where is the thermostat located and how do you replace it located on a 1990 toyota camry 3s-fe 4 cylinder?
general procedure: make sure the engine is cool. loosen hose clamp where lower radiator hose attaches to engine - pull forward. place clean pan under hose to catch coolant that might spill out. pull hose off. catch coolant in pan. remove bolts on the fitting that the hose was attached to. remove gasket. remove thermostat (note how it was positioned and which side was facing out before removing -- there may be an alignment notch). install the new thermostat (the way the original was sitting,with the little "barbell" at 12:00) and gasket. re-attach hose fitting w/bolts. re-attach hose and clamp. put coolant that spilled out back in radiator. start engine and allow to warm up and check for leaks. note - if you need to remove your alternator so as to access the nuts holding the thermostat cover remember to disconnect battery before removing the alternator leads to prevent shorting. good post on parts location and repair procedure. only thing i'd like to add is antifreeze has a limited life before it loses it's ph balance and will turn acidic or base, either one will cause corrosion in the cooling system. loss of additives can also cause the cooling system to start acting as a ground conductor which will damage the cooling system. there are many different ideas on when to change, i try to change mine every 3 years or 24k miles. if you want there are test strips to check ph balance, protection temp and phosphate levels (prevent oxygen molecules from collecting around cylinder liners and etching them - usually more problematic on diesels). hth, dave
What tools do i need to install a drive belt in a 1996 ford windstar 3.8L engine and is the tensioner spring loaded or do i need to undo any bolts The reset button is located behing a panel on the front of the unit that is labeled Heat Reset. If that label is gone then look around, it is a small hole, small enough for a paper clip to fit through.   

 That being said, I have 137 of these units in one of my hotels and have not had a single one needing to be reset. You probably are going to need a new control board kit. These can be purchased from Amana. They are $130. Make sure that you have pulled the heater coil out and inspected it first. Also, there was a recall years ago where Amana was supposed to contact and send out new voltage switches. These are the round black things that the Brown heater wires connect to on the upper and lower side of the heating coil. You should also try to replace those if you find the coil in good condition. I have had those resolve heating issues. Most of the heating issues were a result of a bad relay on the control board though.   

 Please remember to rate this fix. hey @richard cookehave you seen our community post about the hive thermostat offer?is there anything in there that helps? see owners manual. In the middle of the TT youll Find a C-Clip It needs to be Removed before the Platter can be removed,You either have a Broken Belt,Or the Grease in the Guide is Old and must be Cleaned out and Relubed the latch head (the part you describe) is ref # 5-7 in the parts list and is part # lstppa169wrf0

(that's a zero on the end, not an "oh")

i appreicate your rating. good luck! No friend, it isn't by the air filter. It's the unit that is connected to the intake and the air filter flex hose goes to it. This MAF is mass air flow, and there is a wire across the venture of the unit on the inside. First, purchase a can of Mass Air Flow Sensor Cleaner from an auto parts store, CRC makes this spray cleaner made special for this sensor. The sensor IS the wire that runs across the venture of the MAF. Take the MAF unit off the manifold and air line from the filter, it just bolts on, keep your fingers and anything else away from the sensor, and spray it real good with the MAF Sensor cleaner. Spray the venture also to clean the bore of the unit. Put it back together and if, in fact this MAF sensor was the problem, the cleaner spray will have taken care of the situation. brother, you better get a manual. i think they teach a course in this at the local community college. seriously, i can't responsibly explain the procedure to you in a venue like this.

actually, the nummi (new united motor manufacturing, inc.) plant in freemont, ca has been in operation since dec. 1984. the web addy is www.nummi.com and the solid address is:
new united motor manufacturing, inc.
45500 fremont boulevard
fremont, ca 94538

toyota and gm have made several vehicles there, starting with the corolla/nova, then the corolla/prism, then the matrix/vibe. toyota has also produced the voltz, a low production vehicle only sold in japan, and the hilux pickup that evolved into the tacoma.

the tacoma, matrix and vibe are currently built there and it has been a great deal for both companies. in the early days, nummi gave toyota a strategic manufacturing location in the us and gm got access to good, small vehicles that they didn't have to invent from scratch.

now, toyota has eleven major manufacturing facilities in north america and canada and dozens of smaller supplier locations, so nummi has become just one way for toyota to meet the demand for corollas and tacomas.

the matrix and vibe, while built on the same base platform, are not the same vehicle. the matrix has thicker glass, more insulation and sound deadening, is offered in three trim levels, is offered with four-wheel drive, and has more extensive and more advanced safety features (four-channel abs that controls each wheel independently versus gm's two-channel abs, for example). for 2008, gm only offers the vibe in one base trim level and only in front wheel drive.

the matrix is based on the corolla platform and the corolla is being completely redone for 2008, so gm may or may not have a vehicle based off the new corolla. seeing how gm has pulled back on how the vibe is offered, i would expect them to wait and offer a totally different vehicle once the new corolla is out. i would expect that new vehicle to be some sort of crossover/wagon type of small car, looking at current trends.
