New high flow thermostats.

Hi guys, I noticed this today at Supercheap - Tridon have released new high flow thermostats. They have a larger thermostat seat that appears to be 30% bigger than the standard. If your engine is running a 54mm thermostat the part number is TT2040-180 but they come at a price...$25ish. If you want to improve your coolant flow, take some load off your water pump and possibly reduce fuel consumption in the process, here's the ticket. 8-)

Thanks for the tip! I'm not sure if my Sirius one is the same but will check it out. A while back I had heating issues and I took the stat out but that was too cold so ended up putting one in but a lower temp. High flow might solve my issue!

Yup. I've used high flow 'stats in my JEEP now for a while. Provides a more stable temp...

cheers

I've been using it in my Astron II 2.6 and the temperature is a lot more stable and runs cooler too.

Just a little advice. If you buy one of these Tridon hi flo thermostats, keep your receipt, and keep an eye on your temperature gauge. Put one in about 3 months ago. Checked the gauge every now and then , and everything was fine. Drove to the exhaust shop a couple of days ago. The owner put it up on the hoist and then said... you know you have a coolant leak up the front somewhere. I didnt think much about it on the drive home. Pulled up in the driveway...went inside...came back out and there was coolant running across the drive. Lifted the bonnet, and seriously the top radiator hose looked like it was about to explode...literally. It was under SOOOOO much pressure that the coolant was being forced out where the hose meets the radiator. Bottom hose was basicly cold. Obviously a classic thermostat failure. The thermostat was still in one piece and looked fine to the naked eye. I stuck it in some water in a saucepan on the stove and it did not open until the water was boiling it's ass off. So lucky not to crack the head.

That was a close call Sigmaproject, but it would be hard to say whether that was caused by a faulty designed thermostat or one of those random manufacturers' defective units. It was unusual that your radiator cap didn't bypass the excessive build up of pressure. Still, its good advice to hold onto your receipts in case something like this happens.

Obviously I just got a dud. The first thermostat failure in a million kilometres of driving. ( I figure I have done a million, I put half a million on my WB 1 tonner work truck alone)
It was so ironic that this happened when it did. The Sigma was up on the hoist waiting for the exhaust to cool a little, and I was talking to the exhaust shop guy about radiators. He has a Falcon turbo, and has just fitted his second recored radiator.
Naturally I told him that I had my recore done 10 years ago, and that I had never had cooling issues. He was only too pleased to point out the obvious coolant leak :$

Any idea if these thermostats are available in different temp ranges?

its a bit of a trick this high flow thermostat - yes it may flow more if your engine is way to hot but if your cooling system is working right the flow will be the same even with a bigger valve and seat

the bimetal spring that controls the thermostat will just close the hole down to keep a constant temp
so thats the same load on the water pump , the same fuel consumption and in fact should hold the temp and a std sized thermostat

as a std size therostat flows more than enough to hold your temp inside the range intended if it doesn't its faulty on the cooling system is not up to scratch

in fact a higher flow may heat the rear of the block more ( and even running to hot ) than the front as the water can flow quicker through the easiest path
