Lisle Auto Tools manufacturing company was started in Clarinda, Iowa in 1903 by C.A. Lisle. The first tool his company manufactured surprisingly wasn’t an automotive tool at all, it was water well drilling equipment powered by a horse! Subsequent products were not automotive related either, remember old ringer washers? And how about the old style manual push mower? Some twenty years after the Lisle Corporation was first started, the tool company made its first automotive product.

New Specialty tool for handling Ford broken spark plugs!

If you’re a subscriber to our automotive tool blog, you know we pointed out in a previous post, the need for a less expensive alternative to the Ford Rotunda 303-1398. The SPX Rotunda 303-1203 removes broken spark plugs on some Ford 5.4 engines, 2004 and up. But it only works after the broken porcelain piece is out of the way. That’s where the new Lisle LIS 65600 automotive specialty tool, comes into the picture. The best way to try to prevent Ford spark plugs from breaking to begin with (per a Ford Technical Service Bulletin-TSB) is to loosen the spark plugs slightly and then soak them with penetrating oil. Sometimes the carbon build up around the electrode shield will still separate from the main part of the spark plug. So, in many cases the porcelain part of the spark plug will stay in. This prevents the use of the 303-1203. Rotunda offers the SPX 303-1398 to remove the porcelain or ceramic piece, but the pins included in this six hundred dollar kit can only be used once. The pins are secured into the center of the broken spark plug (where the electrode was) with loc-tite, then the puller is used to hopefully pull the ceramic piece out of the way, so the two hundred dollar 303-1203 can be used to remove the metal electrode shield.

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.

Northstar water pump revealed

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.

Automotive specialty tools like this makes certain jobs a piece of cake. Without this specific mechanic tool, the tech finds himself down the creek, well you know the rest.
