Name that part

[driftin jo]

dam it, surely I wont have to take the head off though?

No...you won't have to take the head off but you will have to take the engine out.

[driftin jo]

Seriously though you will be able to put a new plug in if you use a little ingenuity .

[HORCH]

hahaha thank god for that, I was worried for a second there, I'll find a way,

[HORCH]

can someone tell me where these go please? I'm putting my exhaust manifold on I've got the one thats definately the exhaust gasket but these have confused me?

[Tonks4x4]

Spare set for different type of manifold I believe they are for the 7A 20v engine

[mcandmar]

Yup, early 5-1 tubular manifold uses those separate gaskets.

[HORCH]

I did wonder, but I thought I'd ask, you seem to learn alot by putting a cyinder head on

[HORCH]

I'm looking at my radiator fan now because it comes on soon as you connect the battery up, I've read its a faulty earth somewhere, whats this though? it comes from the loom that joins to the fan, does anybody know where the earth for the fan goes to? cheers

[Error404]

fan resistor I think, its a 3B specific part AFAIK

[willg54]

are the earths down on the front left, underneath the washer bottle region?

[newsh]

Thats the fan resistor, it mounts to a hole on the fan support. (I can take a pic of mine if you want) Fan just has the 3 pin plug, not sure where the earth goes to the chassis..

[willg54]

on this plate here i think

[Error404]

nope thats the ABY fan resistor pack, different to 3B
It doesn't really matter where the earth goes, there is a point nearby on the ABS pump bracket, or you can drill a hole and make your own one whereever

[HORCH]

ahh right, yeah I took it off the fan shield, well the car is a 3B so if thats off an aby would it make it stay on? does the fan work by earthing or the earth being broken? by the thermo switch?

[UrS4boy]

Ok, if you have torqued that nice clean head gasket down your not going to like this. The large hole should have a core plug in it sealing off the coolant jacket. The small threaded hole is the engine temp sensor, has a white 2 pin plug on it.

Here is a photo with the G62 engine coolant temp sensor that the ECU uses.
