Mains electricity engine oil heater that is permanently attached to the engine sump. Refer company website for details: http://www.wolverineheater.com

Sump base is cleaned and abraded as per fully comprehensive installation instructions. Product is then applied to the sump, pressed on using the applicator supplied and sealed with high temperature silicone supplied. Electrical cable is then led up into the engine bay and secured in a convenient location. A replacement plug may be required.

About 30-60 minutes before using the car, raise bonnet and connect up the heater plug to an external power supply. Detach and stow plug and cable before driving off. Sump and oil will be generously warm.

1. Easy to install.
2. Works like it says on the box.
3. Small and thus unobtrusive.
4. No plumbing into the water system.
5. Although intended for serious use by Americans and Canadians in deep winter, it's wonderful for hobby motorists wanting to warm up a cherished classic's engine.
6. Fast warm up of cold engine [cf. 30-60 minutes] and accelerated attainment of full operating temperature once on the road.
7. Comprehensive instructions.
8. Fast and reliable online ordering from an old school values American company that puts a value on its customers.

1. International shipping cost. [Best to order more than one at the same time [e.g.] organise a bulk group order.]

1955 Rover 90 - four years in service. 1969 Rover 2000 - two years in service. [Note the 90's painted sump required a patch to have the paint removed and the steel abraded - as per the installation instructions. The P6 sump simply had to be degreased and lightly abraded.]

Highly recommended.

Most people over here don't have easy access to a mains supply when they park by the side of the road

Self evidently the product will have its greatest appeal to those P6 owners who store their vehicles within easy reach of a mains power outlet. I didn't believe there was a need to mention that. :roll:

Cheaper than I expected!

That is cheap. I looked into getting one of those for my truck, and there are companies that do them in the UK, but from what I remember they were a lot dearer than that. I was always worried that it was going to fall off of a rattly old diesel....
I wonder if it has to be stuck on, or whether it would be feasible to have one on a little wheeled trolley so that you could press it up against any engine in your fleet?
I suppose direct contact of metal to metal would always be more efficient, but the losses cant be that big?
HI, ISTR Rover used to offer a mains powered block heater that screwed into the water
gallery on the 3 litre 6 pot in P5s.

Anyone recall the little paraffin heaters you used to put below your engine at night ?
My comment about not many people having electric supply near their parked cars must surely also affect the growth in electric cars , not hybrids .
In Canada and Alaska where a car has to be parked out overnight in the deep winter folk run the heater power cable out to the front grilles of their cars to connect up an extension cable from the house or condo when they first get up in the morning. By the time they are ready to go off to work, the oil is warmed up and the extension cable can be disconnected, rolled up and taken back indoors.

[I recall the Old Man saying that in WW2 during the winter of 1944, it was so cold in Belgium and Holland that he had to drain radiator and the engine oil overnight. The engine oil was warmed it up on stove the next day. Removing the battery and bringing it inside was also SOP. When not otherwise available, obtaining boiling water for a wash and shave and some warm water for the radiator involved "testing" the Vickers machine guns.]
I do remembera recalcitrant Bedford CF diesel on an ice climbing trip to the Cairngorms. It was particularely cold even by Scottish standards and the oil in the gearbox froze. We managed to start the engine with copious quantities of easy start, but the gearbox wasn't going to allow any of the cogs to move at all. Eventually we finished up with a small camping GAZ stove nuder the gearbox - and another, larger, camping GAZ stove under the first stove to warm the gas in the first one sufficiently to burn well enough to heat the gearbox up.

Hmmm... the risks we take when we are young!

I have a new Bray make heater in the garagehttp://www.historyworld.co.uk/adv ... +Parts+etc ,
it said Range Rover on the box. It is the type that was fitted by cutting the radiator hose and fitting in the gap. It then had a remote wire with a socket to fit anywhere, for plugging into the mains at night. They were quite common in the 40/50's. I have had a couple of Standards with them fitted when found, but I threw them away, as when left for years in a radiator they had rusted up.
I think if it ever gets cold enough to need these sort of things , it's Nature's way of telling you to stay in bed
But I am a Southern softie
Does anyone know what thread that the side plate heater socket is? I found a few screw in heaters on a tractor parts site, which are all pipe thread, they seem to come in 1 5/8 inch pipe thread, and 3/4 inch pipe thread. They only seem to come in 110 volts, so only good for the US.

Some while ago I bought a Webasto engine heater at a car boot sale. It was new in a box and cost me a quid.Nobody even seemed to know what it was.
I fitted it to my old fairway taxi and on a cold day it gets the engine up to running temprature within ten minutes or so.Since fitting it I replaces the original worn out starter with another one rewired for extra 'go' and the block heater is probably now pretty much redundant.
I have seen block heaters listed in both UK and US, but US prices are a fraction of UK price, but for 120V units. There is a US company (Phillips and Temro) who make a heater, part 3100039 for 1.5" core plug fitting, obvioulsy 120V also. Attempts to email them get rejected with error 550, blocked? They list an agent in OZ, but they also do not repond to emails. Will try the phone soon.
