Is the external oil thermostat rebuildable on a '87?
Mine seems to let oil flow to the front oil coolers and back to the thermostat, but then seems to stop there and not get back to where it needs to.
My temps today were about 190F in mid 40F temps just cruising around.
At the track, the fan never comes on, but it does get up to about 220F on summer days.
The funny part is that I have a manual over ride switch for the fan with a light to know when it's on. Well, I don't turn it on, but sometimes the light comes on any way at the track?
Any help/ideas appreciated.

Hi Jim:
Yessir, it is. Its possible to replace almost all of the internals.
Generally speaking though, if it opens all the way, its usually functional. You can use a hand-held (Raytek) infared thermometer to ensure that the lines are an even temperature.
The thermostat will not open until 185 deg F or so and seeing 190 F is just fine.
Now, once its warmed up,,....as long as the lines under the rocker panel are the same temperature as the lines between the engine & thermostat, your car should be OK.
