Hi there i am running bad on my H3 fan clutch as its not engaging fully any more the ac is of and i see the heat gauge goes to 3/4 or a bit more then the 3 mark


VIN: 5GTDN13E478184220
Year: 2007
Make: Hummer
Model: H3 Base / H3x
at around 98K miles

i go often off road and i found the fact there is 3 types of fan clutch on net
Standard vs. Heavy vs. Severe Duty

i need to buy severe duty fan clutch please help me find the exact fit product for my H3
here is a link to rock auto

2007 HUMMER H3 Radiator Fan Clutch

which one you think is better for off road and low speed mountain climbing?

i found this one on amazon

please help me decide which one to buy and guarantee to fit my H3 with the vin given thanks and regards.

 

any of them will do. If rock auto says it will fit then it most likely will, i've never had any problems with the parts i ordered from them. try also this...06 2006 Hummer H3 Fan Clutch - Cooling System - Hayden - PartsGeek.
I ordered this same one... i havnt installed it yet tho. shipping from this company is only $8.95.

 

if you can afford it, I would just go with an electric fan.

 

My gauge runs max 1/2 no matter what the temp is outside! No reason to add an air flow obstruction/voltage usage device(aka:electric fan)! Replace the clutch, upgrade if necessary, or install a "flex flan" if needed, to keep that temp down.

 

thanks for the link bro

 

thanks i don't have money to upgrade it right now i already done many modification and upgrades may be later thanks for the helpfull information

 

i just ordered the HAYDEN Part # 2787 Thermal Reverse Rotation Severe Duty Thermal Fan Clutch

hope it be same rotation direction as my my original fan clutch numbered

part 25948772

here is my car

 

Nice...looks good.

I just know that there is not a lot of room to work with in there. I would just get rid of the fan and clutch for an electric fan for the extra space.

 

Has anybody ever tried one of these flex fans with a late model GM clutch fan truck? I can tell you they will make noise, a bunch of it, all the time non-stop.

I have been running an Efan conversion for 2+ years, solid performance and MPG boost. Never ever come on late fall through early spring.
