My son's 99 Miata had a small water leak at the back of the head. After doing some investigation I found the source of the leak. There is a housing on the back of the head which l removed. I assume this is the temp sensor housing. I removed it and looked at the gasket. It appeared to be ok so I was confused as to why it was leaking. A closer look confirmed that the housing is cracked.
Do these housings crack often?
Is this referred to as the temp sensor housing? I need to know what to ask for when I call the dealer tomorrow. If anyone knows the part number, that would be greatly appreciated.
Thanks,
Erik
