Car is leaking coolant from somewhere around the oil filter while the car is running. Have climbed under the car while it's running to try and pinpoint further but not having any luck.
This is my first Prelude, so not familiar with the engine. Any help would be appreciated.

U.K VTEC

The coolant drain bolt is located right next to the oil filter, could be that? Also, between the oil filter and the block is the oil cooler which uses the cooling system to prevent the oil getting too hot and that has a hose which tees off of the main coolant system so it could also be that which is leaking. However, you have to be sure that the leak you have isn't actually higher up and is simply running down the where the oil filter is located, giving the impression that it's from that area.

Hope this helps

Thank you for the information. I tried to find the leak by looking topside, but can't see anything because of the injector fuel rail and everything else in the way.

The oil-cooler o-ring is known to give out over time. Easy fix.

Umm, he said it leaked coolant, not oil

But it sound like you have a leak from the oil cooler, but it could also be from the thermostate housing which is located over the oil cooler, but under the intake. It has a large black metal pipe going from one side of the engine to the other.

Ah yes...

It was a couple of coolant hoses behind the intake manifold.
Thanks for the help.
