I would leave the TPS unless it's causing an issue.

As far as adding, maybe:

• Coolant overflow tank cap
• Battery terminals if corroded at all

JDM owners need to be concerned about the oil hoses for their cooling fans and the cap seal on the res.

Strut rod bushings should also be on the list.

Yoda,
Do you have the part numbers for the vacuum hoses you mentioned? Mine is a '99LS, would like to have all parts ready before I change the starter.

Another one here asking for the vacuum hose part numbers please. I've got a 1998 LS so it should be all the same

Refer to exploded parts diagrams and contact Lexus....they will.assist you. Have VIN # ready

I still have the original VC gasket and tube seals and only now they're starting to become an issue with some slight oil drips occasionally at 287k.

It really depends on the shape of the car and how much $ are you willing to spend. I replace leaky gaskets if they are easy to get to or if other PM needs to be done. If you're changing the spark plugs, you might as well go in and replace the valve cover gaskets, spark plug tube seals and grommets. If you're doing a timing belt change, you're replacing the water pump gasket and the thermostat housing O-rings while you're in there. Don't touch the TPS unless you need to - like the CEL turning on and there's a code related to that.

As for the soft parts on the suspension, do those when you're replacing the shocks or if you hear clunking sounds over bumps. Doesn't hurt to install new OEM engine/trans mounts. I wouldn't touch the bulbs unless you need to replace a burned out one. The OEM Toshiba or Koito bulbs in these cars do live a long life but all bulbs do burn out or break.

YODAONE

Burnt out bulbs = probable cause for stop by law enforcement...

nthach

That's true - but I don't usually replace bulbs out of prophylaxis unless they are HID xenon bulbs or headlights. Then it makes sense to replace in pairs.

AM literally replacing my bulbs with propylaxis:

Vepagoo Lexus LS400 1998-2000 Gas Charged Hood Lift Support Shock Strut (Set of 2) $18.99

Consider hood shocks as well . My hood slammed shut while lowering my car with a floor jack. Yikes!
These work really well. We will see how long they (currently unavailable on Amazon now) hold up. The old set lasted 4 years.
