Damaged cores can be repaired no matter what the shape it maybe in, repair cost will be subtracted from the $1000.00 core charge deposit.

Prior to sending out the rebuilt water pump, pictures of your pump are required for verification. and to confirm the type of fan hub you have and the position of the hub on the pump shaft for proper fan belt alignment.

If the deposit is too much or for any other reason, you can elect to send us your pump and we'll be happy to rebuild it. Just use the rebuild option, part number 255368-00 and you can proceed using that option.

It is not our desire to make this process complicated or expensive but due to the scarcity of these pumps we have to maintain strict control of the cores we have so others will have the opportunity for a rebuilt unit.
