92 Sierra is loossing coolant. So I topped it up yesterday, ran it down the driveway and left it running. Watched the engine bay intently for 30 minutes without finding any leakage. Walked away to get a coffee, and when I returned there was a high pressure drizzle of the green stuff coming from somewhere under the rear right underside of the carb area. Stopped engine and har a good hard look. Cannot identify location of leak. Sarted it up again, 30 minutes later no leak. Talked to her indoors for 5 minutes, and there is a new puddle on the intake manifold, watched as the leak suddenly stops. Still cannot find leak. Ran engine today for 1 hour, no leak.....sad. Going to replace all the hose wear today. Any ideas?

Sounds like the coolant pipes used to heat the manifold / carburettor. http://www.suzuki-forums.com/attachment ... 162828.jpg
