Coolant flow diagram/theory and thermostat placement

[azgolfrat]

Hi Guys,
I am trying to gain a good understanding of coolant flow in my 03 Marauder... before I drop in the new reisch 170 tstat. I want to make sure I put it in right position wise, but I also want to know "why".
Anyone versed enough to explain?
FYI - I have installed the mod connecting coolant flow between the rears of the cylinder heads.
Also, since I'm still building, I have no coolant in the system right now.

Thanks

Your in luck as I just changed all my hoses and installed a new Reisch 170 stst.

List of the hoses you'll need:

Lower radiator to thermostat housing: Gates 22812
Crossover to top of radiator: Gates 22810
Crossover to thermostat housing: Dayco C70986
Oil cooler to thermostat housing: Dayco E72103 (you will only need a portion of this hose), lower radiator hose for a 2004 Lexus GS300. Reuse the old spring
Reisch Performance Thermostat: FORD-4D
All other hoses are bulk items at any FLAPS

The thermostat actually mounts upside down. The top of the thermostat (part with the arch) will be facing towards the ground. The threads of the thermostat housing bolts will be pointed up.

BTW... your tune needs to be adjusted per Reisch's recommendations.

Any questions, ask away.

The system is set up to circulate the water just thru the engine until it warms up. Then the t stat opens to circulate thru the radiator to keep the engine at the proper temp. Its done this way for emissions to get the engine up to temp quicker.

Thanks fastblack!
Based on your reply, looks like I did put it in correctly. I noticed that even in the "closed" position, it looks like the tstat allows flow back through the shorty hose to the block connection near the oil filter...this must be the method for block/head recirc until the tstat opens?

As far as the tune due to the Reisch addition, ..oh yeah. Adding a V7-JT supercharger as well.

I am wondering, is this tuning something I can do...I've read several "professionals only" comments; True?

Thanks again

I wouldn't recommend tuning a blower car yourself. Air/fuel/timing is critical..see member here Marty Ochs or call them, Mo's Speed shop, Dallas,GA. they can give you a base tune then adjust by you datalogging

I wouldn't recommend attempting to tune it yourself. Get a good base tune from MartyO then take to get a final dialed-in tune.

Its done this way for emissions to get the engine up to temp quicker.

This system also gets heat blowing into the cabin much quicker in cold weather.
