Puffwagon Trust me bro... Gold Donating Members 16,049 Member For: 9y 11m 14d Gender: Male Location: South Australia Posted 05/10/16 01:05 PM Share Posted 05/10/16 01:05 PM Sounds like the thermostat was sticking initially and once replaced acted like a thermostat should. @ROB83R 70 to 90 is just fine for an alloy/cast motor. Don't go colder, you'll run into several issues, while not major, will decrease engine life and increase fuel consumption. On that note don't flog ya car until it's warmed up!

Fans need to be adjusted to turn on at the correct temp 2 Link to comment Share on other sites More sharing options...

One thing I picked up over the years is don't trust a factory sender for diagnosis especially temp senders and oil switches. A motor can be too hot by the time it goes up and there could be not enough oil well before the light comes on. Link to comment Share on other sites More sharing options...

Have been thinking about going back to a stock one due to reading about fuel consumption etc. Should I return to a stock thermostat? Link to comment Share on other sites More sharing options...

Fuel consumption is tune related not temp related, but the tune is temp related so it affects the fuel consumption if that makes sense. All things being right nothing drastic would change by heating your engine up a few degrees. Link to comment Share on other sites More sharing options...

Edit: Agree on fan tuning though Edited 05/10/16 01:45 PM by Puffwagon Link to comment Share on other sites More sharing options...
