The cork was only in 2"x4" strips down either side of the Intercooler, I'I' follow this up tomorrow, going to bed. Excellent points to take into consideration. Thank you.
Removing the cowl along with the viscous improves RAM air flow so that no fan is needed most of the time above 30 mph.Just make sure the radiator is clear of debris. And that the viscous fan is working properly. If you have a pre 1999 model you can rig the aircon fans to assist cooling in extreme conditions as per Keith's mod. But removing the viscous and shroud that draws air through the entire radiator surface area and fitting an electric fan that draws air through a relatively small area seems a bit daft to me. That is why after second thoughts i never fitted the 17" electric fan i bought.
Only on a diesel.No, you remove the fan and the cowl from memory.
Is the car petrol or diesel? (save me reading the whole saga). If diesel, the car should run happily using just the aircon fans with my mod as long as the viscous fan and cowl have been removed. Petrol, the aircon fans can only be used as back up for a dodgy viscous.Before I owned the bus, it had a new radiator every year for three years??
Turned out the bigger intercooler has a risen weld bead that was rubbing into the core? I solved that by lightly filing the bead and fitting cork in-between the two rads.
Wammers said fan shroud a while ago... (he's always right)
Time to rip out and rebuild the fan setup with a shroud this time...
**** fück... Answer found I think...
Home work required, I had removed the original shroud as well. I do still have it and I'll have to make an other to suit the fan position. It's offset to miss the water pump pulley.
You can improve the cooling on the diesel by fitting a RAD from the GEMS V8, top hose stays as is, bottom hose needs a bit of plumbing.
If you heard it before, it was from me It's pretty much a straight swap I believe although the side plates may need to be loosened to slide it in. I have not yet tried it, this was done in liaison with a guy in New Zealand who had overheating problems when towing after fitting an M57 engine to his P38. The GEMS RAD which is hot in at the top, cooled out at the bottom, unlike the stupid RAD on the P38 diesel, improves cooling by a guestimated 30%.Heard that before somewhere. How easy is it given the intercooler is in there too?
Agreed, but all I've done is fit an electric fan. Nothing modified heavily?
As said the fan does bugger all at speed but still when at speed with the Aircon on it'll heat up, at least on that occasion it did..
Agreed wammers, the air con was on to cool us down Inside not to help the engine, as it is not wired to help cool the engine..
1st case was sat in traffic, the temp climbed.
2nd case was while we were moving at 70mph/110kph it would rise again while using the Aircon.
I should be able to use it without any worries id of thought?
The fan only helps on static traffic and upto a certain speed. As you know, so why would it lead to an overheat when using the Aircon as I should/could?
But then yesterday all was ok..
Sat stationery for 20minutes Aircon full blast and revs raised occasionally to help heat the engine all with the bonnet closed and not a eyebrow raised... It all could just be outside temperature but then these cars were built for hotter countries as well...
I think a strip down of all the radiator section to check for debris in the vains is the only answer I reckon after a good flush of the interior..
But at 70 mph the fan wouldn't run (in theory) and also there is no restriction from a shroud?
I understand what your saying wammers. Im not arguing with you, you know...
The latter almost rhymesI was talking in slow traffic or stationary in traffic after a burst of steady speed. At speed the engine produces more heat, the latent heat has to be got rid of when you slow down. With the shroud in place air is drawn from the entire rad surface. Your setup does not do that as explained earlier. If the engine runs at normal temp with aircon off, then the aircon being on MUST be contributing to your problem. The condenser gets bloody hot, the first bloody hot being drawn or blown onto a second bloody hot won't cool the second bloody hot down a lot.
