Hey there,
I recently did a whole bunch of cooling maintenance on my '94 JDM 80, to include the PHH, water pump, heater hose lines, etc. Included in that was a new thermostat. The initial reason for me opening all of this up was because I had a small leak from a heater hose on the T-fitting. That has been addressed.
Since replacing the thermostat, I seem to have a worse leak than the heater hose I had before. When idling, it's fine, but under throttle there is a fair bit of coolant surging from the top of the thermostat, specifically where housing bolts to the block. I torqued it to spec and took forever to get the thermostat and new o-ring in place. This may sound dumb, but I'm hoping it'll seal itself with a few heat cycles. If not I'll have to pull it back apart.
Does anyone have any experience with this issue? Maybe use some RTV on the thermostat housing? Thanks in advance.
