Coolant pressure issue
I have a 1998 CV that I have a cooling system problem with. While merging I punched the throttle and immediately started losing coolant. The coolant temp sensor and the housing it’s threaded to blew out of the manifold. The engine hadn’t been running long and the thermostat wasn’t open yet.
This seems odd to me. Has anyone else had this happen to them?
Any ideas as to what might have caused this? I’m leaning towards faulty rad cap and maybe a pluged up hose or blown head gasket.
Also, I found an orange rubber plug loose under the manifold. It looks like it fits over the end of the temp sensor. Is that where it came from?
And one more question, is that sensor housing, with a taper and an o-ring, going to hold if I just press it into the manifold again?
Appreciate any help,
