Cleaning out the bottom end of a M20B20

[Five Star 0]

Gotta clean out all the coolant lines, due to oil + antifreeze. Not nice stuff..

Any ideas on the best way to flush it? It's still in the car, with the head off.

I'm replacing all the hoses etc..

A good steam clean should get most of it out and then once you get the motor running use a good radiator flush to get residue out of the heater matrix and places you havent been able to clean properly.

We use a special product from PDC Direct Ph. 021892179 or 0800100544

Its a special engine de-oiler thats not sold retail. Radiator repairers use this product

Works a treat...used it several times..... Audi's blowing oil coolers

Do it twice before you do the final fill with a good antifreeze..we use genuine BMW.. its only $15 a bottle (1.5 Litres) you will need 2 bottles.

A steam clean? I thought that was for the outside of the motor..

How would I go about doing that?

I'll give you a call monday glen, but if anyone can give me any hints before that that'd be much appreciated....

Cleaned out the bottom end with a nice moulded bit of hose and a lot of fabric blocking up most of the holes for coolant.

I also got that product, thanks glen. It arrived about 12 hours after I called the guy.. he sent it before the money was even in his account!
