Frequently Asked Questions: OE 14257838-00
What if the number on my old pipe does not match this one?
The number to trust is the one stamped on the pipe you are removing, not the one on the box you think you need. This pipe carries OE number 14257838-00, so check the old pipe carries that number before ordering. If it does not match, this is not the right pipe for your car. Take the old part in hand, find the stamped number and check it against the fitment table on this page before you go ahead.
What is this coolant pipe made of?
This is a metal pipe assembly, not a rubber hose. Before you order, take the old pipe off the car and check the OE number, 14257838-00, stamped or printed on it against this listing, since a metal assembly needs to match exactly rather than being trimmed or adjusted to fit. If the numbers agree, you can order with confidence. If you cannot find a number, bring the old part along or use the quote route on this page.
Where does this pipe fit on the car?
Where this pipe sits is under the bonnet, in the engine bay, rather than further along the cooling system. No side or exact mounting position is given beyond that, so do not assume it matches a pipe you have seen fitted on another car. Look at your own engine bay, trace the pipe carrying the matching number and check the side, the position and the fixings holding it in place before you settle on this one.
