Water Pump and Thermostat Replacement

[Otto Man]

Hey There
Long time no post.
When the 30 inches of snow melts and the robins come back I want to replace my water pump, thermostat (180 degrees), and a new thermostat housing. I am a little picky for NOS, or equal, parts. I don't want to go lower, but if I must I'd go billet stuff.
If anyone knows of source or sources please let me know.
Thanks a Lot

.......maybe we can get together on your coast in a few months?

I bought my water pump and thermostat at my local Ford dealer last year, they didn't have any problem getting them. Although i do not know about the housing availability.

Factory thermostat is 192/195. You don't want a 180 one.

Mike, why not the 180?

Thermostat only determines minimum hot opp temp - nothing to do with peak temps under higher thermal loads (that's determined by the coolant, coolant flow, radiator capacity/volume/surface area/airflow thermal load, etc.).

We want the engine oil to reach water-boiling temop (with a closed Type 4 PCV system that is usually >205F) on every run cycle (running for >10 minutes) to boil off the previous cooling cycle water & fuel vapors that accumulate in the sump (oil).

Otherwise the oil gets full of fuel and water solids and gets dirty (thus not much of a lubricant) quickly.

BTW - I have a bag 'o goodies for you. Your XMAS present for 2015. I just got too busy/lazy to send them to you. If I remember, I'll bring it to Knotts.

Mike, that is too kind. Thank you very much.

Unfortunately both Rose and I areunemployed so thanks to King Obama Rose and my ACA and my Medicare Supplementalpolicies we are paying $900+ each month for insurance (affordable yeah) we maynot make it there. But Rose still says we will be there.
Can’t wait for schedule (dates)and hotel info.

Hey Mike...this other "so-called" SVO master says this:
"Thats why we do not run an oil cooler or should i say an oil cooler monitored with a temp gauge. We also need the oil to boil off the moisture. But water temp is the number one reason for cracking those exhause seats, We even cracked ones with stelite seats on ocassion. Those exhaust seats do not get adequate cooling by design"

[MikeFleming]

But water temp is the number one reason for cracking those exhause seats, We even cracked ones with stelite seats on ocassion. Those exhaust seats do not get adequate cooling by design" It's not the coolant temp that is the issue - it's the 1900 F+ exhaust gas temps that cannot be drawn quickly enough out of an iron head. The poor coolant flow around the exhaust ports and seat/chamber area doesn't help either.

The seats live much longer if EGT is limited to 1650 F (stock levels) - it's the mod'd engines with manual boost control that usually get above 1800 F. Not much will handle those temps for long especially an iron head.

In any case a lower temp thermostat will have absolutely no effect on peak temps. Maybe a couple minutes longer on how long it takes to get there though - about 1 lap more on-track. Negligible in a 15 minute session.

The SVO engines come with a "heat exchanger" as an oil cooler. It heats the oil sooner - using coolant flow - and also helps suck the heat out of the oil when it gets hitter than the coolant. That's two pluses, if you're counting.


... we are paying $900+ each month for insurance (affordable yeah) ... I was once offered a $2500/ded/year, 80% coverage plan from Blue Cross of California for $600/mo - in 1976! So for today's coverage, $900/mo today )at our ages) sounds dirt cheap.

I'll look for a box.
