2002 Volvo S40 Turbo, coolant line to intake

[S40Luckey]

Hi All,

I have the engine and transmission out of the car for a transmission swap, and want to know if I can delete the intake-manifold coolant heater lines by capping it at the thermostat and engine block? I'm thinking it will be fine, but wanted to see if anyone could verify. I figure that removing the extra failure points is a good thing, and it cleans up under the hood. The car's a little cold-blooded with that coolant line already looped, but nothing unbearable.

Underhood Mods for the car:
-Upsolute tune
-14t turbo
-upgraded exhaust (turbo-back)
-Stock Volvo PCV system deleted. I replaced it with a sensible catch-can setup
-Looped the coolant lines to the intake manifold
-working on bottom-mount intercooler. Should be done next month

Yes. The coolant to the intake manifold is only useful in cold areas or cold weather situations. It's bypassed on mine

Thanks! Just finished putting everything back together. I hope to get it all sorted out and to the dyno for base tuning in a month or so.
