Leaky thermostat - which one to replace?

[akiller]

Not the best of advice but easiest thing to narrow it down is give them a ring with your reg? I like to take both items and just bring the wrong one back for a refund, ask them if that's an option?

No idea how you go about fitting it as Im not mechanically minded :p

That was after I put the reg into their website so I'm assuming the desk staff will have the same info. Getting similar mixed results from other places too. Figured people on here would be more trustworthy .

My only experience with ECP thermostats is that they don't supply you with the correct seal. Its just an O ring. Seen it on two occasions.

I ended up going over to peugeot and just buying the seal for pennies.

I just tested (what I believe) the original 'stat in a pan of boiling water and it opened fine so just reused with a new seal.

Ah I figured as much. Presumably the seal I linked would be a better.. seal than the O ring and less likely to leak?

My temperature seems a little erratic at the moment, I've seen it go up to ~91 then jump back down to ~85 for the next few miles so I think it might be on its way out. For the sake of £5 I may as well replace it.

Another stupid question but when you say go into Peugeot, a dealer you mean?
