Buying And Fitting A Replacement Engine

Buying and Fitting A Replacement Engine

Make sure not to scrimp on the fitting. This is one of the biggest mistakes you can make. You may feel like you have spent a lot on your engine, fitting and maybe a warranty. But when the mechanic says, “I think we need to do your radiator.” You need to listen. Remember that one of the main reason engines fail is due to overheating. In fact it is probably wise to ask your mechanic to do the following:

  • Assess the whole cooling system and advise on need for reconditioning. At the minimum clean and flush the cooling system and refill with new coolant.
  • Fit new hoses to the cooling system.
  • Fit new cooling system belts.
  • Check the replacement motor for its cam belt, see if of course there is one and identify if it may need a new one.  (On many motors this can cause a catastrophic failure if not changed at the correct time.)
  • Fit a new set of sparkplugs
  • Fill with quality oil and fit a new oil filter
  • Fit a new air filter


As pointed out before the engine may have sat idle for some time on the shelf. Generally the engine will be drained of oil when it is put in storage, but never consider starting it without draining any old oil. Some mechanics will even recommend running the replacement engine for a short time and then flushing the oil and replacing it again just to be sure it is clean of deposits of aged oil and contaminants. It is not a good idea to argue with your mechanic on these basics

Another important point on these items is that if you don’t do your cooling system or something basic that the mechanic advises it will likely void your warranty. For a short time directly after the fitting it is important to check under your car after fitting to see that there are no oil leaks. It is also important to check the oil level regularly. Keep and eye on the temperature gauge and head straight back to the mechanic if any thing does not look normal.
