On the above vehicles (except for the Mazdaspeed 3), there is the possibility for coolant to leak out at the cylinder head flange.
The following vehicles are affected:
Mazda 3, from 2006 to July 1, 2008
(up to chassis no.: JM1BK3xxxxxx187397)
Mazda 5, model year 2008
(up to chassis no.: JM1CRxxxxxx327438)
In case of coolant loss, special attention should be paid to the coolant flange gasket on the cylinder head (drawing 15-169). It may need to be replaced with a modified variant (LF1F-15-169).
After the repair, refill and bleed the cooling system as per the manufacturer's specifications.
