Thoughts? Too Low !! Try to get a 85c unit for QLD. I have been using a 88c here in Canberra for many years... Very happy with it. Link to comment Share on other sites More sharing options...

Wondering if the coolant change just trigged a dodgy thermostat that now doesn't close 100%. Will look at a new one. Hopefully get quicker warm up temp too Link to comment Share on other sites More sharing options...
Spoony Member 250 Member For: 13y 6m 8d Gender: Male Location: Brisbane Posted 22/06/13 01:22 AM Share Posted 22/06/13 01:22 AM (edited) Turns out the original thermostat wasn't closing up fully under its own spring. Interestingly it also had an additional hole as some others have found.The rubber seal was pretty distorted with some calcium build up, its only 07 but perhaps 200,000kms it's excusable?Went with an 82 hiflow. Hopefully quicker warm up and cooler loaded temps Edited 22/06/13 01:23 AM by Spoony 1 Link to comment Share on other sites More sharing options...

Spoony Member 250 Member For: 13y 6m 8d Gender: Male Location: Brisbane Posted 23/06/13 09:56 PM Share Posted 23/06/13 09:56 PM I did actually wonder about this and fuel usage too. 92 is the 'stock' after market replacement option, there was only an 82 at Supercheap when I was there but perhaps 88 or whatever is a better option. hmmmmmm.

You want good economy when cruising so I would think standard is better. Bumper to bumper the coolant temp is same as standard and when boosting hard it is same as standard. Sounds pointless without a thermo fan setting change. Almost pointless all together. In saying that I am no tuner, and I don't see the difference on a lap top. Thoughts?
