I am going to upgrade to a 25 row oil cooler. I have two questions. Is it necessary to run a thermostat in the line when using one single cooler? I was under the impression it's only necessary if you run a second cooler.
Other question, What size fittings thread back into the oil pedistal and front plate? Is it 8 or 10 AN?

Thanks to anyone who can advise.

 

You need a thermostat. It's there to allow the oil to warm up to temperature before allowing it to flow to the oil cooler. Oil that never reaches a good operating temp will not lubricate as well.

18mm. You'll need to convert metric to AN.

 

I have an Earls 34 row, and I use -10 fittings. YOu can get the oil line adapter from Chuck at RE - but you can find them 1/2 the price if you call around. I used a thermostat inline for my single oil cooler.

The oil cooler is going to have different size -AN fittings, just check with whoever you get it from and buy the required fittings.

 

Thanks guys! I found the parts now that I knew what to look for.

Here are the links for future reference.

Oil Cooler and thermostat : http://www.amstreetrod.com/OilCoolersComponents.php4

 

AN to Metric Adapter $4.95X2 (unless you decide to get
this)

As the others have pointed out you are going to want a thermostat and the fitting size is -10 AN.

 

You might want to look into the Mocal as well. It's a little bit more, but you would have to buy less adapter fittings, so it's probably cheaper.

 

I assume with Mocal being British the fittings on them are metric eh?

 

Well, no those have AN fittings also according to this site.. http://www.racerpartswholesale.com/cooler.htm

Glass Man, why then would a Mocal cooler not need the adaptor fitting?

 

Earl's uses some universal fitting on their coolers, so you need to also order their adapter fittings for whatever AN size you require. With Mocal and some others, the fittings are part of the unit.

 

I'm sorry, what I meant is the Earl's thermostat looks like it would require four male AN unions, plus AN hose end fittings. Where as the Mocal you could just use the hose end fittings since it already has male AN ends.
On the plus side (I've heard) that the Earl's thermostat has a NPT ports for pressure and temperature gauges.

 

Ok I see that. Thats about an extra $20 for the pair of adaptors. Someone have a reliable link for the Mocal coolers?
Thanks again guys for the insight.

 

Here's the Mocal oil thermostat that is commonly used:

That Earl's one looks nice, too, but since it has female AN port connections, you would need four extra fittings (male/male AN flare to AN port fitting + o-rings, times 4, since you need one for each port) to connect it to your lines.

Thanks to all, im doing the same and i was to ask the same questions, im using a 25 row also "mocal"

 

Thanks Max.

 

care to do a write up when you are done with your oil cooler install

 

It should be pretty straight forward but sure I can do that if it will do someone some good.
I would imagine there are a few out there already.

 

on a side note, what makes the earl's and mocal oil coolers better than say b&m oil coolers? i know about the pressure differance but its not that much better than b&m's. also from experience its the lines that leak not the cooler. any info would be great. thanks

 

I'd be curious to know what the total cost comes to for the kit when all is said and done. Also, before and after oil temps as well. That's one gauge I don't have, so after I install my dual 19 row mocals I won't notice a benefit on the water temp reading until I hit the road course.

 

How are the lines laid out when using dual coolers?

Can you just run the return line from the first cooler to the inlet of the second, then run the return line from the second to the block?

This seems like the easiest way, since the thermostat on the first cooler will regulate temp.

thanks

 

Hey guys I wanted to upgrade my oil cooler. I am running 15 lbs and about 410 wrh, its a daily driver, but I wanted to do some cooling mods. Should i go with the 32 row single cooler or the duel 25 row coolers. Refering to the Earl coolers.
thanks for the help

 

Dual 25-rows should cool significantly better than a single 32-row, especially if you have the stock bumper.

 

Do you road race the car? If not, don't bother.

 

While I agree with Mahjik's statement in general, at your power levels, you might want to get an oil temp gauge. If you are seeing excessively high temps just boosting around, you may want to consider an upgrade.
