Ford 7610 Thermostat

Hurst · Apr 22, 2015

Quick question for you guys... I replaced
the thermostat on the 7610 we have while i
had the coolant system drained to check and
set The pump timing because it seemed to be
running cold. The local ford mechanic had a
replacement in stock. It was a 168 degree
one which matched the one that came out
(both had 74 stamped on themail which I
assume means 74 degrees Celsius). Does this
tractor need a 190 or 203 degree thermostat
instead? I noticed the parts manual shows a
203 degree thermostat, but that is also for
an 87 and later. It doesn't show the
earlier tractors. Mine is an 86. Pulling a
20' batwing yesterday pretty much working
the snot out of the 7610, it never got much
above 160 degrees F.

I should note that the temperature reading is from a new mechanical gauge I installed on the tractor since it has some issues with the cluster gauge.

I ALWAYS run an 88C (188F) deg stat in all of mine, regardless of their age. I've always found that Basildon engines will not pull if you run them too cool, and by that I mean a 168 is too cool. I don't remember if yours is of the age where it has that whacko 100 buck stat in it or the more basic type... hopefully it's the more basic type in the elbow.

Rod,

It has the thermostat that you take the elbow off and it mounts against the head. It sits sideways, not flat, if that helps. Is it something the local napa should have? I'd like to get it replaced if at all possible while it is raining today, because once the sun comes out, it's going to be a battle to keep the grass at bay!

Probably most auto parts places will have it. Those were a pretty common Ford thermostat at one time.

Thanks for the tip! It is the same as the old 302 used for sure, and I think quite a few chevy engines of the same era. I put in a Stant 13359, which is a 195 degree F thermostat. It fit perfectly (actually better than the one that was in there the was a little loose in the cutout on the elbow for the thermostat). Now the tractor gets up to 170 without much pull and pulling 180-185 (It was in the low 50's yesterday here, so it should get a little warmer as summer arrives). It still is a cold-blooded beast, it seems. Takes forever to warm up!

Where did you put the new temp sender?

Hurst · Apr 23, 2015

I put the sender where the electric sender for the stock gauges goes. This is the tractor that had the cluster replaced with the wrong one (older style) so none of the gauges worked. I just mounted a mechanical temp gauge to the top of the dash so I now know if my tractor is overheating or not.
