351 cleveland correct thermostat

[Nadsengineering 0]

Hi guys, im new to all this forum stuff so bare with me, I know this topic has probably been repeated heaps, but I am looking for a correct thermostat to suit 351 cleveland, the one that seals off the bypass brass port correctly.

have been running tridon high flow but i believe i am needing the correct 333-180 type.

Have searched high and low to no avail and local parts shops are not helpful at all, they will get me a dayco dt66a thermosat, but open the box and it is a windosr type that is marked 330-180 

Looking forward to hearing what thermostat everyone uses and any other suggestions and where they source the correct part

 

kind regards

Hi BGDAV, thanks for the reply mate. Can i please ask what thermostat you got? Part number and pic if thats not to much trouble. Repco and sprints have been getting the right part nunber in, but wrong thermostat in the box. Cheers mate

I got a Dayco one from Repco for my Clevo. Sorry cant remember the number but it works fine.

Yep, it seems hit and miss, last two i have ordered from local repco have been windsor style one's not clevo. Somewhere along the way they have been put in the wrong box i think.

If your clevo has the brass plate installed in place then even the standard thermostat blocks the bypass,,, when it opens the plunger slides into the hole allowing 3/5's of stuff all to go back through and directs it through the radiator,, the foot type seals it like a tap washer,, I've been running std type 160's for years and mine always run cool,,, if your clevo runs hot I'd suggest you have other issues to look at as well. I run EF thermo's and 3 core radiator

I run one out of a CASE IH tractor, opens up huge, no problem with flow.

An old ford mechanic told me about it years ago, cant remember the part number though but might be able to find out if you need it.

You need to be careful with clevos that you don't remove too much restriction from the pressure side of the system, as this causes cavitation in the pump impeller and flow actually reduces, even stops in some cases. Clevos are among the worst in this aspect, especially above 3000 rpm. I saw a video of a clevo pump spinning, filmed through a Perspex cover on the back of it. The water formed a huge bubble in the centre of the impeller and flow slowed right down. Amazing to watch.
