Moss Coolant Reroute Spacer No Longer Available?
 

I'm looking for a cheap way to do the coolant reroute. I went to the Moss website and typed in 051-046, and got the response:

"Part number was not found"

Does anyone know if it is still available? I haven't called them yet.

Anyone know of any other cheap spacer options, that don't require a mill and/or lathe at your disposal?

Don't know if this helps but a guy over here in the UK is having some made.

I just bought one. You have to call them, they are not available online for some reason. You will need a lathe to turn the recess for the thermostat and if you want a bung for the temp sending unit, a tig welder. You will also need to drill & tap it for the other hose fittings.

If you can't do this yourself, you are probably better getting the BEGi. If you have to pay someone to modify the Moss one, you will probably end up spending more.

Lol, what are they then? A 1" hunk of aluminum in the shape of athermostat gasket?

AFAIK, it's never been listed in the online catalog. You have to call them.

I have one in the garage i'll sell for below what a new one costs. It is unused, I think drilling was started for a temp port?

I'd have to check on it. Pretty sure I know where it is.

basically. Well, exactly really, only a bit bigger than the size of the gasket :) I ordered one last year and haven't used it, need to turn the recess for a thermostat and resell it here. At any rate... I know I didn't call them for it, used that form IIRC, they must have changed something.

begi has one too - http://www.bellengineering.net/produ...roducts_id=401

Found this pic. Thought it was funny.

Splitime - let me know if you find the one in your garage, and I'll take it off your hands.

$92 for the BEGI spacer just seems like ALOT of money. The group buy in England works out to about the same amount.

Last night I drilled and tapped a hole in the side of the head for a 5/8" x 3/8 NPT Fitting to feed the Heater core (a la spacerless reroute). This way I won't have to modify the Moss spacer with a step for the Thermostat - I can just put the thermostat in the cylinder head as design intent, then just use the spacer to get around the fittings on the cold side of the engine.

It looks like there is no easy way to do a spacerless reroute to the cold side of the engine - the thermostat housings will only fit pointing towards the hot side of the engine, or straight up into the coil bracket.

But, this brings up another Reroute question - I am using an Escort GT cylinder head, which already has a 5/8 coolant port pointed towards the cold side of the engine. So, If I use the cold side fitting to attach the Escort GT Oil cooler, wouldn't I need to plumb that back to the heater core, and run them in series? If I run the oil cooler and heater core in parallel, wouldn't that be too much bypass flow, and cause overheating issues?

The BEGi spacer has all the bungs and threaded holes, and the machined lip you need to simply slap it on and run with it.


Glad you liked my spacer.

Called Moss up and ordered it no problem.
