At witts end motor keeps getting hot 3.4L. Have been having trouble with it for months I have replaced water pump,radiator,heater core, fail safe t-stat,top radiator hose,bled air,flushed. Ran fine for about three weeks no problems yesterday leaving parking lot I gased it a littile and and not five mins later temp starts rising all most to the red. Acts like t-stat is sticking but this is the third one ran pressure test it was fine. Could something be clogged up somewere ,did I miss something, I'm not losing coolent did notice that the bottom radiator hose is not getting hot like the t-stat is stuck is there some were else that might be restricting flow? About ready to put up for adoption Please HELP

 

How many miles on it? ....since u changed everything else.... ck temp sensors for fan controls...to cool the radiator....or try replaceing the fans and controls....and sensors.......

hope this helps !

 

Could be a failing tstat already, also could be a bad temp sender, if the temp isn't actually that hot.

Have you done a full coolant flush yet?

 

Car has 184.000 miles runs good been a great car. Is there a decent. site to find were sensors are at on motor? Thanks

 

you would think..since he replaced ,radiator,water pump and heater core....etc......

he'd put fresh fluid in it....but ya never know...(good call...Trewyn15)

i'd be curious to see if he actually did use the "old" fluid....

 

I put in new fluid,new cap I'm cheap but not that cheap lol

 

did you flush it or just cap it off? There may be something stuck in there that you could dislodge by doing a flush

 

I meant no disrespect...but there are those that are out there that wouldnt replace the fluid with fresh....

I think a flush is probably the ticket.....

Since you have done everything else.....

But just besure that theres no air in the system....which is a main cause of over heating....when replaceing radiator, water pump thermostats etc...

 

Theres only one way the t-stat goes in rite? I'm no pro at working on motors but I would like to think that I have a enough common sense to figure this out

 

Yes it only goes in 1 way......(suppose to) with the opening faceing up! and the brass side temp sensor faceing down into the manifold (the round copper thingy)...lol.....id post a pic....but im not very comp savy ....lol

HOPE U GET IT RESOLVED....
