A 180 and a 170 degree thermostat are listed for it.
If your 93 Nissan Pathfinder transmission won't shift into overdrive, check the transmission fluid levels. Ensure the fluid is at the proper level.
rocker arms wont open valves all the way for proper fuel air mixture
I assume where it has a 195 degree thermostat that operating temp should be in that range 190-220
If it's had proper maintenance since new, you should expect 180,000 - 200,000 miles out of it. With excellent maintenance, alot more.
open the radiator cap to release any pressure from the system. Follow the top hose from the radiator and unbolt the two 14 mm bolts holding the thermostat housing in place. Remove the thermostat out of the housing. I replaced mine with a fram 195 degree fail safe (when fails stays open not shut)thermostat. Reinstall making sure you use proper gasket and proper thermostat.
The spark plug order for your 1988 Nissan Pathfinder V-6 engine is; one Êsix Êtwo Êfive Êthree Êfour. Your engine will run very rough if the spark plug wires are not connected in the proper order.
All cars need a thermostat for proper operation and longevity.
Yes, the thermostat needs to be installed for proper engine operation.
The 2007 Nissan Pathfinder takes a special 12" rear wiper blade which can be hard to find (see link below). Always be sure to lookup wiper part numbers by vehicle make, model & year in the books in the stores or google lookup wiper size online. This will ensure not only proper length, but also the proper attachment (which many people overlook).
If the thermostat is stuck open, the engine will never warm up to proper temperature.
You don't tighten it. It has an idler pulley that keeps the proper tension. If this is an old belt and is loose, then it needs replacing. If you have installed a new belt and it is loose, then either you installed the wrong belt or the idler spring is weak and the idler needs replacing.
What is the proper way to annotate a masters degree behind your name? Thank you.
