Radiator Cap Type A - Chase Bays 1.37bar / 20psi
If the spring pressure of the cap is too low, the cap will push out fluid prematurely, filling up the overflow reservoir. When we are driving our cars spiritedly, such sudden pressure spikes are common, and stock limits are not built to handle this. Higher radiator cap pressure effectively raises the boiling point of the coolant, provides an additional safety margin, and prevents air pocket cavitation at the water pump.
Before You Order
〇 Regarding Import Consumption Tax
At the Shaftoya shopping site, we pay the import consumption tax incurred at the time of import on your behalf, so there will be no additional charges beyond the total amount paid at checkout.
〇 Confirmation of Compatibility
Since our entire product database is based on North American vehicles (USDM), please confirm whether or not parts are compatible with Japanese vehicles (JDM) before placing your order. (If you are unsure if a listed product is compatible with your vehicle, please feel free to contact us. Our support team will be happy to check for you.)
If you place an order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if products are sorted by selecting the year, make, and model in the tabs on our top page, it does not necessarily mean they will fit Japanese model vehicles without modification.
All products have been translated into Japanese using translation software. As there may be confusing expressions, please contact us before ordering if you have any questions.
○ Regarding Shipping
Shipping costs are paid at the time of checkout. Shipping estimates are calculated automatically when you enter your shipping address on the checkout page. In rare cases, there may be a significant discrepancy between the automatically calculated shipping cost and the actual cost for large items such as body parts. In such cases, we will contact you individually via email.
Basically, all products are shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please allow plenty of time for your order. If you are in a hurry, please contact us in advance to confirm the delivery date. Note that all products are transported by air; they are never shipped by sea freight.
○ Regarding Compliance with Japanese Vehicle Inspection (Shaken)
All products we handle are basically designed and manufactured outside of Japan. Please note that they are not compliant with the "Japanese vehicle inspection system," and we cannot provide strength study documents or similar for that purpose. Therefore, all parts are sold for the purpose of "use on circuits, private land, or off-road," and installation and use are at your own risk.
○ Regarding Warranty
Please check the contents immediately upon arrival. Since all products are shipped internationally from outside Japan, there may be shipping damage to the packaging or the product. Please understand that for products with shipping damage, defective items, or items different from what was ordered, we will only handle returns, refunds, or exchanges if notified within 7 days of receipt. Furthermore, regarding products sold through us, we will only handle warranty-related matters "exclusively through us." Please note that we do not coordinate with other companies or agencies located within Japan.
