Why's that Nick? I'm genuinely interested to know as in my experience it's been fine Thumbs Up

It's the same viscosity as OAT, it's has all of the correct corrosion inhibitors as OAT and mixes with water as per OAT.

I've experienced no leaks, hose or cooling problems with my Td5 (apart from when the head locating dowels broke)

Having just completed a trip around the Nürburg Ring and a 1500 mile drive there and back at mostly European motorway speeds never once did I have any worries about the coolant system. 2002 90 Td5 Station Wagon

Surely Prestone isn't really an all system coolant? It still mixes with water like any regular antifreeze but is just a different chemical approach. Darren

I ran evans waterless coolant, and I had nothing but problems with the engine. My mate who helped rebuild a Seat diesel engine had similar problems.
The car seemed to be under powered, like I was really forcing the engine to rev.
We had a chat about it a few years ago and he got a link,
Have a read of that Thumbs Up

Now that was a good evaluation

I've just finished fitting a full set of silicon hoses, a full set ie every water hose on her! fit is spot on as they were made using my original hoses as templates & I've checked with the manufacturer Roose motorsport & they are OAT compatible.
If anyone is interested contact Paul Roose, mine is a P15 with egr cooler & new type fuel heater, well worth it.
I'm nothing to do with them other than a happy customer!

Hmmmm

so they advertise a coolant set @ ~£240 and seem to have combined some hoses. Paddocks will sell you a silicone top hose and 2 other long smaller bore hoses at a total of £150

So what about the heater matrix hoses ? That seems to be another option on the roose motorsport site @ ~£100

I've ordered a 3 hose set from www.lhss.co.uk made out of OAT silicon for £130 + VAT + £8.50 p&p so now not sure if that includes hoses to the heater matrix... sounds like it doesn't

I was faced with buying part sets from various suppliers not fully knowing for sure what was included etc. what I do have now from Roose is a set which covers every hose on the water side of my Td5, even the small vent ones. for me I couldn't see the sense in just changing some & not others!
Mine are all now fitted & follow the routing of the original LR rubber ones, so I'm very happy with my purchase.[/u]

I think I might just do the same as you and get something that covers all hoses. Santa - 1977 Series 3 - new chassis, tub, disc brakes,SU Carb
