Hi.
I have a D16a8 from an Eg so (Audm) in my ef crx. I also got the power steering pump, brackets too.
I bought a belt on ebay with the model 4Pk0815 and tried to install today. The ribs all line up fine but the belt is too long. I'm guessing I need a good 2 inches shorter.
The pump was at the highest spot where it meets the bracket and the tensioner was maxed out. I think the belt is about 32 inches . Does anyone know which exact belt I should be using? Does anyone know how to read the model numbers of these belts? 815 =815mm?
Thanks

 

Can you snap a pic of the belt routing on your P/S system and post it here ??? Yes, the labeling system does in fact measure the belt length in "mm"... as in 4PK0815. If you flip it, it usually means that the length is measured in inches (SAE) as in 320PK4. Both belt part numbers that I have quoted would be the same length within the same brand. The trick is some brands measure the INSIDE of the belt and other brands measure the OUTSIDE of the belt... so not all 4PK0815 belts will be exactly the same !!!

I suggest you minimize the pump height and lower the tensioner as far as you can... take a long piece of wire and wrap it around the same groove of all pulleys, mark it where it meets itself and measure that length. Add 1/2" or 15mm to that measurement and order that sized belt.

 

Yes will definitely try that as a last option, the engine bay is extremely tight.
Was hoping someone has the civic stock with the d16a8 so they'd know straight away.
This one could definitely be 40mm shorter by just guessing (thats how loose it was).
Learned so much about belts just from this lol
No pic, but when i put it on it was definitely around both pulleys.
Couldn't use my old power steering pump because it used the V belt and the crank has the ribbed. So had to get the matching EG si d16a8 bracket and pump and high pressure hose connector adapted.
