Compression Test

[HVAC SuperTech]

How do we do compression tests on our trucks? Is it something I can do in my driveway, or do I have to take it to the dealer or other Garage? I wanna know how my rings and such are, I am loosing some coolant and cant quite figure out where its going. I am not loosing much, just a little bit. Where could be the most common places for it to leak, other than Head Gaskets?

huh? is that some possible faulty parts? The oil cooler seals are where on the truck so I can find them. Thanks

Your oil cooler is on the drivers side underneath, the oil filter attatches to it. There's two gaskets and 4 o rings. The o rings tend to get hard over time and start to leak. If the injecter cups were bad you would be puking out coolant from the resivor due to cyl pressure leaking into the cooling passages in the heads. Snap on makes a nice compression tool for htese trucks, not sure what it costs but chances are alot since its snap on lol. It will thread into the glowplug holes, if you have any mechanical ability at all i think you can check the compression yourself.

I have a snap on compression tester. It has an adapter that goes in the glow plug hole.

Hey Dirko, how much was the compression tester you bought? Can you buy just a regular one and buy the adapter to fit the glowplug hole?

I bought the MT33. I bought it used, but looked brand new for $175 with a bunch of adapters. I think they are 200something new.
