I had a Pontiac 400, my friend gave me a 455 block. I line bored, and cylinder bore .040 over. Had my 6x heads redone. It would hit 240 degrees at a red light. That was 20 years ago. I miss my trans am.

[@FastMonty]

Yeah, that's hot... and, not unheard of. Get another TA! :) Thanks for the comment!

Thanks for doing these videos. You are helping me through my own build. I'm building a 1965 Catalina that has been stuck in my showroom for 25 years. we are doing the March serpentine system as well as Vintage air and Ron Francis wiring. I wish we lived close I think we would be fast friends.

[@FastMonty]

Thanks James... Glad my videos are helping. Keep up the great work! And yes, the FMG family should buy an island, and racetrack, to all hang out, all the time. ha, ha... See ya!

It may be an anchor but I still have most of my WZ engine. Glad I kept it.

That's a keeper for sure!

I made the first FlowKooler water pumps at the Brassworks in Turlock Ca. back in 1985. The solid impeller keeps the coolant from cavitation compared to a stamped impeller that looks like an alternator fan. If you have a water pump that has a solid cast impeller already there won't be any difference.

[@FastMonty]

Wow, cool story... thanks for sharing the differences... the other nice thing about the Flow Kooler pump is the clearance in between the fan and divider plate. Thanks!

[@stanojeda523]

A huge thank you for posting this video! I’m not a mechanic nor handy with cars, but I wanted to change my water pump to a Flow Kooler in my ‘65 Goat. I followed your video and easily installed the pump. Results...20 degree drop in temperature!

[@FastMonty]

Thanks Stan! That means a lot... I'm so glad I was able to help out another enthusiast. Thanks again for the feedback. Hope to see more comments from you in the future.

[@Ayden-wt4xi]

I don’t want to assume, but would it be fine to reuse the two o rings for the sleeves if your old o rings look completely fine?

[@FastMonty]

yup, as long as they still have some "rubber" spring to them as you compress it into the timing chain cover... if that makes sense?

[@Ayden-wt4xi]

@@FastMonty that does make sense, they both have no tears or cracks so they look to be good to reuse I’m just trying to save some money haha.

[@Buckriverjd]

Thanks for the videos! Note: 68 pump has two plates, not zero, and does not have the two tubes.

[@FastMonty]

Thanks JD! Two plates! Sounds crazy! ha, ha... thanks again for the added info.

[@Mechanickirk]

I gap my divider plates no matter what. The method I use is to hammer the plate down to the impeller till it just touches without gaskets and then use the gasket as the shim. I'd be concerned painting the divider plate as cavitation could lift that paint off and stick the thermostat or gum up water ports. Good luck with that.

[@FastMonty]

Good tip on modifying your own divider plate. As for my painting of it, Por15 will not come off. At least, that's what I was told. Ha ha. Thanks for chiming in.

[@frekkledipped]

@@FastMonty I painted mine with Pors after seeing how nice yours looked and the paint has been coming off. Ive drained it a few times to clean it out still little bits coming I must have forgotten something.🙁

[@CalicoRiot]

I'm considering this pump, would you recommend doing this with the motor in the car? Did you do their timing cover also? I'm in the middle of pulling my intake to cut and paint it and even though my pump works great, it doesn't look great. Thoughts?

[@FastMonty]

Yes, this pump is great, and you can do it while the engine is in the car. I'm not familiar with their timing cover? If you do elect to change pumps, I'd recommend painting the edge of the divider plate that's visible in between the pump and timing cover. Have fun!

[@davidsutton9148]

Quick question… I’m running the later 11 bolt Flowkooler pump. Do the rubber sleeves need to be in contact with the divider plate, or should there be a gap? Mine seems to have about 1/8” or so, I can wiggle the sleeves and feel that there is a little room. Thanks, and your videos are fantastic!

