was told by a Toyota Service that this would only be 1 hour more labor and cost me about 140 dollars more..and that they always recommend it being done same time as timing belt and water pump replacement....but is really a good idea or not? (if engine is 20 years old..but has ony 150 ,000 miles on it..btw. this is for a 94 Toyota 4 Runner V6 engine
Yes do it. As long as your in there. I do the same thing and recommend it also. You have a good mechanic man that seems to know their stuff.
Do not use that shop again. There's more work than that involved in doing what they say they can do in an hour. I have never had those recommendations for any of my Toyotas that were serviced regularly.
The genuine AISIN timing belt water Pump kit is about $140 at ROCK AUTO! It is NOT necessary to replace the VALVE SEALS! This usually requires removing the YIELDING HEAD to do this! The OI OIL PUMP SEAL would be LEAKING BADLY by now, and it is BEST not to disturb it, if it was NOT LEAKING! Many times they DAMAGE the SEAL housing and cause MORE trouble than it is WORTH! Use the RIGHT type of SYNTHETIC OIL at oil change time with the TOYOTA approval spec numbers printed on the LABEL! I would clean your THROTTLE BODY and IDLE AIR CONTROL valve instead! UUSUALLY, they want you to replace the CAM seals and NOT the oil pump seals WEIRD! IN detorit the 3.0 engien TIMIGN BELT and WATER PUM Preaplcements cost about $750 at either LEXUS or TOYOTA dealership! WOW! I wodu lNOT disturb the seals if they are NOT LEAKING by now! This is NOT a cavlier or PINTO here! The PRECISON with wich a TOYOTA engein is amde and the MATERIALS they have tested and PROVEN to be GREAT should NOT leak in ANOTHER 150k miles! Get a MOTOR FLUSH and retin the ORIGNAL seals! GOOD LUCK!!
