Hi sports fans.
Re: J35ELCTS
I have a question, and haven't found other comments on this forum of much help.
Is the job of thermostat replacement as big a job on this 29 year old engine as it looks to a hillbilly with only one functional brain cell?
The schematics I've seen show the thermostat to be at the top of the engine block behind the water jacket cover/cylinder head, (at least two gaskets, and a thermostat seal), my Seloc manual isn't very specific on the procedure.
I have, (hopefully had ), a steam issue where steam pours out the cooling water outlet in the mid-section under the power head. I couldn't find any hot spots with my infra red thermometer, butt: the steam is/was a major corncern.
I changed the impeller and the metal water pump housing, (which may have cured the steam issue, too early to tell after only a ten minute full power test run), butt: if she still steams it looks like I'm gonna have to break a lot of bolts when I change that darn thermostat. BTW: the old impeller wasn't too bad, (there was some rubber stuck to the metal housing), so I changed them out.
The fresh water engine is in very good shape, with even compression, good idle, and very easy to start. That said, the head bolts near the bottom of the power head are rusty, and the paint on the upper bolts tells me she has never been appart.
Any insights into this nasty looking job if the new water pump doesn't solve the steam issue?
Why would OMC make a routine maintenance matter such a large job? grrrrrrrrrrrr
Thanks in advance for any replies and or insights you might have.
Respectfully, JR
