2008 CVO Ultra. But a new oil cooler on Ultracool, did the install checked every thing twice. Changed the oil and filter, started the engine no oil presure, loosed the oil filter had oil, Help!!!!!!!!!!!

 

How long did you let it run to determine no oil pressure? It takes a few seconds to prime normally after changing the filter.

Not sure how the cooler ties in to the oiling system, but if it has to fill before building oil pressure that could take several more seconds.

I'd manually fill the cooler and then try again.

 

I let it run for several seconds.killed it loosned the oil filter had oil started it again. killed it stared it again ran several seconds

 

If you have oil in the filter that tells me the oil pump is working. Now don't take this next part as gospel because I'm not 100% certain, but I think you simply need to get the cooler filled with oil and then the oil pressure will come up to normal.

I would disconnect the oil cooler lines and manually fill it with oil. Then restart the bike and see if your problem is solved.

 

Could i crack the oil lines bleed them

 

Bought a oil cooler from Ultra cool, installed on a 2008 CVO ultra, Everything working fine before I started the change, after installing the new oil cooler, changed the oil put on a new oil filter and put oil in filter before putting the oil filter on, started the engine noticed no oil presure,checked the oil level, was ok.

 

Ok... I just looked at the ultracool website to see how the cooler fits into the oil system. Also looked at my bike to see where the oil pressure sending unit is tied in.

The oil pressure sending unit is in the oil galley feeding the filter. Oil from this galley is routed through the filter, then through the cooler via the ultracool adapter plate.

With this setup, both the filter and the cooler will need to fill with oil before the guage will read any pressure. If you didn't let the bike run long enough to fill the filter and cooler you will not see any pressure.

Again, if it were me, I'd disconnect the oil cooler lines and manually fill the oil cooler with oil.

When disconnecting, look and see if there is any evidence of oil reaching the cooler. If yes, then you know your pump is working and one of two things is going on. You either have not run the bike long enough to fill the cooler and filter and build pressure, or the gauge is malfunctioning. If no, then you need to determine why not. Is the pump working? Is the oil cooler adapter plate defective or improperly installed? Have you run the bike long enough for the oil to reach the cooler?

There are several ways to troubleshoot this. You could remove the oil pressure sending unit and attach a mechanical gauge. By doing this you can determine whether your gauge is the problem. You could remove the oil cooler adapter and temporarily return the oil system to the stock configuration and see if the problem still exists. If that fixes the problem then you have isolated the problem to the cooler and/or the cooler installation.

When you started the bike, how long did you let it run? 5 seconds, 10 seconds, 30 seconds? Did the engine make any knocking noises? If it's not making any noises then I'd bet you do have oil pressure and suspect the gauge isn't working. If it is making noises then you really do have an oil pressure problem.

And one final thing. Before going through any of these steps above, are you sure you didn't simply disturbed the connector at the oil pressure sending unit while installing the cooler adapter? Check that first.

Good luck.

 

Disconnected the top line to the oil adapter filled with oil, started the engine had oil presure in about 20 sec, thanks for the advice it worked,

 

Alright! Glad to hear you've got it sorted out.
