Writing this, I had a few 3M products nearby, forgot the post it notes & Velcro. 

The 3M company was started in 1902 in Minnesota, at the Lake Superior town of Two Harbors. Five men started out to mine mineral deposits for grinding-wheel abrasives. However, developing the grinding wheel abrasives with these deposits proved to be an unprofitable venture. The newly formed company, Minnesota Mining and Manufacturing Co. (3M) picked up operations and relocated to Duluth, Minnesota to concentrate their efforts on sandpaper production.

Times were tough for 3M and the newly formed company had difficulty until it could perfect quality production and a distribution chain. A new investor, Lucius Ordway, was instrumental in moving the company to St. Paul, Minnesota in 1910. Due to 3M’s striving to improve their technical and marketing efforts, 3M began to profit in 1916. 3M Products paid its first dividend to it’s investors at a whopping 6 cents a share.

Northstar Waterpump Replacement – Mechanics Tools

Northstar Water Pump Replacement

Northstar water pump replacement, not so bad with correct mechanics tool

This automotive tool blog features a specialty auto mechanics tool for changing the Northstar water pump. The Cadillac Northstar water pump is located at the rear of the engine. As the picture shows, there is a belt cover over the water pump drive belt at the rear of the front valve cover. The special mechanics tool required for this job used to be only available in more expensive specialty tool brands like Schley Products. If the tool is to be used frequently, the more expensive version of the specialty may be the best choice. If the mechanic only changes a few of these a year, the Lisle Northstar mechanics tool will work just fine.

Remove the air cleaner to access the water pump

Mechanics tools make life easier, in fact without this specialty tool, replacement is simply is not possible. First access the water pump by removing the air cleaner housing and swing the ECU (Electronic Control Unit) out of the way. Remove the water pump drive belt cover and belt. The water pump fits inside the coolant housing.

Access by securing outer coolant housing out of the way

Auto Tools required up this point are everyday, common auto mechanic tools that most mechanics will already have in their tool box. Of course the spring hose clamps can be removed much easier with the correct hose clamp tools as opposed to regular pliers. The professional auto technician more than likely already has a nice set of Mayhew hose clamp tools.

This Waterpump tool is only used on the Northstar. The water pump is a twist in design. The Northstar water pump socket slips in around the waterpump and catches the tabs. A simple twist and the water pump comes out. Be sure that the old o-ring seal is removed. The rubber seal comes out easily, and the good thing is there’s no gasket scraping needed for the water pump itself. Gasket removal is needed for many other water pumps, but this one has a removable seal and it is easy to access. If there is any corrosion build up on the housing this should be removed. Gluing the new seals in place may be necessary to hold them in place for installation.
