1984 E 140 t-stats question

[ted655]

I finaly got the right manual for my E 140. Upon browsing thru it, I read about T-stat service. All it says is while the powerhead is removed, service the T-stats. Then how. Can that be right? I ran right to the motor and looked, they sure look inaccesable to me. Tucked way down on the back side.<br />So on this year V4, the least little anything with the T-stats and you dismantle everything and pull the power unit? Say it ain't so.<br />Anyone know where THAT engineer lives? I...er, want to give him a little something, uh huh.

I'll brighten your day - - - It ain't so. I did my 1987 OMC V4s (bubbleback style) 6 months ago without removing the powerhead - - and I am a driveway wrench. I used a 1/4" socket with a extra long extension and universal plus a 7/16" open box wrench. It is a pain but can be done. You may have to drop the pan at the base of the motor to get to the botton bolts of the cover.<br /><br />Make sure that you review the diagram on reassembly.

The thermostats can be changed without removing the powerhead, however it does take a good amount of patience, the proper tools (offset boxwrench, universal sockets etc)..... and a book of your favorite words.

I have seen it done by drilling 3/4" holes in the back of the pan to access the thermostat housing bolts. Once the Tsats have been changes the holes were plugged with plastic/rubber plugs like used on car doors.

It was a good thing you said "drill", Walker. In my caveman brain I was going to use my saws-all, then pop rivit a plate back on.<br />An offset wrench and a wobble socket I have. I don't cuss outloud. I tend to stick my tongue partway out and mutter under my breath. Anyway, Thanks everybody.

Re: 1984 E 140 t-stats question

You can do it, like Joe Reeves said.<br /><br />It's best if you remove all the bolts holding the lower belly pan and mid section surround.<br /><br />Once that is done, you can force the rear of the belly pan down enough to get easier access. Been there, done that.
