cooling does your jaguar overheat we can help flex-fans have long been used in racing and recreational vehicles where maximum cooling is essential we offer flex-fan conversion kits engineered just for jaguars after using the flex-fan kits ourselves and providing them to many satisfied customers we thoroughly recommend them simple flex-fans come ready to install no electrical connections or switches quick installation reliable no moving parts eliminates fan clutch quality flex-fans are made in the u.s and include a precise adaptor fans are dynamically balanced flex fans at low rpm the curvature of the fan blades ensures lots of air is pulled through the radiator this keeps your engine from overheating in traffic and provides maximum air flow when it s needed most as engine speed increases the blades flatten hence the flex name reducing air flow as ram air takes over to cool the engine because the fan is now drawing less air it has less aerodynamic drag greatly reducing the engine power required to drive the fan and increasing performance and mileage xk-120 early 5 bolt cast 5-blade oem fan 17-0774 xk-120 late 4 bolt rivited 6-blade oem fan 17-0775 xk-140 xk-150 17-0776 mk i mk ii 3.4s 3.8s 17-0776-2 flex-fan operating principle red line waterwettertm most older jaguar cooling systems are barely adequate for american driving red line supercool with waterwetter can make a big difference by doubling the wetting ability of water and therefore its ability to transfer heat away from your engine it also provides superior corrosion protection compared to conventional glycol-based antifreeze/coolant one 12-ounce bottle treats 12-16 quarts of water or a 50 percent ethylene or propylene glycol solution for best corrosion protection replenish or replace every 15,000 miles we use red line supercool in our race cars and highly recommend it 17-0055 the correct thermostat for many 3.4 and 3.8 jaguars many jaguars from 1949 to 1967 with 3.4 or 3.8 liter engines use what s called a by-pass thermostat they use a sleeve that closes the by-pass port when the thermostat opens this ensures all water passes through the radiator and is therefore cooled without a bypass thermostat about 20 percent of the coolant never passes through the radiator this should help your jaguar run cooler 09-0160 superstat jubilee stainless steel hose clamps these clamps are the closest substitute for cheney and other original clamps they have a hex hed cheneys had round heads but per original style the kerfs are not cut through the band of the clamp made in the u.k jubilee clamps are stainless-steel and of excellent quality cooling system size part number 3/8 1/2 09-bs/12 1/2 5/8 09-bs/16 1/2 3/4 09-bs/20 5/8 7/8 09-bs/22 3/4 1 09-bs/25 7/8 1-1/8 09-bs/30 1 1-3/8 09-bs/35 1-1/8 1-5/8 09-bs/40 1-1/4 1-7/8 09-bs/50 1-1/2 2-1/8 09-bs/55 210 xks unlimited · 850 fiero lane san luis obispo ca · 805 544-7864 · 800 444-5247 jags · fax 805 544-1664 © xks unlimited 2005
