Car Forum / Land Rover Cars / April 2007towing and engine temperature 300 TDi Disco
I towed a club dive boat back from Plymouth to the Midlands on Sunday and so pressed the right pedal harder than usual. The temperature gauge went up above the usual rock steady horizontal to the top of the white sector so I slowed up a bit and whacked the heater full on. With the heater full on I could maintain a fairly constant 60mph and keep the temp gauge in the white sector. It went up on the uphills and came down on the flat / downhills. The rad is clear of external blockage and still has all the fins so I'm expecting to either have to flush the inside of the rad out, or fit a replacement. Questions to the panel if I may. 1) Is a rad backflush with a garden hose likely to help? 2) Is it new rad time? 3) Should I be looking for other maladies? (Heater works fine and no water loss I can detect. No funny slipping belt noises). Cheers Graham PS cracking dives. Saw half a dozen cuttlefish in the hold of a wreck (JEL for Nigel) on one dive - only ever seen 2 before in 300ish dives. > I towed a club dive boat back from Plymouth to the Midlands on Sunday > and so pressed the right pedal harder than usual.

I would suggest in the first instance that was the load "true"? Reason I ask, we had a hoss trailer. At the time I had a v6 scorpio. Empty the trailer would almost stall the trailer, but put a 20kg water carrier at the front of the trailer and it would tow up to 60 no problemo. Found out the axles were slightly twisted and in effect it was like the weight trailer at tractor pulling with zero weight in it, put a 20kg mass up at the front and it went true. if you see what I mean Si >> I towed a club dive boat back from Plymouth to the Midlands on Sunday >> and so pressed the right pedal harder than usual.

The temperature gauge of the 300tdi should be stoicins just under horizontal at any time, I took a 3,5t trailer from Rotterdam to Paris, drive the beach at 80km/u, going up the Gotthard-pass etc, it just doesn't move. Only ones I was low on coulant the gauge went all up, so whenever de needle moves, something is wrong. Could be a leakage, blocked water channels, air bubble, anything, make sure you solve it before you blow you 300tdi! cheers Jurjen > On [DATE], in article [ARTICLE], "[NAME]" <[ADDRESS]> wrote: > [quoted text clipped - 22 lines] > cheers > Jurjen Water level is good so I suspect the rad. I have bought a rangie header tank cap which has a float switch, but haven't fitted it yet. With the heater full on the temp was OK.

Radiator examination noted, but did you have a good look at the back of the radiator (not easy to see)? The little fins tend to drop off the back, leaving the front looking immaculate but giving just the symtoms you describe.

Certainly a possibility worth checking out if the rad looks ok, and the thermostat while you are there - you can just take that out and see if it makes any odds. > Graham Richard Signaturewww.beamends-lrspares.co.uk sales@beamends-lrspares.co.uk I have become... comfortably numb >> I'm off out now for a cracking curry in Leicester so if you do reply >> before tomorrow I may not see it. > > You kucky, lucky <insert expleteive of choice>....

Well, from 12,000 miles away, it has to be said it was way up with the best Indian I have ever had, and the restaurant is unique in my humble experience. It was largely a serve yourself with a large square food "bar" in the middle of the room with starters at the LHS and main courses at the front. Over on the RHS was a selection of fresh veg, and meats that you picked and then handed to a guy with a line of wok's. He stir fried on furnace powered gas rings then added sauce of your choice and noodles or rice. Over on the back wall there were two little "boutiques". One served up curry potato cakes and funny little hard batter balls filled with curry flavoured water. The other did elongated pancakes filled with a spud curry and accompaniments. Way over on the left were desserts. I was with two colleagues visiting from a subsidiary company in Chennai,India. They were totally at home and told me what all of the dishes were, which ones they ate for mid-morning break, which for lunch etc, and the cooks were talking to them in Tamil. Not your regular English "curry house" and 13 quid a head. The name of this esteemed establishment - "Feast India", Melton road. No connection, rabid curry eater only.

