Your question needs a little more clarification. As far as bolting it in....nothing. They are pretty much the same engine. Are you replacing a 2.8 with a 3.1 that has the same fuel delivery system? Are you using one with the same computer control generation?
You can replace your 1998 Buick 3.8 liter engine with a Buick 3.1 liter engine. You will need to change the motor mounts and some of the wiring harness will need to be modified.
Yes. However make sure you replace the HO transmission as well. There may also be some rewiring that will need to be done as well. Also, replace the U-joints on the drive line for the upgrade.
Not without a lot of work. You will need to replace the motor mounts, ECU and transmission. Far from a direct swap.
Yes , the 3.0 liter SOHC - V6 engine in a 1999 Dodge Caravan has a timing BELT . Replace every 60,000 miles according to the Gates website
In the fuel tank may have to be removed for access
You probably need to replace the crankshaft seal
Yes but you will need complete wiring harnesses and the ecm for the 4 liter v6 that's the only way.
You can replace with a 1.6 from a Tracker or even a 4.3 liter Vortec V6. For diesel, 1.8 to 2.0 liter older VW engines can be swapped as well. Most of these need some adaption that is readily available.
I've replaced one before, you don't need to lift the engine, but there is some there is some crazy angles to work with.
Head gaskets do not go bad on these. You need to replace the plastic upper intake manifold as it is leaking coolant into the combustion chamber. Common problem for this engine.
no you will need to change the trans no you will need to change the trans
The whole thing my guy
