Radiator has gone on my IS200 '99, tried the radweld option and failed just got back from work and its p in out!
can anyone suggest best place to get one without being ripped off? is main dealer best option? will need to sort one tomorrow so any advice appreciated cheers folks

Try Northern Radiators or United AutoParts Distribution, google them.

I bought a replacement radiator from United AutoParts Distribution last year, cost me £146 inc Vat and delivery. Same part from dealer would have cost me £250. Most of the radiators you buy online have a thinner core, 16mm, the original radiator has a 26mm core- it doesn't make a difference, a thinner core radiator is just as good as the thicker core radiator. I've had a thinner core radiator fitted to my car for a year now, I've had no problems with it.

If you want to save some £££ buy a replacement online, otherwise I suggest you buy a replacement from a Lexus dealer.

You shouldn't have used Radweld, I've heard it can cause problems with your waterpump, basically, Radweld can seize the waterpump, this could lead to problems such as the engine overheating.

never thought of that, how likely is pump to seize? wont be using car untill i fit new radiator so will drain system and refresh when fitted

Or there's this place on ebay that sells them matey for £115+£10 delivery here's the item number : 120216277351

you have pm
