I've never put a thermostat in hot water to check one before, never needed to. So yesterday I found about 3 laying around my garage and decided to check them. One 160° Stant, one 180° Stant and one 195° Robert Shaw. Every article I've ever read on cooling says the rated temp is the start opening...

I've seen ads and I've seen posts where people say that their electric fans keep their engine cool "even" in 90° heat. For reference, 90° is not hot. We always say "my 600hp engine is cooled by 'x'". When we are driving, we are driving a typically higher compression engine but using only about...

Well I'll finally get a good test of my cooling system and a/c next week. 110 last week and did well. Had a 115 day last yr w electric fans that did well in slow traffic and idle but horrible on interstate. But next week I finally get a real world test of my mechanical fan and factory shroud.

A person observation, I have seen many car magazine articles touting electric fans and aluminum shrouds. They all swear by them and in cooler climates, where all the articles take place, they seem to work. I've used 3 different electric fan n shroud setups. 1 was from a Ford Contour, kept...

I've posted numerous things about my engine temp saga on my 496. Finally went w a direct drive mechanical fan as there is no room for a fan clutch. On 80° days, engine runs about 175 in town and won't get over 165 on the highway w a 180 t-stat. Haven't tested in the summer when it's 126° out...

I purchased a Cold Case Radiator part# MOP754A based on their website listed dimensions. States "Overall" thickness 3". I have minimal clearance and 3" is max I can go. Got Radiator, it is beautiful, but it is 3.25" "Overall" thickness. Fan blade will hit bottom tank edge n then core when...

1967 Coronet, fresh 496 stroker, new wp, wp housing, aluminum radiator, hoses etc... did a few flushes of cooling system to make sure all passages are clean after machining. Pulled radiator and out of curiosity, looked in bottom radiator opening. The tubes are covered in some sort of gooey gunk...

'67 Coronet w 496, about 610hp in 110-120° typical daily summer temps. Waiting for Derale 6 blade steel reverse rotation fan. Will be direct mount, no fan clutch, and using the factory shroud. I have dual electric fans that do great at low speed n idle. But at highway, gets up to 220 on flat n...

https://flowkoolerwaterpumps.com/blogs/cooling-resources/doesnt-coolant-need-more-time-in-the-radiator-to-cool I bought a triple pass radiator to cool my 496 engine. Well at idle I'm good. But at highway speeds it gets 220+. It's closed loop, reservoir can, no air pockets, great airflow...

Having a hard time cruising at 60 in 115 temps keeping engine under 200. It's regularly 220. Custom aluminum shroud w 2 high cfm electric fans. Idles at 190 w a/c on for 20 minutes. Want to find a shop that will rebuild a Hayden low profile heavy duty fan clutch w a reverse rotation heavy duty...

Ok, I did my due diligence and looked through the 218 posts that list heater control valve. 1967 Coronet w factory air. Leaking heater control valve both down the outside of firewall and inside. Thankfully it was only distilled water and a radiator pressure test that discovered it. I have looked...

Here's a mockup of my Ford Contour electric fans n shroud on my 26" radiator. With trimming, it fits my '67 Coronet with serpentine pulley setup. Should fit stock v-belt setup w out trimming.

Ok, steep/expensive learning curve. I have a 1967 Coronet with a 496 stroker in it, serpentine pulley system with reverse rotation water pump and a/c. I live in Fort Mohave AZ where we regularly see 120+ temps from June thru Aug and 100+ from middle of April to beginning of Oct and mid 80's from...
