| Upgrading the Radiator and Cooling Fan on a 1969 MGB Roadster |
In all the 18+ years of possession of our 1969 MGB Roadster it's ne'er hot, however a minor leak from the radiator in 2016 necessitated its amendment therefore i made a decision it absolutely was the proper time to upgrade the cooling system in preparation for subsequent eighteen years.
While checking on costs for a replacement radiator I discovered a corporation within the European country providing Associate in Nursing atomic number 13 radiator for not rather more than a typical one, therefore ordering was a no brainer. luckily I ordered this regarding one month before British people voted to depart the EU and also the Pound plummeted against the monetary unit.

As the whole cooling system had to come back apart i assumed i'd conjointly replace the engine driven radiator fan with an electrical one. I actually have fitted Kenlowe fans to my cars within the past and whereas they worked dead well I had 2 problems with them. first off fitting with their universal fitting kit was ne'er that correct Associate in Nursingd invariably looked alittle untidy and second the device was an odd bulb arrangement that fitted within the head of the radiator and slotted into an additional seal, that I found troublesome to form watertight.
This time I opted for a Revotec fan because it fastened each these issues. every fan comes with a optical device cut atomic number 13 frame which inserts onto long bolts in situ of the traditional ones and also the device is embedded into a special section of atomic number 13 tube that along side 2 short hoses replaces the traditional convoluted prime hose. The Revotec came complete with a decent set of directions and every one necessary wires, connectors, and even a collection of cable ties to neaten the wiring.

Inevitably my work concerned in commutation the cooling system does not stop there as whereas this was far from the engine compartment I clean it up the maximum amount as attainable. The radiator surround and growth tank, I had antecedently fitted, were removed and painted with black Smoothrite and also the pump hub in yellow. The inner wings were clean, a couple of areas touched in and every one polished. I replaced the lower hosepipe, housing breather and oil cooler grommets at a similar time whereas I had quick access.
Everything was put in comparatively swimmingly and with no issues. I wired within the fan and controller loosely to form positive everything worked properly, before I committed to cutting the wires to size and fixing it as tidily as attainable.

The MGB all unemployed up initial time and surprisingly there have been no leaks from anyplace. The controller worked well and once permitting the engine to heat up and also the fan cut in OK. It took a couple of cycles to line it at regarding the proper operational temperature. a decent tryout in varied conditions conjointly proved prospering, still while not unseaworthy. The Revotec works very well generating an enormous air flow that cools the radiator terribly quickly and cuts in and out swimmingly. My solely criticism of Revotec is that obscurity within the directions did it say what ampage fuse was required to the fan offer. a fast Google search found this on the Revotec web site. therefore why on earth do not they embody it within the written instructions?
In theory removing the engine driven fan ought to conjointly unharness a couple of further bhp however no-one ever aforementioned what quantity. however because the MGB was originally solely ninety five bhp, and presumptively over the years this has born alittle, even solely a couple of bhp may build a five-hitter distinction though there wasn't any noticeable distinction throughout my tryout