Anyway, it *HAD* to be done Sat as I'm off diving again next Friday so sorry, but I had to get hold of one locally (at a premium, rats). Anyway, good news for me is that it's sorted. Just clogged it up the M42 for 20 miles, foot to the floor on the hills and steady as a rock. Just got to fit the RR header cap with the float I got from you before, when I work out the electronics.

Chassis >number starts MA146? Just realised who's asking; should look more closely at headers. The expansion bottle has been replaced... stat was replaced as well last time the head was off, ISTR. I did contemplate the rad, but was unable to get it to overheat in normal use, so concluded it was OK - I did also flush it as well as you can so that won't help you. However, I expect it's the original rad and it did have the engine cooked once (some time back, head was replaced) SignatureAustin Shackles. www.ddol-las.net my opinions are just that Travel The Galaxy!

I've not noticed my temperature gauge move at all when towing our club rib, although I have not covered the sort of distances you describe. JEL is a stunning wreck, especially if you get a bit of sunshine filtering down through the ribs and frames... very envious! What is the vis like down there at the moment? Suspect there are quite a few divers looking in on this newsgroup! Best place I've found for cuttlefish is Babbacombe beach, unfortunately there is not a lot else to see there. Cheers, M. What is the vis like >down there at the moment?

One of our extremely enthusiastic ocean divers estimated the vis as 700 mm on the British Inventor. First time I'd heard that unit used (in that context). David >> PS cracking dives.

You haven't lived until you've donned a stab jacket or ABLJ, done SORTE and run the length of the JEL, perhaps with a twin-set which would give you time for extra penetration... After that you can deploy you DSMB and do 3 @ 5m. It's even better if you get to go home in a land rover. :o) >The rad is clear of external blockage and still has all the fins so I'm >expecting to either have to flush the inside of the rad out, or fit a [quoted text clipped - 5 lines] >3) Should I be looking for other maladies? (Heater works fine and no >water loss I can detect. No funny slipping belt noises). Frankly, I've never yet succeeded in improving a marginal rad by flushing. Consider the sum total of the bore of all the rad tubes, and compare with the inlet and exit pipes, and you can see why: to clear a blockage in a tube requires a noticeable pressure, and you can't achieve this even with a big hose. chemical radflush stuff has similar problems - a blocked tube will never get any chemical in it, except where it's not blocked. Only way I've ever found of solving the "marginal cooling" problem is to replace the rad[1], if it's not caused by external problems like mud in the rad or no fins. Given the time and ability, I daresay you can take the rad apart and poke through all the tubes with a bit of wire, and then re-assemble it. Generally, ICBA. Having said that: BiL Tim had a 3.9 rangie which had no end of these problems, and that was eventually solved by removing the aircon rad and decommissioning the aircon. This then allowed a proper flow of air through the main rad. But that only applies if you have a full-width aircon rad in front of the main one. [1] or re-core, of course, but unless you can find a good rad-place or the rad is unduly expensive to replace, or hard to find, it's easier and not much more to fit a new one.

New rad time methinks. Cheers Graham Graham Bowers <graham@nospam.me.uk> typed: > The rad is clear of external blockage and still has all the fins so I'm > expecting to either have to flush the inside of the rad out, or fit a > replacement. Have you checked the back of the radiator? The front on mine looked pristine, no fin damage and no mud between fins. When I took the fan anf housing off the rear of the rad was missing probably more than half the fins ... it simply couldn't be seen from the front. I was told, and it sounds almost plausible enough, that it's caused by insects/debris going through the first part of the rad freely, but then acting like a bullet and 'exploding' on the way out, taking fins with them ... ;) Once changed the problem went away. > 2) Is it new rad time? Possibly, I dislike flushing as it rarley gets to the root of the problem, though can provide a temporary solution.

Mine was fairly obvious as the front of the engine and under the bonnet was a nice copper colour from the fins that had turned to dust. New rad cured it. Martin Thanks to all for contributions. New rad cured it. Cheers Graham |
