how much to replace the engine

I bought a rebuilt engine for 2300.00 they ship it to you and then you return the old one it is not that hard to do an engine swap I am 60 yrs old and just did mine it took me a week to complete it. they also recommend you replace the oil cooler could only find one at a dealer . while doing the engine you will want to replace the belt, and rad hoses, thermostat, and transmission fluid and filter, clean the throttle body and oil pan New gaskets come with the engine rebuild there is also new oil and filter and antifreeze you will need So the total is going to cost you 2600 if you do the work you will need an engine lift and leveler to lower and raise the engine back into the van

rebuilt motor 3500-3800 used motor 3000 Roy
