hey everyone i have a 94 ranger with the 4.0 in it.... i got in an accident about a year and a half ago and i got my truck fixed i never really noticed anything until yesterday but when i got my truck fixed by a local shop i guess they put in the 2.3L fan in my truck i have noticed my truck has been running hot but i just thought it was normal i have the 180* thermostat in my truck also is this fan a problem and do i need to go get the fan for the 4.0?? or is it really not that big of a deal

your thermostat maybe going bad, my truck did the same exact thing your doing and it just got worse and worse till it overheated and fried some sensors, I would replace that like now because its cheap and easy to fix, to fix all the sensors i fried was over 500

is it overheating on stand stills or while moving?

could be a water pump or alot of things.

when im moving it cools down but when sitting still it starts to get really hot i dont think it could be the thermostat it is like brand new maybe 3 months old at the most

how many miles and is your check engine light on?, you could always put washers in between your hood and hinges lmao

please i pray you dont do that

could be a bad fan clutch.

what james said

do this, after driving for a little while, park your truck, and let it idle, pop your hood and see if your fan is spinning with the motor or if it is free floating

if thats not it replace the thermostat

Mine does that same thing he's talking bout at Idle my temp goes up pretty quickly then when I start to drive it it goes back to cool

i have a little bit under 110,000 and no my check engine light isnt on... somebody i know was saying it could be the water pump is this likely??? but if i cant fix my problem i think im gonna raise my hood with some washers lol i think thats a great idea haha nah im jk i wouldnt do that if i had to lol but seriously thank you everyone soo much for helping me out

if your pump is shot, the seal under the pump would break and you'll have coolant leaking all over the place from the pump itself....it may just be on its verge of going out, but if it was, it would be over heating overall, no matter what RPM the motor is turning, not just at idle

at idle, the fan clutch is suppose to engage to spin the fan to cool the motor, once you are up to speed, it will disengage, thats the purpose of the clutch in there...if it does not engage, then that means it'll typically heat up during idle

a bad thermostat will make a truck overheat also, but it'll make it overheat overall just like the waterpump will...if it goes bad, it'll overheat no matter what RPM or how fast you are going. thermostat can go out in 2 ways: not opening , or not closing. If the T-stat does not open, then thats when you will have overheating problems, if it does not close, then thats when it takes a bit longer for the truck to be at running temperature which does not hurt anything unless it is winter time because it'll take awhile for you to get heat.

your best bet is to check the fan clutch, if that is engaging, replace the T-stat, if that doesnt do it, replace the pump (but you will see if the pump goes out, because there will be coolant gushing out of the seal under the pump)

not nessarliy bout the pump mark the bearing could be going out and it not cooling untill the motor spins it faster. the water pump on my 3.0 was leakin grease outa of the weep hole( lil hole in the neck of the pump)

oh aight, yea thats right
