I have a w115 with a 200 w115 engine. I live in the Philippines where it gets kinda hot in the summer. I leave my radiator cap half-open when using my car at all times. I do this because I have had my hoses blow out or get pulled out from the neck/hose clamps when the system builds up pressure. water does not spill out, and the temp never exceeds 90 or 100. Question: Would this arrangement (half open radiator cap) affect the water circulation in any way? I'm worried that this may result in poor water circulation or possibly heat localization which may lead to cylinder head or block failure. Your thoughts are much appreciated.
