Draining coolant

[Joshua993]

I will thank all of you in advance for tolerating yet another new cruiser owner question.

The FSM states to drain the engine coolant for just about everything - is that really necessary? I am getting ready to pull my throttle body for cleaning and just got to reading the FSM about it. I dont see any lines running to the throttle body that would require me to drain the coolant to do this...

thanks

Or...not. I am guessing that nobody else knows - or nobody does what the FSM calls for in this case?

Just pull them, you might get a little fluid coming out, but so what.

I pulled the throttle body for cleaning last weekend. I just pulled the hoses off and plugged them with an appropriately sized bolt. Worked real well and lost very little fluid.

I let the throttle body sit in some Purple Power degreaser and it cleaned up real nicely. Don't forget to blow some air through the two micro vacuum ports (mine were crudded up). The cleanup and TPS replacement fixed my fast idle problem.

Good luck.

Purple power, eh? I will have to give that a go. I will have to look under the hood again and see these lines that needed plugged. I haven't spent a lot of time under there yet - just got the truck mid April. Last wheeler was a Jeep Cherokee XJ - it needed very little maintenence - I have to block out time on my weekends for this cruiser!

Thanks for the replies.

Get the cruiser hot then drain about 1 or 2 inches just enough to lower the level. Why i say get it hot is because the thermostat needs to open first.




BUT if it was me i would say skip that and just plug the lines off.....very little to none antifreeze come out
