Bet the new fan clutch solves your problem.

 

[GMJoe]

Man, I sure hope so. Stupid vehicle is running really good.
I have the fan out now, is there anyway to test it outside the vehicle? Hub seems tight, can spin with hand but doesn't continue spinning.

You dont seem to have tested the temp at the housing in/out.. Have seen that thermostat installed backwards several times, the normal flow on these engine is backwards,,, feeds the hot ware via the cab heater then to thermo...

Humour the old man.... LOL!

 

[GMJoe]

Yes Phil. Thermostat is in correctly. Even though I made sure I had good flow through the heater core and I can seem to idle all day in the garage with good cab heat and only overheat and lose cab heat on an actual test drive, my next test is to bypass core to see if it only clogs under load.
I'd much rather change a head gasket than take apart the dash though.

Maybe

Not sure I trust it.

Read the entire thread, Did I miss a part where you CONFIRMED that it's not a head gasket? Did you use a 'funnell fill' when adding coolant? And you ran it for a while to completely purge the Air. I have a 2.3 in a Sport and idling, even with it on ramps to get the front up it still held air. I had to run it for a while at 2500rpms and then the bubbles FINALLY came out. Idling, even on ramps won't purge the air. Reading this and all you have checked, and not 100% ruling out the head gasket with a hydrocarbon test is putting you where you are now. frustrated.

GMJoe, did you ever figure this out?

 

[GMJoe]

Waiting for a clutch fan. I bypassed the heater core to rule it out or not. Not putting old fan back in because I can stop it with my finger while engine is idling.
Tired of driving daughter to work and no doubt, so is she.

 

[USMC5811]

You are awfully quiet lately.

 

[GMJoe]

Got fan clutch today. Installing tomorrow. On vacation for next 3 weeks. Gonna get-r-done before back to overtime.

don't forget bandaids and good selection of swear words, you will drop at least 2 nuts.........

 

[GMJoe]

Yeah, still trying to break that habit.
About the nuts; there's just not enough room to use the ratchet end wrenches because their to close to the hub or it wouldn't be a problem.
Thank God for magnets! Lol.

 

[2013GV]

thats why they invented open end / ring spanners without ratchets, 1 flat at a time and feel the blood pressure rise hehehe

Don't you have someone with small hands to start them and run them down finger tight? If not your toolbox is not complete.

I used to have such a device in the toolbox, sadly its grown up and keeps stealing my car keys, and returns the car with an empty tank.

 

[GMJoe]

Nope, they're all gone. Now I have to use rubber bands.

 

[Kalahari]

GMJoe,
Much easier way of fitting fan clutch assembly is to mount cooling fan together outside and mount both onto the cooling fan pulley, part no. 17140-77E06. Now with one hand you hold fan, slide down into position and use other hand to put both bolts through bracket connecting against engine block. You do not lose any nuts like that, just tighten belt and you made it.

[USMC5811]

GMJoe, you back yet?

 

[Colin Morris]

Hi GMJoe, I would be replacing the bottom radiator hose . I have had a similar fault in an old ford in the past and eventually found the bottom hose was starting to laminate. The outside of the hose held its shape and the inner was sucking in creating a flow obstruction on the suction side of the water pump. Changed the hose and in my case the problem was solved. Good Luck.

 

[USMC5811]

Joe, come on, Inquiring minds gotta know!!! How did it go?
