This is one cleverly designed tool. Could not have done it better myself. I actually use to make a couple different types before I found this one. If you have ever tried to remove a radiator hose corroded to an alumium housing you know what I am talking about and you will love this tool. Great when changing radiator hoses, especially the short hose. 8 inches in length.

It will get those stuck radiator hoses loose and off in seconds... 

I like this - permanent - threadlocker because it is super strong but can still be removed with a heavy handed breaker bar. This is a very large bottle for the price and is a must have for Mercedes diesel owners. I use it anytime I am doing major repair work on an engine or transmission. Great for front crank bolt, cam bolt, torque converter bolts, injection pump mounting nuts, front engine accessories, brake caliper bolts, front suspension, etc. Anything that you can just not afford to come loose.

This removable thread locker is probably the best that I have used. It has the best sealing cap and cures rapidly and reliably when confined between metal parts. Use it to lock threaded fasteners, nuts, bolts and screws from loosening. Extremely important in critical engine and suspension parts. This is the removable type (meaning that it can be easily removed with hand tools). Comes in small .20 Fl oz. bottle great for most small jobs.

Excellent for all work around diesel engines to prevent vibration failure and breakdowns. If you need the red more permanent type CLICK HERE.

This permanent thread locker is probably the best that I have used. It has the best sealing cap and dries hard in 20 to 60 minutes. Use it to securely lock threaded fasteners, nuts, bolts and screws from loosening. Extremely important in critical engine and suspension parts. This is the permanent type (meaning that it is possible to remove only when applying heat to 450 degress F - with propane torch) or a very heavy breaker bar. I like to use this one on brake caliper bolts as it is such a critical bolt.

Excellent when retaining bearings and bearing races, freeze plugs, rocker arm and main bearing studs, etc. Can fill gaps up to .007 and assures positive controlled locking.

Fits all 5 cylinder turbo diesels from 1978 to 1985. Believe it or not these do go bad! If you live in the rust belt (ie salted roads) the lower alternator mounting bolt can actually seize in this bracket. When that happens the only way you will be able to remove your alternator is by cutting the bolt with a saws all and metal blade. Then you will need a replacement bracket like this.

I like to use plastic inline filters to monitor the flow and quality of the fuel (yes you can even check for air in the system). The filters that have proven best for this application are Mercedes diesel pre-filters with brass insert ends for greater strength at the nipples. These filters do the job but are only available for 5/16 or 8 mm fuel hose. I have solved that problem by adding an alcohol resistant and very tight hose spacer on the end of each nipple. This in effect will allow you to use 3/8 inch fuel hose without deforming the hose or allowing leakage. These filters have the 90 degree nipple to allow you to fit it into tighter places.
