water onto the belts and let me know if the noise goes .

i sprayed WD40 on them last week and it didnt appear to have any real effect
if i leave the van ticking over in the morning for about 10-15 minutes it is rare that i get the problem i have been advised that it may be alternator but a test on it has been inconclusive hence the battery change as it was not wanting to start

No if belts are good and battery is new then the alternator has a problem .

You need to check the alternator output voltage on start up and when making the noise

you may have a bad alternator which are known to give out a noise when cold and quite down when warm .

bad bearing in the alternator, and a bad voltage regulator .
