Have they though? I think even my 89 CRX Si had a dumbed down one. Four BMW's, a Miata, three Audis and a couple of GTI's, not one of them had a truly analog coolant gauge. Fact is that oil temps drive up coolant temp, so if you can monitor oil temps, you'll be better off. One of the reasons I'd prefer to do a proper oil cooler before tackling a larger radiator. Keep the oil cool and your coolant won't be an issue.
Just thinking this through, but isn't it going to be roughly the same until the thermostat is unable to keep up? Then once the oil temp has been high enough and thermal transfer is higher than the thermostat can keep up with, things will all go horribly wrong? Just thinking that there's really no such thing as "a little warm" just okay and not okay. Clearly a larger, more efficient radiator will add thermal capacity, but I'm still thinking that an external oil cooler will have a larger, more noticeable impact. Dont' R's have an oil cooler stock? Guess I need to look at their parts diagram and see if I can just route one of those.
Racecars use it because racecars typically only run water as the coolant through the radiator. Coolant/antifreeze on the track is a no-no because it's slippery as shit and impossible to remove. Your daily-driven vw doesn't need that.
under the performance monitor on radio... you can customize 3 gauges (at least my 17). Mine mirrors the readout on the main dash.
Swipe up or down on any of the three gauges until it cycles to the coolant gauge.
Thanks for this, hadn't really messed with the settings in this and didn't realize it was so flexible. Nice to have oil and coolant temp shown together. Seems to confirm that as long as the thermostat can keep up, coolant temps is nearly steady, but oil temp responds pretty directly to driving manner.
Interesting!I have followed a few builds and read about different approaches to cure the
the achilles heel of the MK7... cooling. But the solutions are all over the place
and since the car has so many cooling problems, maybe it's time to start a thread just about that.
And if there is one already then laugh hard now and show me where it is!
If not then who here thinks they have cooling this vacuum cleaner of a motor
as much as possible for daily driving with some aggressive every now and then and an occasional track
day? All cars vary so I would like to hear where you started, where you ended up,
and which components you replaced. It would also be great to hear tips you
learned along the way.
