Two words: De Frost. In Florida you will want it, it is amazing how quickly your windows fog up down here with the humidity. Just food for thought.

If you have EFI then you will need a place for the ECT...

You'll need a small plug for the back of the intake where the TB spacer coolant line used to go (1/4" NPT, IIRC) and a brass bushing to plug your ECT sensor into the front of the intake where your heater pipe used to go in - not sure of the diameter (sorry, I'm senile), but go raid the Dorman drawers of your local Autozone and you'll find it in there. Also, you'll need a hose nipple cap for the extra water pump outlet that you won't be using; you can either use a formed rubber cap (also at Autozone, in the coolant-related goodies aisle) or just take a short bit of heater hose with a big fat bolt slathered with RTV silicone sealant shoved and clamped into the end of it ... and be sure to use good stainless steel hose clamps to secure everything.

DO NOT try to use a little vacuum cap to plug that back nipple on the rear of the intake, even with a little hose clamp. That thing can see way more pressure than a vacuum cap can contain, and I found out the hard way when I went WOT one time and that sucker popped, spewing coolant allllllll over underhood. ("So much blood for such a tiny little hole..." )

Engine Coolent Temperture sensor.
This is how the ECC knows when the engine is cold or hot.

This is exactly what I did when I put the ECT back in after the previous owner removed it and the heater hardlines.

If you keep the heater, remove the hard lines and use heater hose, its a lot easier to service the engine. I cut the part with that sensor thing off and kept that, then ran the rest with rubber hose.

I hate to hijack the thread but...

I have a carb'd engine and plan on removing the heater rail. Are you saying to plug the outlet off the water pump all you have to do is put a nipple cap with a clamp over it and that is good enough to hold the pressure? Thanks
