help with some hoses

[deutschman]

Hey I am not sure where these go. I looked in my manual but could not find any definitive answer. Where do they run?
These guys are on the left side of the throttle body (when looking from intake side of engine) I know they have something to do with coolant...

Then there are these two on the bottom of the water pump.

Any help?

Cheers!

Do the outlets in the top picture go to the charcoal canister? Do I need to run a charcoal canister on my m20 or can I find a way around it?

Im sure you can find the charcoal canister delete mod but I suggest you retain it. Its there for a reason.

The throttle has coolant lines running into that fitting. I suggest you check realoem.com to see the diagram and it will help you visually reassemble the coolant lines there.

Cap the two ports on the throttle body just to keep things clean.It's a heater circuit to stop the TB from getting frosty(jams the butterfly).
My M20 ran without issues on the evap/charcoal canister delete. ymmv.
I'll have to look at the car to see what's up in pic 2.

Edit:
pic #2(probably the feed to one of the cooling ports in pic #1. You'll have to cap four hose flanges if you're deleting the TB warming circuit.)

I went to real oem and did that. How ever it only shows those hoses connected to the throttle body, but does not show to where they run.

One of my friends is going to take pictures of his m20 and let me see where these hoses run to. Thanks guys.

Little late to this but......



left port (small) goes to the throttle body.



Right port hose runs along the block and attaches to a 'T' near the firewall.

Interesting. On mine, the right port ran to the block...

Also OP, in the first post, that is not your waterpump. That is the thermostat housing.

Thanks guys!

Good lord Ski! Those hoses on your tstat are getting ready to let go any minute now...
