View Full Version : '88 B2 overheating -- need ideas

08-23-2005, 10:04 AM
Buddy of mine bought himself a '88 BroncoII.
2.9 5spd standard.

Everything works good except when he runs at freeway speeds (on the flat, no hills) it gets HOT.

Drivin' around in the hot, hot city all day no prob but after a few kms at highway speed the guage goes to the top.

Any ideas????

fan clutch maybe? If its not working right the fan might be siezing up at speed and blocking airflow through the rad.

It is a really small single core rad with a much bigger a/c condenser in front of it.
The a/c does not work so I suggested he start by removing the condenser for better air flow.

I had that probklem till Nick suggested my fan clutch ! Replaced it and it runs great now ! I would never have guessed it would be that simple !

Consciousness: That annoying time between naps.

Sounds like a simple fix.
I'll pass it on to buddy.

Any other ideas in case that isn't the problem [?]

cut the roof off-that makes them cool.

sometimes when i'm tired i'll be rude to people...the rest of the time it's just because i think it's funny.

u can check the fan clutch it is easy to diagnose

check the thermostat as well remove the condenser

and pua dual core rad in...

the 84' b2 had a 3 core rad if it needs a new one

what good is it if you can never think of what to put here

i agree with the clutch fan it sounds like its not spinning up

The first thing I told him to do was wash out the condenser and radiator 'cause ya never know what the previous owner has been up to....could be full of mud.
He said no he could only see some bugs in the rad.

Well................he finally pressure washed the rad and condenser and now everything works fine.

every vehicle ive ever had with clutch fan problems would overheat when idling or in city traffic when the airflow was low from the vehicle moving slow and the fan not fully spinning up, and it would run great on the highway when theres lots of air through the rad due to the vehicle moving through the air fast....so it doesnt sound like the clutch fan..maybe the vac advance is not working (or leaking)and is causing lots of heat at high rpms due to retarded timing ??? I might be off track, but its a cheap fix if thats all it is.

I prefer to think of us as a Drinking Club with 4x4 problems !!

replace it with a rad from a 4.0L explorer or ranger, its a pretty comon swap these engines like to crack heads if you over heat them so dont neglect it too long.

Im multitalented I can talk and piss you off at the same time...!

Your point is?
