1.1 Engine Code

[Mike199025]

Hello, my dads 2006 c3 1.1 has apparently broke its timing belt. He is talking about swapping engines if I confirm the belt has broke and damage as been caused(more than likely) I’m wondering where is the engine code located? Edited July 19, 2018 by Mike199025

The engine code is part of the VIN. You can find this at the bottom left side of the windscreen, on the Warranty and Maintenance book and on the V5C registration document. From the Haynes manual, the 1.1 litre petrol engine is type TU1JP and code HFX. The HFX should be seen within the VIN. If you go for a used engine, make sure it is from a C3 (preferably the same year) since ones for other engines such as the Saxo can have different manifolds. You should also replace the timing belt/pulleys/tensioner/water pump on any used engine since you will not know when it was done. The petrol engines are prone to oil leaks from the timing belt end of the cylinder head so check this so you are not faced with changing the head gasket.

Thank you! I will be changing the clutch also before putting new engine in

 

Thanks for the advice

This topic is worth a read if you are thinking of repairing your existing engine. http://www.citroen-owners-club.co.uk/citroen/topic/23157-timing-marks/

Okay after checking it out the belt as stripped a couple of teeth, would putting a new belt on be worth it? Or should I get put a replacement head on it?

Based on the topic linked in post 4, the valves might be bent. You could remove the spark plugs and look at the top of each piston and see if any damage can be seen. Anything else is going to need a bit of dismantling to see how bad it is. Without checking for damage, you could try a new belt and turn the engine over by hand to see if there is any compression which might indicate if the valves are still ok.

 

How many miles/years is it since the timing belt was last replaced, or is this going to be the first time ? The replacement interval is usually 10 years or a mileage, whichever comes first but this is provided Citroen parts are used. Oil leaks on to the belt will reduce the life of it.
