3/2003-12/2006 HOLDEN VECTRA ZC 4CYL 2.2L Z22SE. TRIDON PRODUCT. Tridon’s range of high flow thermostats are designed to improve cooling system performance. The thermostat must be compatible with the vehicle cooling system; the Tridon thermostat range has been carefully researched and engineered to suit each specific application.
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 .
