i just finished swapping out my engine and the heater isnt working well. i feel a little heat while driving, but idle, i feel none. At first i thought, "ive seen this before on my last engine change, coolant is low." so I looked and sure enough, it was a little low because it had circulated through the engine some from driving/running. I topped it off and the problem persisted, but i only drove it a short distance. I checked again this morning and its still full (radiator).

Am i missing something else?

My new mods during the engine swap were a new mishimoto radiator and mishimoto thermostat. The car seems runs much cooler temps judging from the thermostat gauge, but i wouldnt think that would make the heater not work.

 

Air.

 

air in the system? alright, how do i get it out? let it run with that top vent open in the hose that i *think* goes into the heater by the battery?

 

Scroll down to "bleeding the system"

and using a Lisle funnel makes the job a million times easier.

Thanks for sharing these two links.

 

yeah thanks. ill try that. maybe my drive to work today got some of the air out

 

You can also used the bleeder valve at the back, not nearly as effective.
