Thermostats bearing the High Flow logo are Tridon High Flow thermostats. Tridon’s range of High Flow thermostats are designed to improve cooling system performance. The High Flow thermostat has a larger valve allowing up to 50% more coolant flow, eliminating the need to use a cooler temperature thermostat.
My car was overheating for a while and I replaced the thermostat several times but with the standard one from our local store. They stocked the standard thermostat but not the high flow. Since installing the high flow I have had no further issues and have very good flow through my engine as it now runs at a constant temp with no issues. I am very happy with this product and am certain it will not let me down. Highly recommended for the 350 chev engine with a few modifications...….
Great part does what is meant to do and started off at a good price even including the post however by the time customs UK had added another £17 it started to hurt the pocket .
I wish they had a nearer dealer as they are very helpful and its is a good little part that arrived surprisingly quickly .
