I have a t100 that keeps overheating we replaced everything from the water pump timing belt thermostat and it still overheating can you help me

Connie, Were the radiator,water pump and thermostat replaced to try and fix the over heat issue or as maintenance. Engine overheating can be caused by a lot of things, Leak in cooling system, air in system, bad rad. cap, slipping belt, faulty thermostat or installed upside down, faulty water pump, plugged radiator (inside/outside), collapsing rad hose, faulty cooling fan, leaking head gasket, sludge plugging engine water passages, poorly tuned engine, etc..
Take into a good shop for diagnoses and estimate for repair. Check the attached links,instruction and guides, Good luck

overheating sound like faulty thermostat.thermostat either sticking close or could have blown headgasket if you see a lot of white smoke coming out of exhaust.if headgasket is leaking check engine oil should look milky.also check water pump look around weep hole or see coolant leaking around water pump replace water pump.also check water pump drive belt.make sure drive belt not loose slipping.

A few questions first...are you sure its overheating and not just a bad temp sensor? is yes then how many miles on car? if over 90K than did you have the water pump replaced with your timing belt?Is your fan coming on at all? Is your radiator full?If your water pump has been changed and your radiator is full and your fan is working properly and you have a new thermostat then you should take your radiator off and have it flow tested to make sure its operating properly, and no you cant just pour water through it to tell if its working properly.

if the thermostat is broken the fan should keep turning. Check the fan if it spins once you get the car warmed. Otherwise it could be a blown fuse or relay for the fan or the fan itself may be bad. Check the radiator hoses and the radiator cap for loose or worn parts. Steam may escape there decreasing the water in the cooling system. The problem could be also be with the water pump. If you are to replace the timing belt have the water pump replaced since you will spend the same effort getting to both the timing belt and water pump. It is recommended that this be done by a specialist to avoid damaging the engine.

The symptoms would be the car overheating and not cooling down, Also in some cases the water pump will leak. With a overheating problem its always a good idea to check the thermostat before jumping to water pump. Hope this helped =)

Overheating can be numerous things: Fans not working, water pump, thermostat, overflow cap, and the list keeps going. When the engine is running and heats ups, feel the heat of the top hose, if the hose isn't hot, the thermostat is most likely stuck open and needs replaced. If it is hot we know you have circulation. The cap on the expansion tank may be defective, if it can't hold the pressure of the water, it will release at the overflow cap if the cap is bad. Also check the coolant level.

This is very vague and hard to diagnose without more detail. I have a hunch the the brakes "locking up" is a different problem than the engine overheating. To check the engine: Remove the radiator cap from the cold radiator. Be sure the radiator in almost topped off with 50/50 antifreeze & water. Start the car and let it idle until either you can turbulence in the radiator, or the engine is getting really hot. Is the water temp gauge working? You can keep an eye on it during the process. If you see turbulence then the thermostat is opening, and the water pump is pumping. The thermostat is fairly easy to replace. The water pump is lots of work. Usually the timing belt, tentioner, pulley, and accessory belt is changed at the same time as the water pump, because the labor costs more than the parts. Hopefully nobody ever put straight water into the radiator. It causes corrosion, and lots of related problems.

Remove and raise upper hose at thermostat end and remove lower rad hose.
Fill rad with a hose and watch for flow from bottom rad hose and/ or bottom rad hose connecton.......water should fall though rad easily.
Honda rads are cheap.....any restriction....replace rad.

Remove thermostat....fill thermostat housing with hose and watch for water flow at bottom rad hose.
Flush good.

Remove heater hoses.......flush back and forth until a good flow is present "With heater control set to hot" if no or poor flow....replace heater core.

Stop leak can plug everything.

Also.......not likely causing over heating....but ....at your mileage,if you do not know if the timing belt has been changed.....CHANGE IT NOW!
Water pump is optional at this mileage.

replace radiator cap system depends on good pressure to keep from overheating

Safe bet on a timing belt is every 60k miles. Remember it's not just the belt - it's the tensioner also, as well as the water pump, thermostat, spark plugs, spark plug wires, all fluids, all filters, brake inspection, tire rotation, and an inspection of lighting and suspension parts. Plan to pay quite a bit if you don't do it yourself.
