1.4 16V HDI 2002 A few new owner service questions.

Hello!

I recently picked up a C3 2002 1.4 16V SX.

I have a few questions regarding Power Delivery, Coolant, Oil, And general service with this engine. It's mostly new owner questions, I do not believe the car to have a major fault at this moment.

I'll start with Power Delivery.

Upon arrival the car had low power without the turbo active. The turbo wasn't spooling then hitting hard at about 3K rmp. I looked on these boards and found the relevant topics. Picked up one of the Vacuum solenoids and fitted it (with much swearing). The car is now much better at lower RPM. I can cruise in 4th at 30mph, and it doesn't feel to have massive turbo lag.

The car still picks up pretty quickly over 3K rpm. Is this normal or should the turbo have a smooth power transition across the rev range. I'm thinking about stripping and cleaning the EGR and feed tube, Just to be on the safe side. There are however very few video's showing the acceleration and describing how this car should feel when accelerating.

A new airfilter went in when I stripped it to put the new solenoid on.

There is also a solid but silent thump as the engine rocks on it's mounts when coming back hard on the power. Should I inspect the mounts or would this be classed as normal.

Coolant, I've picked up some OAT Concentrate, and plan on doing a full flush, Are there any pipes that are know to be problematic for airlocks. And is a reverse flush of the radiator advisable. Currently the water is dirty, looks to have no additive, the temps however are good. The highest I have seen so far is 3 bars sat in traffic for 20mins. So I assume that is working as intended.

Oil, It needs changing It looks to be a 10W/40 and is black. I've picked up some 5W/40 with a mid to low saps by accident. It's not in the car and I plan to take it back for a different product. I have a local Eurocarpart and GSF. A new filter has also been picked up.

That is what I got by mistake (It was actually the sales staff recommendation!) I'm just glad a read a little before dropping it in!

Would this product be better?

Many thanks! this is my first car in 10 years, I've spent too long without one!

Hello Iceni

Probably worn engine mounts, the lower gearbox one shows up first, but all 3 can get worn.

Look for the lower engine/gear box mount here on amazon, also called the dog-bone

You can also look through the list to find the other 2 engine mounts here, amazon but takes a bit of looking.

Won't do any harm and it could well be clogged.

There is a topic showing how to refill the C3 cooling system correctly, here that avoids the air-lock problems.

Oil specified for your engine is Total Quartz Energy 9000 5W-40 (click here). low SAPS is not specified for your engine.


Did you mention the fuel filter? Maybe it should be said again, anyway. Fit a new fuel filer available from here - euro car parts

Thank you for the responses!

I'll take that oil back and exchange it for a fuel filter. Then order the correct oil online.

I'll have a good inspect of those mountings. It could well be that they have started to go. For the sake of £20 it's not worth bothering a scrappy for them. There are a few internals and lighting parts (rear covers for headlight on both sides are missing!) I do need to bother a scrappy over so when I pop down I'll make a point of inspecting the mounts on whatever vehicles they have on the block.

The turbo actuator has no play in it at all. I need to have a really good look at it and see if it's working smoothly, I don't think there is anything wrong with it as the difference from the old solenoid to the new one is noticeable.

The engine itself is very clean, There is some oil on the rocker cover area. It's not moving down the block so I suspect it's a slow leak of the rocker cover. I'll keep an eye on it and if it looks to be worsening replace the gasket. There is also a touch of oil drawn into the air ducting past the MAF sensor, I would imagine that to be common on this engine looking at the layout of those pipes.

I'll crack on friday and do the water and fuel filter, And If the oil has arrived I'll get that done as well.

I didn't mention belts, They were all done at 65K, With tensioners and a new water pump, Alongside a full service. I have the receipts for both work and parts, As well as a date for that work.

The car itself has full Citroen service up to 65K. Then after that I have a log of receipts for services at local garages. And almost a full book of MOT certificates! I was quite surprised when they pulled out the paperwork.

Edit - correct oil ordered. Got it on Ebay for £23.99. Should have it for Thursday

Right.

Fuel filter done,
Water change done,
Pollen filter done,
Airfilter done,
Oil filter and oil change done.

Cars running well, Took it out for a short journey down the motorway, no problems, no overheating. And it was much quieter.

While I was on the ramps I looked at that lower mounting. It has indeed failed at these 2 points. I'll have a new one ordered and installed by next week. The others look to be fine.
