Heater hose delete

[SIX_SEVEN_ONE]

Wassup eryone,

Quick ?? Can I just block off the ports that used to got to the heater core?

I was gonna connect the 2 but its gonna be a pain being so close the the fuel rail. I dont want hot coolant lines leaning on the banjo fitting.

Thanks in advance!!:biglaugh:

That is a good question that I have wondered myself a few times since I never use the heat or the ac.

Id think you need to connect the two, thats part of the circulation. if you just block them off your cutting out circulation..

Ya if you block them off the back of the engine does not get flow.

Thats what I thought.

Thanks!!

Doesn't the heater valve close, with the AC on max?

 

[SIX_SEVEN_ONE]

Thats a good point.

Guys???

Forgot about the other line at the back of the head.

Still tho with 7m head gasket issues and the usuall 5-6 always blown best to loop the lines and let the coolant flow as much as possible.

I will be deleting mine (1JZ)

Figure it has been fine for years with the heater valve always closed when at trackdays.
Shouldn't be any different if it's capped off.

Will also be ditching the block mounted water/oil cooler and going with a inline thermostat & big air/oil cooler.
Thus removing the whole metal tube around the back of the block.

ps. If you look at the 1JZ/2JZ coolant flow diagrams in the TRSM, the primary coolant circulation is through the block to the head (back to front) and out to the raditor.
If anything, removing the heater circuit will be promoting more coolant flow through the head.

Loop the lines for sure, keep it moving... Especially back there were heat builds up
