I have seen this many times before. The sound is air being forced out of the radiator cap and escaping back into the coolant recovery bottle. It can be as simple as a new radiator cap or as costly as cylinder head crack, or even block cracked. It is important that your radiator be completely full with proper coolant mix and have a good working order cap with the proper pressure.

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).

Cant find right water pump


Water Pump
This pump fits a 6.5 n/a civilian and millitary HMMWV. Ref 94 Suburban AC Delco 251-589 (Needs Heater 5/8" Nipple 12339396) $120.00
GM part number for 1995 6.5 N/a is 88894044. The AMG part number is 5743241
Pump for a 6.2 n/a is 12534418

Water Pump Backing Plate - AMG 5743232 $96.00
1998 Stud-type water pump pulley amg# 6006809 37.72, gm #12556143.
8 blade fan 6009790 222.81, stud mounted fan clutch for this fan 6009791 153.78
Try these: 96-98 Fan clutch GMC G30 6.5 TD
ACDelco#15-4680
GM#15028400
1999 and up
big-nut fan clutch 6009991, big nut water pump amg#5745093, ac delco# 251-603.
waterpump_fanclutch.jpg The 6.2 and the 6.5 waterpump do share the same basic casting. However, the pump rotors inside the pump are reversed between the two. This due to reversed direction of rotation from V belt to serpentine belt. DO NOT fit a 6.5 pump on a 6.2 or vice versa. If you do, it will not pump water!!!
Thank you , Quinn

Water pump instillation


Remove the Fan Shroud. You have to do this with Both the Old and New Waterpump out. The fan has 4 Nuts that hold it on to the Pulley. Remove these and Remove the Fan and the Pulley. You will need the Studs off of the Old Waterpump and they are Threaded into the Small Circle that is on the Front of the Waterpump Under the Pulley. There is no Easy way to get these off. It is Tough. Then when you are done Fighting with these, Install the Studs on the New Waterpump and Install the Pump. You can do this either with or Without the Fan already put back on. Please Rate My Response! Thanks!

Changing a water pump on a 2005 GMC Pick-up


Open the hood of your truck. Look inside the engine bay. See the fan assembly and the pulley that the belt rides on. The water pump is behind the pulley. Changing water pumps can be somewhat of a task. Professional help will be needed for someone that can't find the waterpump. 


 The water pump is on the passenger side front of the engine; I had to drain the coolant, I kept the belt in place, then I removed the 3 bolts from the pulley to give me access to the bolts on the top (it will require a set of metric tools for it). Then I removed the passenger side front tire and the splash cover from under the car just above the tire, removed all bolts that holds the pump on the lower part of it, then removed the belt, scraped and clean very well the old gasket. The new water pump came with a new gasket, so I just got a gasket maker and applied to the gasket, so I did not have to do it again. Work backwords to reinstall everything, good time to replace the coolant and if you have not done yet, replace the thermostat valve along with any hose that may be cracked, rigid or enlarged (check the hoses to the heater core also). Please check your belts and hoses so you will not have to redo the process again.
