Hi guys

Im in the process of fitting cab radiators in my loadspace and need some advice...

The radiators are from a winterised WOLF with the 300tdi engine and are designed for use with a webasto or similar FBPH there are 2 in the rear and 1 in the battery box, all are mounted and I'm very happy with the copper pipework iv added to fit my installation.

Since i cant afford a webasto, I'm planning to tap into the existing coolant circuit but i don't know enough about the TD5 coolant setup

So my question is; has anyone else done this already, where is best to tap in the take off and return pipes??

Never done it but I'd say coming off your heater hoses would be a good place to start from ! You will have to be careful not to get air locks etc , and maybe a secondary 12volt pump to assist with the flow of extra water capacity !! To be honest I don't think it would be very efficient as they run very cool when in good order !!
You would just have to try it and see !!!
You could have a heat exchanger around your exhaust pipe and an electric pump separate tank etc !! May be more efficient !!
Good project I like the idea a little bit !!!!!!!
 
Waste of time the engine will never get hot enough to run efficiently with all those extra rads onboard. TD5's have great heaters. why do you need additional heating???
 
That is a very valid point mr redhands !! Maybe there is a fault with the heating cooling system!! Or maybe he has a young girlfriend who won't perform below certain temperatures !!! Log burner !!!!!!!
 
Ha ha i wish!
u guys crack me up!

Its because iv a metal bulkhead between the cab and load area and no airflow through, the result is its quite cold and damp in the back, dont want to be chipping ice off the inside when i do norway next year!

From the parts list and diagrams iv got it looks like the wolf works on exactly this principle, it will just be my engine heating the rads instead of the FBH so should be efficient enough if not more so, plus if i win the lottery the infrastructures already there for a webasto!

I remember reading a post from someone ref webasto's and one of the replies mentioned just running it off the engine- didnt know if many ppl had tried it?

Will report back once ic cracked it ;)
 
If a tiny webasto can heat them (bearing in mind iv only used 3 of the 5 in a wolf) and pre heat a 300 engine at -30 in norway, im sure my 2.5 lump can do the business, even with the main rad and the oem heater rad in the same circuit...
Im not talkin hot enough to dry clothes next to! Just warm the air a bit.
 
You wont get enough heat out of the engine , the webasto is 2 or 3 KW , thats why they need one in the first place , s ame as early freelanders , and on some p38 as well

WTF do we know. It never ceases to amaze me. The number of tossers who come on here and ask questions to answers they already have.


If they know that what they are doing to do is gonna work perfectly, the way they intend to do it. Why the Fook bother to ask in the first place.. :mad:

thats a very good question! wtf do you know red?! Clearly not how to read......

If you read the question, i asked where to join the existing pipe work and has anyone else done it

I already know it works.

Lol have a word with yourself, you are a repeat casualty in the war on stupid.

Thats interesting, wolfs use the webasto to pre heat the engine, i thought the heaters were (almost) an after thought to raise the interior temp a little & stop ppl sticking to the metal interior.

Im gonna try it off the engine and see what i get, even if its negligible, iv still got room for a webasto when i win the lottery.....

Oh it'll work!! course it will. You'll get luke warm rads and the engine will never get upto temp. But "It'll work" Why the army splashed out all that money on webasto heaters is beyond me. Money to burn obviously????
Oh and I don't think the army ever fitted em to TD5's did they.. ??? So You KNOW it'll work on a TD5, do you???? How exactly.. :rolleyes:
 
would think the waterpump on the engine would have absolutely no chance of pushing water to extra rads,and as redhand aid it would never heat up anyway

I say radiators, not in the traditional sense; the wolf ones dont have an internal reservoir like the engine rad, its just 15mm domestic standard copper pipe with ali finns slipped over to increase surface area, the extra water volume is minimal and circuit is a simple horse shoe- its maybe 3 meters of extra pipe, will that put too much strain on the pump?

water is pushed around the engine if you add 3mtrs of 15mm pipe to the system you might if you're lucky get some circulation but it'll be minimal and as the fluid cools in the pipework it'll slow down the flow thru the pipework.

It's not gonna work. well no at more than 10% efficiency. and the onboard diagnostics and ECU are gonna be confoosed as fook..

the pump is only designed to pump around the engine and heater matrix,asking it to go 3 meters more is pushing it IMHO,you may get some minimal heat around the circuit but not a hope in hell of it returning to the engine,if it cant return the heat will quickly fade

They fit webasto's to wolfs as part of the winterisation fit, to pre heat the engine in norway when turning the engine at -30 will do serious harm.
Not to heat the cab for us, as i said- operators are an afterthought.
Yep, our tax paying money to burn red - you do pay taxes right?

Im confident it will work on a td5 since the heat output is increased due to the remap (engine and gearbox runs warmer hence the larger volume gearbox sump pan.....)

Anything else red?

Oh right, so a return pump might be needed.
do you know if 12v ones of these are available on their own? Iv never seen them.
 
hiya.
why dont u try 6mm or 8mm micro bore copper, also fit a valve on the return line nearly closed off to restrict the flow, ide take it off the heater matrix pipe work aswell.
