g13 coolant issues anyone?

[Tubbs76]

Recently did a flush and thought I'd try g13. Have been running a week odd and must say the result has been very disappointing to say the least. Coolant temp on average is higher, can't run my air con with coolant teno soaring too 100c and have also noticed my oil temp is now averaging 100c as opposed to 94-96c. Has anyone else has any issues with this coolant? I'm ready to dump and go back to my old brand...

What about other things like pressure cap, thermostat, and radiator condition? Have you tested the fans?

100deg Celcius for coolant temp isn't boiling when it's pressurised.

Bare in mind, the weather has been getting pretty hot these last few days.

You're doing well with an average oil temp of 94-96... I sit at 100-105 up here in brissy.

Whole cooling system is virtually brand new. New t stat, t stat housing, flanges, crack pipe in last 6 months. All new silicone hoses in last 3 months and a new aluminum radiatorca week ago. Expansuon tank and cap also new. Has been bleed properly etc..has only started running high since the g13 put in. Even when driving, coolant temp pretty much on average between 88c -90c. Normally only hits 90c if sitting in traffic. Otherwise normally 80c -82c when driving consistently. I've never had my coolant temp hit 100c with air con on even in a hot day. Oil temp also noticeably higher. Fans all work properly and cone on at 90c.me thinks me going back to valvoline zerex g05. As it stands, out performs g13 by a mile. I was speaking with kay offline and he also mentioned he was using a castrol coolant and swapped to g13 recently and he also noticed higher temps and he is also going back to his normal coolant of choice..maybe g13 and vr6 don't mix?

[Tubbs76]

Yeah. Even on a hot day driving on motorway, I haven't hit past 104c. Now I'm sitting on a 100c just putting around...

Has anyone else had any similar experiences with G13?

I run g13 but admittedly get the higher oil temps you're talking about. Although I sit at about 90C with coolant temp.

interesting. starting to think that that G13 dont like VR6's lol.. as mentioned, def have noticed higher temps since using it. come weekend, im going to be dumping it, complete flush again and going back to valvoline zerex g05. I guess it is just suited more to the newer VW's. unfortunate as im all or the environmental factor, less emmissions, etc... but aint killin my ride over it...

The VR6's run pretty damn warm, even with the G12/G12+ I was running over 100c on oil most of the time and well above that if you pushed it hard. I seriously considered getting an oil cooler, but then it was really only an issue when it was on the track

Even though oil would go up I never saw the coolant needle go anywhere but straight up, pointing at 90. Other than the fact it built up to that point while warming up I'd almost say it didn't work! It was always completely stable.

How do you find it with the air con on? when air con on, coolant tem siting at 100c. that crazy.. does yours do the same or does it saty at 90c
