Mr Polson 10,214 Posted September 26, 2020 Just out of curiosity what does this PVS actually do, or is it just part of the choke setup.It's to with AC I believe, because non AC carby cars didn't have it, and EFI didn't have it (because computer controlled all the stuff Dave mentioned) 1 roKWiz reacted to this Share this post Link to post Share on other sites

FORD_MAN 1,026 Posted September 27, 2020 When I finally replaced my XF utes heater tap as it had a leak & didn't work found it was blocked solid, changed to new one & heater finally worked, till it split the heater core about 18mths later (which I still need to replace ), block off for thermostat housing is 3/8" (GAS), likes of supercheap have them in a blister pack on the stand with the trim clips & bolts packs. or if want to fit thermo fans later a Tridon TFS110 thermo fan switch will fit, 1 roKWiz reacted to this Share this post Link to post Share on other sites
