SPA Temp Gauge reads low

I would be interested seeing as it looks like I can't fix it myself with a hacksaw and tapping the thread in the tube a bit deeper. Anyway, it would probably leak and need lashings of PTFE tape!

Presumably ACT will sell the pipe individually, rather than as the set of both pipes they currently have on their website?

That is my understanding after a chat with Tim.

A quick edit to add that talking to Tim at ACT he will offer the pipes individually and will indeed stock them for future upgrades.

He is waiting to hear back from the factory about when they can supply them.

Just had a message from ACT saying that the correct pipes to make the SPA gauge read correctly are in stock so if you have an SPA Gauge and want it to read correctly give ACT a call.

Mine is in the post now.

I saw Tim's email, I will be calling them today.

Funnily enough I was fixing my Spa gauge over the weekend, the oil pressure sender wire fell onto the exhaust . A bit of splicing, soldering and heat shrink, job done!

This should be better! New ACT pipe fitted. The original sensor was recessed by about a centimetre and the recess was full of gunk.

On first start up to bleed the system, the gauge went up quicker. Will check against the ECU when I get a chance.

Does anyone who has now bought this new design want to sell their original capillary type ACT pipe?

clearly wasn't purged, look at how rough it is where the weld has penetrated

Yes, planning on swapping mine over next weekend.

Drop me a mail.

Yes but it works :-)

Bit of a thread resurrection. I too have a SPA gauge which reads about 10 deg low, mine is also installed in the ACT stainless steel water pipes which is considerably out of the water flow. I've just moved the sensor and installed it in to one of the water rails bleeds screws.

I haven't tried it yet but I'm hopeful it will now be more representative of the actual water temperature as the probe is directly in the water flow, albeit only now on one bank of the engine. Once I've finished the other 100 little jobs I'm doing to the car I'll start it up and report back on the findings.

Hello Adam, did this work out well for you in the end?

Hi Duncan,
Yes it did, you just need to make sure the boss that is used allows the sensor to sit low enough that it contacts the water in the rail. It also needed a bit of bleeding to get the air out.
It’s a slightly compromised solution compared to locating next to the ÉCU sensor but the reading is much more accurate.

Thanks for the reply Adam, and I'm glad this has worked for you
