Heat exchanger and Oil cooler advice

The moderator has told me not to post the humble pie video, as there might be people under 18 and your face may scare em.
 
FARSCO - Tony heart will be in touch ? ? ?

Right - if I was to use rydlyme what diluted mix would I be looking at for the heat exchanger?

Right - new aftercooler arrived (wont be so hastey next time) - 5 ltrs pf Rydlyme on order hopefully arrives tomorrow.
will come back to heat exchanger cleaning later

so oil cooler is complete lightly sanded the ends and just a light rodding very little build up of lyme.
am I correct that the end caps are bolted up dry without thread lock/locktite to a standard m8 torque of 25nm ?
when I am installing back on the boat the housing that it mates to as Bruce has pointed out goes on dry (I will need to clean that face up first) is there a torque setting for the four mounting bolts and again do they go on dry?

Tightening torques
Tightening torques for vital joints that must be tightened
with a torque wrench are listed in workshop
manual “Technical Data”: “Tightening Torques” and
are contained in work descriptions in this Manual. All
torques apply for cleaned threads, screw heads and
mating surfaces. Torques apply for lightly oiled or dry
threads. If lubricants, locking fluid or sealing compound
are required for a screwed joint this information
will be contained in the work description and in “Tightening
Torques” Where no tightening torque is stated
for a joint use the general tightening torques according
to the tables below. The tightening torques stated
are a guide and the joint does not have to be tightened
using a torque wrench.
Dimension Tightening Torques
Nm lbt.ft
M5 6 4.4
M6 10 7.4
M8 25 18.4
M10 50 36.9
M12 80 59.0
M14 140 103.3

Right Rydlyme is expected to arrive tomorrow so please correct me if I am wrong here.

I poured in today fresh water to see how much the exchanger holds which was just over 2 litres - So when I come to clean the exchanger tomorrow I mix 1 litre of water and 1 litre of rydlyme into the exchanger which is stood up.

now from my understanding I now wait until it stops smoking/bubbling the flush with cold tap water thoroughly ?

pretty much yes. Rydlyme give a duration of 4 hours IIRC. You dont have to leave it in after it's cleaned if it's done it's business in whatever, 30 minutes whatever for the reaction to stop. Once the reaction is done it's done. Remember to check with rod. Instructions are included or downloadable.
