Underheating...

[lacroupade]

I'm sure this is covered somewhere but don't have the energy to look LOL...

Took wifeys truck out to get an Xmas tree tonight and it struggled to warm up on a 20-mile round trip....needle stuck around the 10-11 o'clock position and I was bloody frozen......and when I stopped in -3C the have a squint under the bonnet the dear old vicious fan was running like a demon....

Whats the craic?

Depressed of Llandovery
:(

Ahhh, just found the other thread. Vicious fan definitely working full time so will need to do some more digging. Still, at least its not my car LOL!

blocked heater matrix?? happened to me a few weeks back except mine went to over heat (no heat out of heater though) I changed the thermostat after a good defrosting, added neat coolant and its been mint if not better than ever since.

well the trucks only 7-8 years old and if it had a blocked matrix I'd expect overheating.

Stopped after a 100-mile thrash from Llandovery to Leigh Delamere and took the rad cap off with my bare hands and not a sign of any steam!:eek:

Gauge gets to about 11 o'clock position when doing 90, but at sub-50 its barely off the lower stop and the heater is lukewarm.....going to try blanking the rad at Colins suggestion but thats so bloody 1960s, I can't believe there isn't something wrong....but no idea what?? Viscous fan seems to be running full time as far as I can see, which I wouldn't expect if the rad was only warm as opposed to hot....

well so I read terry, and thats the default fail position isn't it? But when I've had a stat fail on these things the bitch has boiled over in a trice...?

Gonna try a new stat anyway as a cheap starting point so will let you know :thumb2

Yeees, if the stat's stuck open then all the water goes round all the engine, rad and heater. So in silly low temps like now then there's not enough hot in da system to warm the old todger mate :thumbs
Also explains your ability to remove rad cap with your bare hands :rolleyes: oooh I could crush a grape :lol

two jobs to do now; the moaning noise in 4WD on my truck turns not to be the wife, but a CV joint on its way out...except my chances of getting one delivered from Milners in 2010 look remote :(

Ooh I do like a screamer LOL!

Well for El Tel's benefit, it was the stat.:thumb2 After freezing my cobs off driving up from civilisation yesterday into the badlands of Oxfordshire:augie, I nipped into the local motor factors and got a stat...then popped to the old mans to borrow a spanner, but would you believe that after 40 years of building aeroplanes all he has is the biggest collection of imperial spanners in the universe and not a 12mm in sight.:doh

Ended up at dusk in a blizzard in Halfrauds car park (after buying an emergency socket set) with frostbite but swapped it without any drama and within a mile or two she was at the 12 o'clock position and toasty warm.....so it seems my last two stats on the other trucks must have failed in the closed position (cos they overheated immediately), so happy ending anyway! cheers for the replies!:thumb2:thumb2
