My Seloc repair manual for my 1997 Volvo Penta 4.3L with and SX outdrive
says the engine takes a 160F thermostat. That is what I installed in
spring.

The mechanic who worked on my boat after the overheating incident says it
takes a 140F thermostat and that is what he installed.

Does anyone know the correct thermostat temperature rating for this
engine?

Will running the wrong thermostat temp have a negative effect on the
engine's performance?

TIA!

Thanks for all the replies. Looks like I will be telling the marina to
install a 160F thermostat...........on them. ;-)


PS - I hope you did follow the most important advice provided in
rec.boats and verify the info with the Volvo service manual. While I am
very confident you will find the 160 temp is correct, you really don't
want to base your decision based upon the popular vote in rec.boats.

That's my story and I am sticking to it!

Don't worry Reggie. I did not base my decision on your or anyone
else's advice. I took another look at my Seloc manual again. 160F for
my engine, although the 7.4L and 8.2L Volvo Penta engines take a 140F.
(You previously stated that ALL Volvo Penta's take a 160F).


This is a perfect example of why you should verify ALL info. grin.

When I purchased my first Volvo (it was a 4.3, but I have owned both a
4.3 and a 5.7) I was amazed at the higher temp on the engine versus the
Merc. I had previously owned. The mech. giving me the check out told
me that all Volvo ran at the higher temp.

Very few people would intentionally give bad advice in UseNet, but I
have read as much bad advice (and I mean advice that would have caused
expensive repairs) as I have read good advice.

What was your mechanic's response when you told him about Volvo's specs
on the thermostats?


I then
verified this by talking to a mechanic from another marina.

As I said, thanks to all those who *helped*. Sorry JohnH, you are not
in that group. ;-)
