Do you have an electric fan and does it come on?

mobilecherokee4

i wired it to a switch so its on all the time, i think its my belt driven fan, since it dont have a fan clutch i thinks thats whats wrong with it, what you think?

You don't have to have a clutch. Personally I don't like them and if I am having heating problems, they are the first to go.

You will have to help me a little with narrowing it down. For instance it could be your alternator bearings , which are near that location.

IS there a specific time it happens like when the ac is on when it is hot when it is cold. Is it a constant noise or off and on

mobilecherokee4

i dont use ac but it works, the noise is all the time, and yeah i think it might be some kind of bearings, im just not sure

a1racer

The easiest way to find it is pull the belt and check every moving part for grit or frozen bearings.

yeah ill probly work on it tomorrow, im gonna buy a new fan clutch, the thing is sometimes it overheats and sometimes it dont,it will stop at like 220 them sometimes it will be at 210 (which is ok with me) but today i was on the interstate and it went almost to 260!!!! then all of a sudden it dropped back to 220?????? somethin is really weird, do you think my hoses cant take the pressure and are colapsing or somethin??

a1racer

At this point I would flush it get a new t stat and replace the hoses and the colling should be set and yeah replace the fan clutch if you don't think it works they are not a lot of money to replace.

mobilecherokee4

well hoses are fairly new but i might get some heavy duty performance ones not sure yet, def a new t-stat and def fan clutch, and i got some stuff to flush out the radiator, what is setting the collling?

a1racer

Sorry my phone doesn't like some words I type I mention after that the cooling shoud be all set and working good.

mobilecherokee4

oh ok thanks man ill work on it today and let you know how it goes

mobilecherokee4

well fixed the noise and cooling problem with just a fan clutch! it runs under 210 now!!! i also plan to flush out the radiator and clean everything, oh and thanks A1 for all the advice!!

a1racer
