Hi I have just. Fitted a very nice stainless exhaust I bought off zed I've been under the bus to check for leaks and there's a lot of air blowing out from the area to the left of the right heat exchanger I'm not sure if this is right or where it's coming from Any ideas?
It's not actually from the joints just coming down from the engine Does the fan ow air out anywhere other than the hoses for the heat exchangers? Thanks
yep type 1! Have you checked the hose from the fanshroud to the heat exchanger is connected correctly, when running quite a bit of air would blow out if this was the case
Yes, it's on ok there's nothing blowing in the engine bay or where it's attached to the heat exchangers, its blowing from the space between the heat exchangers and the rear bumper closer to the sump Al
I have been out for another look, the hoses seem ok Does air get blown out over/through the curved tinware behind the dipstick and exit underneath? Here Underneath its here But hard to get a pic
Are you sure it's not just the cooling air that's blown via the fan housing out under the cylinder heads ( if you look where the pushrods tubes are). I always mistake this for a blowing exhaust then realise its normal.
yes on the 1600 the fan attached the the alternator in the fan housing provides all the cooling for your van engine, only a small amount comes out of the two holes in the housing to blow through the heat exchangers. the rest blows down over the cylinder heads and also through your oil cololer matrix to keep your van cool. This exits from the vent for the oil cooler behind the gearbox on the left (passenger side) and out the back on both sides under the engine next to the sump. Someone please correct me if I am wrong about this! Ben
Hot air should blow out the back of the van from the lower tinware on both sides. It's the exhaust from the cooling system.
It's this little trick that makes working on them in the winter a joy. A little rev here and a gush of warm air over you. Not so much fun on a hot day but this is England so no chance of that happening What your getting is the heat from the cylinder heads as oil cooler ad a bit from exhausts the being blown away. It's when you don't get this that you have a problem.
Excellent tanks for everyone's help, seems its all normal, It's the first time I have worked/checked on the engine when it's been running Thanks Again Al
