TD5 Heater problem.
« on: October 27, 2006, 22:37:05 »
Can someone please explain why my TD5 will only warm me up in these cold mornings when I'm on the motorway at 70mph????  I'm totally stumped.  When  I slow down I get cool/cold air blowing!!

Cheers

Dodgy thermostat?

Have you checked your coolant level?

Sounds like the thermostat...

Ten minute, £5 fix.... I recomend you do it anyway cuz if it's stuck in the open position, there is a chance that one day it closes not to re-open...at that point cold won't be your problem... warped heads will be!

Check coolant level.

I had this problem last year, but suffered it until I spent 4 hours stuck in a major jam on the M1, rang stealers who said it sounded like my coolant, checked at it was incredibly low, took shed loads to top it up, but then I had warmth and a leak in my radiator, which got replaced las january when lot's of other things got done.

Sometimes you need to get away from the crowd, the only way to do that, is to get a little mud on the tyres.

Will check that first then.  I hope I don't need Land Rover specific stuff to top it up like I do for the PAS/ACe unit!! :lol:

Sully,

Not sure where the thermostat is on a TD5... but on V8's it's right at the front of the block, with the top radiator hose going into it...

Three bolts, a paper gasket and a li'l dinky tin thermostat. The bolts can be a bit of a b*gger to get back in but not a huge problem.

The other advice about coolant level is important as well. Check the coolant level first, monitor the loss, find the leak (if appropriate!).

Good luck

Sulley... as advised earlier... monitor it! That way you'll see when it starts to drop and can start to trace the leak.

Wife and I (both ex squaddies) use the army practice of "First Works Parades". Basically, any time we get in the vehicle (ok... so daily at most) we use the acronym POWER to remind us what to check for.

Petrol - Enough?
Oils - Levels of engine, brake, clutch etc
Water - Coolant & washer
Electrics - All lights work as advertised (amazing the number of wonky or bust lights on the roads these days!)
Rubber - Number (four is useful but five is better!), condition and fill

Whether yer anal like us or use this routine weekly or fotnightly... it's a good practice to get into.

And of course we all check the state of our diff, gear, transfer and swivel oils after an off road session don't we....?    :roll:
