Thermostat O-rings
Well, if ever this weather lets up, I'm going to have to change the O-rings as I have coolant in the "V". Although I fitted a new thermostat a couple of years ago, I can't remember whether I can change the O-rings without removing the thermostat, as I do remember it was a tricky job!
Can anyone advise me please? Thanks, Malc |

Hi Malc,
Yes, you'll need to remove the thermostat, straight and curved plastic pipes to replace the four o-rings (CDU3858). Whilst it's a bit more work, I'd recommend removing the plastic intake and front (left) inlet manifold. With them removed you have much better access to clean the mating faces in the engine block (with some Scotchbrite or similar) that the o-rings sit in and you can be confident that it's all properly seated. You will need a new manifold gasket (LKJ100992) though. Hope this helps.

Thanks very much Matt. I can see from your excellent photograph that the access is vastly improved! Thanks for the part No. refs as well.

And Malcolm, after reassembly make sure that you push the serrated clips on the straight pipe fully outwards to be in close contact with the water pump boss and thermostat housing, then squeeze them tight.
I'd recommend ordering two new clips (along with the O rings) to make the job easier. The part no. is PYC 101320. Simon

And, if you have one or both parts of the intake manifold off don't forget to order new manifold gaskets.

Cooant in the " V "
Hi Malc,
Interested in how the job panned out regards replacing the "O" rings on the straight pipe and fitting the serrated clips flush up to the water pump at the one end and the thermostat housing at the other end thinking that surely would eliminate any seepage of coolant into the V. Very interested to know how it all went and that you cured the problem. Cheers Rick' |

Thanks everyone for your help and advice. I'll be sure to let you know how I get on as soon as we have a couple of dry days - when ever that might be!
Cheers, Malc |
