1. 18 Slide timing belt on Install first on cam sprockets Use c clamps to hold belt onto sprockets Install last onto one of the smooth idler pulleys slid it last onto the idler pulley to the left of the crank sprocket 19 Make sure timing belt is lined up correctly 20 Remove allen bolt from tensioner 21 Put plastic covers on Make sure that the covers properly seal up the timing belt area Water or oil leaks into the timing belt area could cause problems If the seals were exposed to oil chances are that they swelled and may not align properly Take the time to make them fit properly 22 Put the rest of the stuff back on This would be a good time to inspect the radiator and flush out both the interior and exterior Flush interior with water use whatever is needed to clean exterior area 23 Fill radiator See options below Drive harmonic damper removal options A best option Puts the least amount of stress on the crank shaft Put a little Liquid Wrench or PB Plaster between the bolt and the damper and let it sit for a few minutes or hours Then put breaker bar securely on bolt and orient breaker bar so that it points straight up Using a 2 Ib hammer whack the bar from right to left just like an impact wrench It may take a few tries but the bolt will eventually spin loose B AT cars block the engine from moving by placing a flathead screwdriver in the torque converter teeth and use a breaker bar C MT cars2.

5. r pump seal wear Avoid 2 EHA Organic Acid Technology OAT based antifreeze These types of antifreeze are commonly called Dex Cool compatible antifreeze The 2 EHA anti corrosion agent has been shown to soften seals which will contribute to water pump seal failure and leaks in other sealing gaskets e g head gasket The newer sebacate acid based OAT antifreezes do not have this problem OAT anti corrosion agents are not fast acting and thus it is necessary to add some sort of fast acting protection for the water pump impeller and other places where bubbles may form and collapse Toyota Honda and Subaru all now use a long life antifreeze with sebacate acid OAT and phosphate based anti corrosion agents So your best bet for antifreeze is to use Subaru brand or Toyota brand antifreeze have heard that both antifreezes have the same composition Some newer Subaru service manuals recommend adding a bottle of Subaru Cooling System Conditioner This stuff was designed to fix leaky head gasket problems with certain post 1998 Subaru motors This stuff fixes leaks by filling in holes in the leaky gasket have heard from one major Subaru dealer that this stuff is also causing clogging radiators So its best not to use this stuff on an SVX When filling the radiator use deionized demineralized water The ionic minerals in tap water contribute to the corrosion process Flush the cooling system with deionized water several time prior to filling it
6. ry is to get a piece of steel with long bolts going through that fit into the space in the cam sprocket 3 Before you take the timing belt off put a 17mm wrench on one pulley bolt and put your big cheater type 17mm socket on the other pulley bolt and rotate things until the wrench on one pulley is jammed against something solid I used a cheater against the floor Then break loose the first bolt Reverse the procedure for the other bolt This will retighten the one you just broke loose but it won t be nearly as tight Go back to the bolt you just retightened and put the wrench on it and smack the wrench with a soft hammer Viola Both bolts broken loose and no damage to the cam pulleys Boundsie s method KKKK KKK oil pump replacement tips 1 oil pump replacement is optional per Beav and red95svx 2 use hylomar for sealing the pump against the engine case per Beav KKK KKKK filling the radiator KKKK Maximum cooling performance is achieved by using Redline Water Wetter and the minimum amount of antifreeze needed to keep the coolant from freezing in your climate Water Wetter improves the heat transfer into water and it also contains anti corrosion agents It contains on silicates or phosphates Use an antifreeze that is silicate free Phosphates are a good anti corrosion agent for aluminum but the anti corrosion layer supposedly inhibits heat transfer to the water Silicates are thought by the Japanese to accelerate wate
