HELLO, Need help finding out about an engine replacement in my wives car back in 1996. It is a 1990 Corolla that had a Japanese motor installed with 40,000 miles on it. There is a 5A and numbers stamped on the case which means it is a 1.5L not a 1.6 that was original. I\'m trying to figure out what year it was made to get replacement parts.  It is over heating and I went to replace the thermostat and there wasn\'t one installed.The parts guy says they don\'t have a thermostat but that doesn\'t make sense to me. Anybody have any ideas? Thanks.

5A engine - I take it as a 1.5L carb or fuel injection?? They came both ways. For USDM Corollas (1990 Corolla is part of the 6th generation model) - they came with 4AF or 4AFE engines.  This means that you can use most A-series engines as a possible swap candidate.  

The 5A-F was produced in 1987 and the 5A-FE (fuel injected) introduced the same year and ran with the 7th generation Corollas 1995 to 1998 (overseas models only).

It does have a thermostat - should be on the inlet side, right under the distributor.  If it is missing - that would be the source of the overheating issue or was removed intentionaly due to some other problem (removing the thermostat causes the cooling system to become inefficient).

A good autoparts store should have them - just because it is a JDM engine, doesn\'t mean it is impossible to find parts for it here in the States.  The engine has been around long enough for aftermarket repo pieces to be available .  Otherwise - it would be a trip to the dealer.  Toyota uses a weird design of a thermostat - might be on the hard side to find.  Online is hit or miss - but sometimes the only recourse if the dealer doesn\'t stock it or is able to order them.

Good luck
