Replace your water pump.

Is there any leaks you notice if not check the exhaust pipe for traces of oil. Is the exhaust smoking if so then a compression test needs to be done to verify if the piston oil rings and scrapers are in good order

If there is oil in water, then there may be a head gasket leak. However, half a quart of oil loss every 15,000 mi. is not bad. If van runs perfectly, then I wouldn't worry too much about it. Maybe try some Bar's Leaks Head Gasket Repair for $30 or so to fix the slow leak in the coolant system.

It's not the transmission, because you wouldn't see the space that the transmission fluid fills, and it's doubtful that it's the brake fluid, the brakes will act up all the time (stop lights, etc) if that were the case, so it must be the powersteering fluid. If your car is sort of a pain to steer around corners, the slower you go, the harder it is to move the wheel to turn, and you hear a sort of whiney noise when you get into a deep turn, or are turning slowly, that would for sure be powersteering.

Most cam belts need to be changed every 60,000 miles. I would change again somewhere around 126,000.

check to see if you have power at the hazard light switch, it could just be unplugged, if u can get another good switch swap them over, i know its a power prob to that haz switch.

Get this manual online at www.reliable-store.com and get complete guide on whether to repair or not, service it, and how to repair etc, along with wiring diagrams, electrical diagrams, torque specs, error codes, everything.

which is standard or the best motor oil for HDI?

Hi, I have a 2.0HDI Expert which was doing the exact same thing as yours, blowing thick black smoke, sluggish and loss of power on gradients, a hissing sound and surging. I replaced the air flow meter but that didn't help. I was told to replace the turbo but a turbo expoert told me not to as it would blow white smoke if it was faulty. I was then told to replace the injectors but a diagnostic test showed them to be functioning fine. I was then told to look at the intercooler which had thick sludge at the lower left pipe. I replaced it today - Sunday 12th July and it is now driving like a new van. It now pulls me up gradients with ease in 4th and 5th instead of having to drop gear to get to the top. I got a replacement from Euro Car Parts for £147 inc VAT. To tell if this is your problem, look through the gaps in the lower section of the bumper at what looks like the radiator and look for sludge over the inside of the bumper and all over the pipe where it joins the back of the radiator (intercooler). Also open the bonnet and look down behind the grille for the same sludge. Hope this sorts it for you. Barry, Newtownards, Northern Ireland.
