Check to make sure its the correct thermostat, if its the wrong one the housing will not mount flush and crack when you tighten it.

I just replace the thermostat in my 1983 ford f150 and the coolant is topped up and my gauge says am over heating does anyone have any ideas

you probably have air trapped in the cooling system. Lave the cap loose and warm up the engine till the thermostat opens and top hose is hot. Shut off engine and tighten cap and keep reservoir to full level. Refill as it sucks back into rad.

How do u replace a fuel pump on a 83 f150

  • To replace a mechanical fuel pump, remove the inlet and outlet lines at the pump.
  • Use a plug to stop the flow of fuel from the tank.
  • With the correct size socket wrench, remove mounting bolts. Then, remove the pump from the engine.
  • Clean the old gasket material from the engine block.
  • Apply gasket sealer to the mounting surface on the engine and to the threads of the mounting bolts.
  • Install the new gasket, then position the pump by tilting it either toward or away from the block to correctly place the lever against the cam.
  • If the pump is driven by a pushrod, the rod must be held up to permit the rocker arm to go under it.
  • When the pump is properly positioned, there should be an internal squeaking noise with each movement of the pump.
  • Tighten the mounting bolts firmly.
  • Attach the inlet and outlet lines, start the engine, and then check for leaks.

How to Change a Thermostat in a 1999 Oldsmobile silhouette

Hi to change your thermostat ..disconnect your battery .follow the top rad hose to you motor .where the hose connects to the top of your motor there is a thermostat under neath the thermostat housing remove rad cap ..when cool only ....drain rad ,bottom of your rad there is a bleeder . use a good leak proof container to keep antifreeze from going on the ground ...if you spill any ..make sure you wipe it all up is very poisonous to small animals ect
You will have to gain access to your thermostat ,so remove all things that are in the area where the hose goes too ...the motor .First remove the hose connected to the thermostat housing ..remove thermostat housing ...usually a few bolts ....under neath there is a thermostat ....and a gasket ..once you remove the thermostat sure to put the new one back the same way you took the old one out ....plug the hole with a small rag ....any extra rad fluid spilling on the motor ect ...wipe it up it is corrosive wires ect
Before changing the new thermostat ...use a scraper to clean the area where the gasket sits ,put a small cloth in the whole before you clean to make sure you don't leave any dirt in the hole ...i usually use a shop vac to clean the area after i finish scraping the area ...
buy a good gasket sealant thermostat should come with new gasket ....put new gasket sealant on the gasket so it will not move while trying to install the thermostat housing,be sure to line up the holes in the gasket where the bolts will be installed later . Place new thermostat in then your new gasket the hole .also remember to clean the thermostat housing too ...before reinstalling ....tighten bolts by hand first hand ,use a ratchet....after tightening ....tighten about a half turn ...don't over tighten ,you could break the bolts ,and it's not good to over tighten because of the new gasket also ...put back rad hose to thermostat housing tighten well ,then tighten bleeder on rad ...if you havent changed your antifreexe in some time, buy new antifreeze ..if you are not sure how to mix it pre mixed antifreeze,fill rad ,connect battery ...start motor ....set heating controls to max ...and blower to the highest setting ,keep filling rad while motor heats up will bubble some ....once you feel the rad is completly filled ...put rad cap on properly your resorvior where you put antifreeze in, fill it to where it should be filled too ..there is usullay a mark to tell how much it can be filled to .check inside your vehicle to see if ther effecient heat comming out your vents .it might take a few days or so for the air to come out of the rad ...ect ....also in a day ..check to see if there are any leaks ...tighten things up more if need be .....
good luck ...let me know how you make out ...
Just to let you know can buy an all season thermostat so you will not have to change it every different season from summer to winter ....

2001 Ford F150 5.4 engine water leak on top of engine under intake

I have read a few complaints about the plastic intake manifolds leaking. There may also be a heater hose on the rear of the engine leaking. You may be able to tighten the bolts starting from the middle and across then equally front and back. I do not have torque specs. but you may not have a torque wrench. You may get away with just tightening the bolts and not having to disassemble anything.

Go to an auto wrecker. Take the broken one with you and try to find the right one. Somebody may have changed the head or the whole motor on that truck at some point. Maybe you're getting the wrong parts because of it.
