Perkins cooling system

I've installed a Perkins turbo diesel engine in my 2a. Will the old expansion bottle from the Landy still work? Or will I need to put on an expansion tank with radiator cap?

Don't want to sound ignorant or owt, but why would you need to fit an expansion tank? If system heats (pressurises) too much and blows water, you should get something more efficient in the way of cooling (electric fan, military rad, bigger rad etc)

I assume that the Perkins engine operates with more water pressure, because there was an expansion tank on the Montego (which I forgot to remove, doh!). There is simply a plastic water bottle on the Landy, which even has an overflow spout. This will limit the pressure in the cooling system significantly. According to the Haynes Manual, the Perkins cooling system is "...of the pressurised type." I am therefore assuming that this pressure is needed. Please correct me if I'm wrong.

I'll get round to modifying an exhaust pipe for the old girl tomorrow, then she'll be ready to start. I'll keep an eye on the temp gauge, and update this thread next week.

PS. Does anyone know if the temp gauge in the landy will work connected to the standard thermotransmitter on the Perky?

Thermostats (wax) operate on water temperature. Rad and expansion tank caps operate on water pressure with different rated caps having different strength springs - At a higher temp more pressure in system - leads to opening rad cap (against spring). Wax thermostats use system in reverse (as temp increases, wax melts and allows spring to open 'stat). Expansion tank is basically just an extension of rad system. Landy expansion bottle is just a 'header tank' and as system cools, (theoretically) any necessary water is sucked back into system. Rad cap is just movedd from (I hate my 'dd' key - it'sstill F**kingup sometimes typingtwice,sometimesnot at all - think it's maybe compensating for missed 'dd's- along with spacebar - sorry) top of ra to remote location. RR's use exp. tank but this may be down to number of diff. rads and common exp tank may have been financially better that increased cost in necks (for caps) due to more complex designs and lower numbers of each rad - will explain more ifyou don't unerstand me (PM or in threadd).Mum runs 2.7td M**verick with exp[ansion bottle no probs...

No worries. I got the old girl going over the weekend with the Land Rover overflow bottle. Works fine, with no leaks or silly water pressure! Cheers for the input!

My father-in-law has a '59 SWB station wagen fitted with a 2.2 BMC engine, which, on occasion has managed over 50mph!!
He has the opportunity of a turbo diesel perkins engined montego estate, but was off put by the plumbing going to the turbo from some box thing on the passengers side inner wing??
Would it be possible for you to give a brief run down on how you went about the fitting to your landy? Is there a lot of work envolving the turbo? I could print this out and give it to him, maybe it would help him make his mind up and stop pestering me as to what he should do!!

The landy rad and bits are fine for cooling.

Benz, the plumbing from the box is probably the inlet from air filter to turbo, the fittings required are a couple of bits of waste pipe fittings and some rubber hose from the car.

If you want some fitting details, then my site lists how to do a home made adapter and I also have an active support forum for people doing the conversion where a few of us hang out and trade war stories.

there are other resources, the most complete documentation wise is wittsends:

Though you dont have to do things his way, especially on a series 3 there are a few differences.

Anyway i digress, if you bought your parts it wouldnt take long to do, and is a nice conversion, the tuneability of the injector pump is what makes it, i haven't altered boost or intercooled and yet I'm seeing a reasonable amount more torque, and more top end than a petrol, at around half the fuel consumption.

Turbo plumbing is straitforward and not to be worried about, it requires a few 50mm (? i think, but could be wrong) push fit waste pipe fitting stuck together to bring the inlet at right angles off the turbo up past the inlet manifold, turn horizontal, and then be rubber hosed onto oil bath filter ( I think there is a hose on the monty for it, mine came off a vw)

Anyhoo, hope that helps

Thanks for the links, looks like we may go ahead with this conversion??
