Question about 1988 Honda Accord 4 Door
You'll find the thermostat behind the valve cover almost all the way to the left. It will be just underneath the distributor. You will need to disconnect the main upper radiator hose, two electrical plugs and three mounting bolts. This will remove the cover. The thermostat is approx 2" wide and circular. When installing the new one, be sure to have a proper gasket (my new one didn't come with one) and set the temp pin at the top when re-installing. (The little loose piece of metal) You may have to move a few things around to get to the case. The big hose to my air filter was a real pain, but I was able to disconnect it from the filter house and just push it out of the way. There may also be some wiring you'll need to shift around for access. All you'll need is a standard ratchet with a 10mm head and a 3" extender, and a pair of plyers to pinch the hose lock. When you're done, put everything back where it was. Careful not to overtighten the bolts, they WILL snap. If possible, the ideal solution would be to use a torque wrench and use the specifications found in the repair manual. But if you're careful about overtightening, you should be okay.
