teedee88 Posted July 3, 2007 Share Posted July 3, 2007 Hi to you all. I have a 88 ser2 fitted with 3.5v8 on SU carbs, all fitted by previous owner. when I purchased the vehicle it was came with a "defender" type front end, full width radiator, with single electric fan. In an effort to make the vehicle look more standard, I have fitted a ser2 front panel, fitted a shorter spindle water pump which has allowed me to install a ser3 3core rad in its standard position. I have sourced and fitted a single electric fan and shroud, (in front of radiator and behind the grille) the fan is a "sucker"type. The expansion bottle is a standard LR black plastic type with screw cap. The pipe from the"overflow" outlet (by rad cap) is connected to top of expansion bottle. I have soldered an extra 8mm dia outlet in the header or the radiator, for connecting to the inlet manifold. So basically I would like to know what else should I do, and how to fill the sytem without getting air locks. All advice and suggestions gratefully received. teedee Quote Link to comment Share on other sites More sharing options...
Tonk Posted July 3, 2007 Share Posted July 3, 2007 just fill the system through the top of the rad, it should self bleed cos you have the header tank connected to the inlet manifold connection Quote Link to comment Share on other sites More sharing options...

Either you've got descriptions a different way round to what I'm used to or your fan will be shooting a lovely warm jet of air in front of the vehicle do you mean it sucks air through the grille and blows air through the rad into the engine bay (as it should)? For filling you could use an X-switch in the top hose and just undo the switch to fill the system Quote Link to comment Share on other sites More sharing options...
Jon White Posted July 3, 2007 Share Posted July 3, 2007 Having been there I'd suggest what you do is refit the defender front end and bigger rad. A series radiator is only just up to cooling the V8 on the road, and on a hot day, or with hard off road use it will overheat! For this reason I eventually gave up with the series rad and fitted a 90 front end and full width rad! Just fill and bleed in the normal way will be fine. However you need a different fan as Fridge says unless we've all got the wrong end of the stick! Jon Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted July 3, 2007 Share Posted July 3, 2007 Defender front end? Wash your mouth out Mr White! You can fit a decent sized rad in without changing the front panel, just chop all the cowling off the back of it and fit the biggest you can find - mine's sherpa-sized although there's not much Sherpa to it.

Ah yes Mr Utteridge, but you dont have a steering relay unit in the way anymore! I prefer the defender front anyway......... My V8's coming out soon anyway in favour of an oil burner....

FridgeFreezer Posted July 3, 2007 Share Posted July 3, 2007 Ah yes Mr Utteridge, but you dont have a steering relay unit in the way anymore! No, I have a PAS box directly underneath it TBH I reckon I've got no more or less room than standard, mind you it's so long since I've seen anything standard I prefer the defender front anyway......... Heretic! My V8's coming out soon anyway in favour of an oil burner.... Double heretic! Quote Link to comment Share on other sites More sharing options...
teedee88 Posted July 3, 2007 Author Share Posted July 3, 2007 Many thanks for all your replies. Just a thought, would a 4core radiator make much difference to the cooling, and is a thermostat necessary/ advisable ? Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted July 3, 2007 Share Posted July 3, 2007 Just a thought, would a 4core radiator make much difference to the cooling, and is a thermostat necessary/ advisable ? I wouldn't go to a lot of expense to buy a 4-core rad when you could spend a bit more and get something much bigger stuck in there, if you find one cheap then every little helps. A thermostat is most certainly advisable, as I understand it the cooling system needs the back pressure due to the restriction created by the stat to prevent hot spots forming in the block.
