Has anybody tried using vacuum for the coolant replacement

[slicky rick]

Iv done coolant changes on several other cars... Doing the search for coolant replacement, most seem to be refilling and running the car making it cool down adding coolant etc etc... Will anything be damaged if vacuum filling is done? It so much easier!

It's not that much easier. The 200's coolant self-bleeds so it's just a matter of pouring in coolant. If it were a SBC, I'd say vacuum filling is quicker but the 3UR is dummy proof when it comes to coolant refilling.

Hey tony... Not yet versed with the acronyms yet. My lc is the Ttd.sbc? 3ur i suppose your referring to the gas engine?

 

[Mixelplix]

SBC is an acronym for small block chevy; and the 3ur is the engine code for the 5.7l gas 200 series engine

With the extra heater core and other places for air in these systems I’d definitely use a vacuum filler if I had access to one.

So it would seem that there won't be any problems with vacuum filling with our rigs and that nothing will be damaged...