[@FastMonty]

That's a great question. My impression was the sleeves do contact the divider plate when everything is bolted together. But, I honestly never double checked that. A 1/4" gap seems excessive to me. Let me know if you figure out the real answer, and I'll do the same. Thanks for being a part of the channel!

[@davidsutton9148]

@@FastMonty trusted sources tell me that the sleeves should “gently and firmly “ butt against the ports on the divider plate. I’m going to slip a couple of 1/8” thick 1” inside diameter o-rings on the sleeves to resolve the issue. Or maybe cut some 1” heater hose into 1/8” ringlettes. Slip them up to the shoulder on the sleeve and should be good. Thanks again for a great channel.

[@FastMonty]

@@davidsutton9148 Yeah, I agree. I urge you to figure out "why" they're not touching, as there may be another issue going on. Let us know what you find.

[@diegomarroquin5021]

[@funhumanusa]

[@mstewart7804]

I've got a newly rebuilt 1969 Pontiac 350. It's got some overheat issues. I'm just wondering why the hot water from the intake goes directly into the water pump. Mine is the same way and I havn't found anything online yet about it. If you could awnser here that would be great, Thanks, loved the video.

[@FastMonty]

Good question... the water goes from the water pump to the intake manifold, and into the heads... then comes back through the block, into the water pump. When the thermostat heats up, it opens, and water goes up and out, into the top of the radiator. That's the flow. Did you use a laser thermometer to verify the temperature? When I first rebuilt my motor I used a GM/Chevrolet temperature sending unit, which is WRONG. If you're using stock analog Pontiac gauges, your temperature will read 50 degrees too high. So, make sure you have a PONTIAC temperature sending unit, and verify your temperature with a laser thermometer. You can get one at OPGI. here's the link... www.opgi.com/gauges-accessories/sending-units/temperature-sending-unit3/sending-unit-temperature-1964-72-w-gauge-kr00611.html Thanks for watching! Let us know what you find!

[@R0yL33]

@@FastMonty Water gets pumped into the block first, then up into the heads, then to the x-over in the intake manifold. If the thermostat is open, hot water goes into the upper rad hose. Some water is always recirculating from the x-over back into the water pump so you still get some circulation even when the thermostat is closed. Even when the engine is warming up, water around the exhaust seats is quite hot, and you also need water to flow past the temperature switch (edit:) and thermostat.

[@FastMonty]

@@R0yL33 Thanks Roy, you're right. I was focused on the water exiting the manifold through the top hose, and that water from the intake does not go directly into the water pump. Must've been too tired when I was thinking about it... ha ha. Thanks for the comment!

[@MrSticks9999]

@@FastMonty I've been working with "rust" for a long time. POR, I'm not a fan. There's better materials.

[@FastMonty]

@@MrSticks9999 Been working good for me... what do you use?

[@MrSticks9999]

@@FastMonty The problem with POR is that #1 . . it will peel. That happens because it's adhesion is not good at times. It's a very hard material; once cured, but that does nothing for you if it can't "hold on" to where it was applied. #2 The surface is critical for POR. It even says new metal is not where it should be applied. Even perfectly clean metal, it lacks adhesion. A much better material out there is Master Series Silver. It is a primer, but is also moisture cured as POR is. It can go over any substrate, rusted, clean, chemically etched, etc. That is a huge difference. You can top coat it with anything, literally. Check it out. I've been using it for over 25 years.

[@FastMonty]

@@MrSticks9999 Agreed that POR 15 has to be applied correctly, and I've never had an issue with exposed steel. Anyway, will check out Master Series Silver. Thanks!

[@funhumanusa]

1979 Trans Am Pontiac 400 motor. Be warned installing a Flow Kooler water pump makes serpentine belt conversion kits a nightmare installation (CVF). Use the Recommended pump!!! Nothing is designed to deal with varying boss heights as shown in a later video. Working on an engine stand is not reality. HOURS trying to make it work.

[@FastMonty]

Yup, It certainly takes some patience if you deviate from the originally designed kit. But, it can be done. Thanks for the PSA
