    At a not inconsiderable cost, I had the stat replaced on my old van as the engine temperature was constantly swinging up and down (never overheating) and rarely making it over 75 even when fully warmed and driving loaded.

    I thought things seemed a bit better after the new stat but it still didn't behave as I expected it ought to.

    Anyhow, I was going to do an oil change today after the engine had been started from cold and idled for a couple of minutes I realised that the radiator top hose was getting warm. Surely this can't be right?

    Time to go back to the garage? Just what is normal for these engines?

    PS. My sump plug has a hex socket and I've misplaced my micrometer. Does any know what size hex it is?

    Normally the heater hoses get warm first then the top hose will get warm.
    If I remember correctly the sump plug is around 22mm

    Cheers. I'm coming to the conclusion that my new stat is definitely faulty. Back to the garage with it!

    I had a problem with the temp guage. It may be the ECU or Cluster,,,

    ECU? Dunno if they had been invented back in '97. :Laughing:

    Irrespective of what the gauge is saying, the top hose shouldn't be heating at the same speed as the heater hoses so something isn't right. I have left it idling long enough to get it up to an indicated 90C when the cooling fan kicks in.
