The two steel sleeve inserts to the timing cover can be pulled out by hand. If they are stuck, a gentle tap on the joining line between the sleeve and cover usually frees them. If that doesn't work, crank pulley, balancer, and timing cover removal will be necessary to work the sleeves out from the back side.
Electric Fan
Heath Langenfeld of SPAL related, "Since electric water pumps eliminate the factory belt-driven fan, not only is a highly efficient radiator required, but also a high-quality electric fan has to be employed to ensure adequate cooling for the engine, especially when the Pontiac is driven around town. Since the OEM car manufacturers have utilized electric fans and aluminum radiators for decades, enthusiasts can rest assured that the proper selection of components will ensure that even high-compression engines-notorious for running hot-can be accommodated."
We chose a SPAL 16-inch puller fan for our test car. As the supplier to many OEM automobile manufacturers, SPAL's puller fan incorporates a fully balanced and sealed motor that enables it to flow up to 2,360 cfm.
The fan comes with a SPAL thermostat switch, which is designed to send a signal to a relay once it reaches 185 degrees to enable the fan. After the engine cools down to 165 degrees, it signals the fan to turn off.
Alternator Relocation Kit
According to David Butler, "An alternator relocation kit is required for Pontiac owners converting to a Meziere electric water pump. The driver's side kit works on applications without power steering where the passenger side kit is for cars without air conditioning. Both kits relocate the alternator closer to the engine's pulley and virtually eliminate thrown belts at the track."
Now that you have been introduced to the parts and enlightened as to why we chose them, strap yourself in as we install the PRC aluminum radiator, SPAL 16-inch electric fan, Meziere electric water pump and a Butler Performance Alternator Relocation Kit. In Part II, the effectiveness of the new cooling system will be tested under the grueling Texas sun.
A correct '66-'67 housing is installed (with 1/4-inch-headed bolts) because new radiator hoses will be utilized, rather than the existing cut-to-fit ones. The replacement Stant 160-degree SuperStat and gasket will be employed since a new thermostat is cheap insurance against future problems. | 
Rather than utilizing the factory-style alternator mounting, a Butler Performance Alternator Relocation Kit will be employed. Carried for both the driver's side (PN TRP-ALT1, retail $85, as shown) or for the passenger side under TRP-ALT2, the kits come complete with brackets, bolts, a belt and detailed installation instructions. | 
Installation of the passenger side Alternator Relocation Kit begins by mounting the bracket to the cylinder head using the two supplied bolts to loosely secure the alternator. Although the alternator is typically installed after the water pump, it is important to begin visualizing how it will line up with the crank pulley and affix via the swing arm to the water pump to allow belt adjustment. After verifying that the pulleys line up and the swing arm will reach, the water pump is readied for installation. |
Meziere Enterprises produces both a standard and heavy-duty electric water pump for the classic Pontiac engine that uses a '69 and up timing cover. The heavy-duty version-as shown (PN WP103BHD, retail $315.00)-is rated for continuous street use and flows over 40 gallons per minute. | 
The Meziere water pump port adapters must fit into the timing cover securely, so grease is applied to the supplied O-rings. Since the factory steel sleeves aren't used with the electric pump, it is important that the ports in the timing cover are burr and corrosion free so the O-rings seal properly. Next, the 1/4-inch stud supplied in the Butler Alternator Relocation Kit is threaded into the lower left-most hole of the cover. | 
After allowing the RTV that was applied on the supplied water pump gasket to set up on the timing cover for a few minutes, the outer side of the gasket receives a light coat, and the pump is bolted up with the supplied stainless steel Allen head bolts and a 1/4-inch Allen wrench. Remaining fasteners are installed with a 1/4-inch and 1/4-inch wrench. The original water pump-to-cover bolt on the driver's side, which was also part of the alternator mounting, was subsequently replaced with a bolt that was 1/4-inches shorter. |
