So, my brother's '89 GT w/156k on it decided to start leaking at the thermostat housing last week. We got a new elbow, gasket, thermostat, and new upper and lower radiator hoses from 50resto. Got it changed out yesterday, and well.....it's still leaking. We got all of the old gasket scraped off, sanded the elbow where it meets the gasket (it's chrome,was told to sand by a few other people I know that have bought the chrome ones). We got it tightened down fine. So, what to do next? Is there a sealant we can use to take care of it? Motor is due for replacement this summer, just need to keep it going until then.
