    ok and you need to be careful doing it ... there should be four bolts at the front of that fan... hold the fan blade with one hand while you turn the bolt ...

Sometimes there are bolts on the fan clutch or one big bolt that is reverse threaded and requires a big wrench or special tool to get off. leave belt on engine and hit wrench with hammer to loosen and spin off by hand.

I replaced the clutch fan on my gmc 2003 envoy. But I still have the same problem, the noise is so loud, is there a computer that controls the fan?


you mention you have a clutch fan then you don't have any electrical control on the fan.
remove the belt to see if it 's the problem could be water pump bearing or else
hope it helps

How to change the water pump on 98 GMC Sierra


Michael is correct on replacing water pump but if you are mech. inclined it can be done by removing upper fan shroud and serp. belt only. leave fan on pump until removed. remove 4 15mill bolts and the whole assembly. apply gasket sealer to both sides of gasket and insert 2 upper bolts to keep gasket in place when reinstalling.I have a 1998 gmc and did this a couple days ago while installing injection spider.

How do i remove the fan from a 2003 gmc, 2500hd 4x4 6ltr, water pump?


Hello: Behind the fan and in front of the water pump there is a big nut, turn it counter-clockwise to loosen. (leave the belt on when removing) There is a special wrench for this, Auto Zone, Advance Auto etc) Sometimes you have to hit the wrench with a sharp blow to break it loose.

DO NOT use cooling system seal tabs (or similar compounds) unless otherwise instructed. The use of cooling system seal tabs (or similar compounds) may restrict coolant flow through the passages of the cooling system or the engine components. Restricted coolant flow may cause engine overheating and/or damage to the cooling system or the engine components/assembly.

Install or connect the following:

Water pump. Install the water pump bolts. Tighten the water pump bolts first pass to 11 ft. lbs. (15 Nm); tighten the bolts final pass to 22 ft. lbs. (30 Nm). Water pump drive belt pulley and bolts (if applicable). Tighten the pulley bolts first pass to 89 inch lbs. (10 Nm); tighten the bolts final pass to 18 ft. lbs. (25 Nm). Surge tank hose Heater hose Outlet radiator hose to the coolant pump Drive belt Cooling fan and clutch assembly Upper fan shroud Inlet radiator hose to the water pump Air inlet duct Coolant

Only cools when driving instant warm when i slow down


I would check your water pump and clutch fan. There should be a weep hole under the water pump that will start to leak when the bearing starts to go.

2000 gmc sierra 2500 the engine temp rises when stopped. It has a 6.0 V8 i also noticed the transmission temperature is going above 200degrees, thats never happened even hauling loads in texas heat


Just guessing but, I'd say either fan clutch is going bad, not turning as fast as it should be once temps go up or if you have electric fans, either fans or relays bad. I'm leaning more toward the fan clutch. The fins on the impeller of the waterpump can also wear done over time and reduce the amount of water flow.You may also want to make sure the fins in the radiator are clean and not stopping air flow. I'm assuming that when you're moving there's no problem so that should say that water pump, thermostat are doing good. Please rate this. Thanks
