Block Tester

The FROST catalogue arrived this morning, they sell a product called Block Tester - similar idea to the Magic Coolant in the post by Haydn. It's a test kit for £40 that uses a reagent that turns from blue to yellow if exhaust gases are present in the header tank.

Have a look

They also sell the fluid separately for £7.50. Reckon that a cheap syringe could be used instead of the kit? Might be an option if a sniffer test isn't an option?

It does seem rather expensive for the kit :shock: I agree that a syringe should work.

I'm wondering if the reagent fluid is the same as the Toyota coolant that Haydn spotted - might be an even cheaper option.

Hi guys these kits are for testing for exhaust gases present in the coolant by means of filling the sniffer with a small amount of fluid and the placing in the neck of the header tank and squeezing the black bulb bit quite a few times (pumping action)thus drawing the vapor from the header tank through a 1 way valve, the bubbling action created in the sniffer chamber(the clear bit) and after 30secs+ upto a minute if the blue liquid detects Exhaust gases(carbon monoxide) then it changes to what looks like urine :wink:

The sniffer kit or fluid should not come into contact with the coolant or you have to empty the fluid and clean down the sniffer unit..and start again...

But a good bit of kit though =D>

Ah - so this is the 'sniffer' test kit then.

I'll put the turkey baster back then!

I was chatting to a guy from one of the garages that Wheelquick deal with and he said they use that (or similar) to test for exhaust gas. Said it works fine.

I have a system which detects combustion gas (CO2)in the steam, but it can't be used IN the coolant. A MOT tester could use the 4 gas analyser for testing for carbon dioxide in the steam

I thought that Dandy's system was the official one, useful to know the block tester kits are out there.
