read fsm, searched a few old posts....how do you guys really change the tcs fluid out? it looks like i should open the suction hose near the pump, but how to get the rest? run the pump off of hotwired battery power to circulate it?

look at the hose, opinions on if it is leaking and needs replace?



also, it looks like the physical separation between the tcs/abs systems is at the plunger valves of the tcs actuator. will someone please confirm that the systems are firewalled, and therefore it makes no difference which order i do fluid in? tcs first or brakes first? or does it?

Is that picture in the passenger side wheel well?

On my TCS pump there were 3 little bleeders... Id suck out the Fluid from the res. and bleed the TCS pump.....

I looked in the FSM, and it says that you just disconnect the hose that goes between the pump and the actuator.. on the pump side.

Then just air bleed after you replace the fluid...I know theres one bleeder for there somewhere....
