Hi, everyone!

Just wandering how can you tell the diference of the engine of S70 2.0T & T5 by just look at it? Thanks!

 

There is no 2.0 liter engine in the U.S. It's either 2.4 liter which is the normally aspirated and low pressure turbo engine (GLT engine) or the 2.3 liter T5 engine. It's pretty easy to identify the NA engine as there is no turbo discharge piping that goes over the top of the engine, the outlet of the air filter housing goes right into the throttle body.

 

I understand there are a few different engine for S70 and the N/A engine and turbo should be easy to tell the difference as simul8guy mention. But how can i tell a S70 T5 is a S70 T5 not the low pressure turbo one?

 

For 98 you can look at the vin. It has 53 in the 6th and 7th positons if it is a T5, and 56 if it is a low pressure turbo.I know this was true for 98, and I think it went all the way through 2001, but I'm not positive. On the 850's it was 58 for the R, 57 for the T5 or Turbo, and56 for the GLT which was a low pressure turbo for 97 only.

 

The T5 has an intercooler attached to the radiator. The LPT engine is not intercooled. So the T5 turbo discharge piping goes to the intercooler while the LPT piping goes to the throttle body inlet. As JimKW noted a T5 has '53' as the 6th and 7th digits in the VIN (example: YV1LS53........) whereas an LPT is '56' and a normally aspirated car is '55' (although the normally aspirated SE model is '61').

 

Um I do think your wrong in saying the LPT doesn't have an intercooler. I'm pretty sure it does. Also I have a 1999 s70 awd, which is an LPT and it has an intercooler.

So your wrong in saying the LPT isn't intercooled, because it is.

 

All Volvo turbo cars since around mid 1980's have intercoolers.
The Vin# is the best way to tell which engine it has.

 

I'm just going by the spec sheet for the 98 GLT and T5. The GLT engine is described as '2.4L with exhaust driven turbocharger'. The T5 engine is described as '2.3L high pressure turbocharged with intercooler'. If TECH says that the LPT engine is also intercooled then I believe him. I've only owned T5s......
