    The engine temperature in my 550 went through the roof this afternoon and when I stopped to investigate, steam was coming from the top of the engine. Any suggestions?

    I'd be suspicious of the long bypass hose that runs front to back directly underneath the intake. That baby lives a hard life and they're known to let go. Easiest way to diagnose this is to get a cooling system pressure tester, pump the system up to 14psi or so and see if you find the source of the leak. Could also be one of several other hoses but the one under the intake is the usual prime suspect. Good luck, let us know how you get on.

    See #45 in the diagram to see which one I'm referring to..

    That certainly seems to fit the symptoms, thankyou. I shan't be able to deal with it immediately, but will report back in due course. Thanks for your help, Aaron.

    Both Mark and Harvey at Carrs concur with your diagnosis: they are picking my car up tomorrow. Assuming that proves to be the problem, I am intending to replace all of the hoses while I am about it.

    Make sure you use 575M silicone hoses for the three that have been upgraded. Or get a full set from SRI.
